FIELD OF INVENTION

The invention relates to CRISPR/CAS-related methods, compositions and components for editing a target nucleic acid sequence, or modulating expression of a target nucleic acid sequence, and applications thereof in connection with cancer immunotherapy comprising adoptive transfer of engineered T cells or T cell precursors.

BACKGROUND

Adoptive transfer of genetically engineered T cells has entered clinical testing as a cancer therapeutic modality. Typically, the approach consists of the following steps: 1) obtaining leukocytes from the subject by apheresis; 2) selecting/enriching for T cells; 3) activating the T cells by cytokine treatment; 4) introducing cloned T cell receptor (TCR) genes or a chimeric antigen receptor (CAR) gene by retroviral transduction, lentiviral transduction or electroporation; 5) expanding the T cells by cytokine treatment; 6) conditioning the subject, usually by lymphodepletion; and 7) infusion of the engineered T cells into the subject.

Sources of cloned TCR genes (TRAC and TRBC) include rare T cell populations isolated from individuals with particular malignancies and T cell clones isolated from T cell receptor-humanized mice immunized with specific tumor antigens or tumor cells. Following adoptive transfer, TCR-engineered T cells recognize their cognate antigen peptides presented by major histocompatibility complex (MHC) proteins on the tumor cell surface. Antigen engagement stimulates signal transduction pathways leading to T cell activation and proliferation. Stimulated T cells then mount a cytotoxic anti-tumor cell response, typically involving a secreted complex comprising Granzyme B, perforin and granulysin, inducing tumor cell apoptosis.

Chimeric antigen receptor (CAR) genes encode artificial T cell receptors comprising an extracellular tumor antigen binding domain, typically derived from the single-chain antibody variable fragment (scFv) domain of a monoclonal antibody, fused via hinge and transmembrane domains to a cytoplasmic effector domain. The effector domain is typically derived from the CD3-zeta chain of the T cell co- receptor complex, and can also include domains derived from CD28 and/or CD 137 receptor proteins. The CAR extra-cellular domain binds the tumor antigen in an MHC-independent manner leading to T cell activation and proliferation, culminating in cytotoxic anti-tumor activity as described for TCR engineered T cells.

To date, at least 15 different tumor antigens have been targeted in clinical trials of engineered T cells. In several trials, anti-tumor activity has been reported. The greatest success has been achieved in hematologic malignancies. For example, adoptive transfer of CAR-T cells engineered to target the B cell antigen, CD 19, led to multiple partial and complete responses in subjects with lymphoma, acute lymphoblastic leukemia, acute lymphocytic leukemia and B-cell acute lymphocytic leukemia. In contrast, trials targeting other tumor types, especially solid tumors, including renal cell carcinoma, neuroblastoma, colorectal cancer, breast cancer, ovarian cancer, melanoma, sarcoma and prostate cancer, have been less successful. In many of these trials, very few patients experienced objective responses. Thus, there is a need to improve the anti-tumor efficacy of adoptively transferred engineered T cells.

SUMMARY

Methods and compositions discussed herein provide for the treatment of cancer using an immunotherapy approach comprising administration of genetically engineered T cells or T cell precursors to a subject. An approach to treat a subject suffering from cancer is to isolate T cells from the subject, genetically modify them to target an antigen expressed by the cancer cells, then re-introduce them into the subject; a process referred to as adoptive cell transfer. Methods to genetically modify T cells include introduction of T cell receptor (TCR) or chimeric antigen receptor (CAR) genes encoding transmembrane TCR or CAR proteins, respectively, which specifically recognize particular cancer antigens. While not wishing to be bound by theory, it is believed that engagement of the tumor-expressed antigen with the antigen binding domain of the TCR or CAR protein initiates a signaling cascade leading to T cell activation, proliferation and, ultimately, destruction of the cancer cell via a cytotoxic immune response (Kershaw et al., 2013 NatRevCancer 13, 525-541).

Adoptive cell transfer utilizing genetically modified T cells has entered clinical testing as a therapeutic for solid and hematologic malignancies. Results to date have been mixed. In hematologic malignancies (especially lymphoma, CLL and ALL), the majority of patients in several Phase 1 and 2 trials exhibited at least a partial response, with some exhibiting complete responses (Kochenderfer, J. N. et al., 2012 Blood 1 19, 2709-2720). However, in most tumor types (including melanoma, renal cell carcinoma and colorectal cancer), fewer responses have been observed (Johnson, L. A. et al., 2009 Blood 1 14, 535-546; Lamers, C. H. et al., 2013 Mol. Ther. 21, 904-912; Warren, R. S. et al., 1998 Cancer Gene Ther. 5, S 1-S2). Thus, there exists a need to improve the efficacy of adoptive transfer of modified T cells in cancer treatment.

Factors limiting the efficacy of genetically modified T cells as cancer therapeutics include (1) T cell proliferation, e.g., limited proliferation of T cells following adoptive transfer; (2) T cell survival, e.g., induction of T cell apoptosis by factors in the tumor environment; and (3) T cell function, e.g., inhibition of cytotoxic T cell function by inhibitory factors secreted by host immune cells and cancer cells. The methods and compositions described herein address these limitations by modifying the expression of T cell-expressed genes that influence T cell proliferation, survival and/or function.

In an embodiment, methods and compositions discussed herein can be used to affect T cell proliferation (e.g., by inactivating genes that inhibit T cell proliferation). In an embodiment, methods and compositions discussed herein can be used to affect T cell survival (e.g., by inactivating genes mediating T cell apoptosis). In an embodiment, methods and composition discussed herein can be used to affect T cell function (e.g., by inactivating genes encoding immunosuppressive and inhibitory (e.g., anergy- inducing) signaling factors). It is contemplated herein that the methods and compositions described above can be utilized individually or in combination to affect one or more of the factors limiting the efficacy of genetically modified T cells as cancer therapeutics, e.g., T cell proliferation, T cell survival, T cell function, or any combination thereof.

Methods and compositions discussed herein can be used to affect T cell proliferation, survival and/or function by altering one or more T-cell expressed genes, e.g., one or more of FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC and/or TRBC genes. In an embodiment, methods and compositions described herein can be used to affect T cell proliferation by altering one or more T-cell expressed genes, e.g., the CBLB and/or PTPN6 gene. In an embodiment, methods and compositions described herein can be used to affect T cell survival by altering one or more T-cell expressed genes, e.g., FAS and/or BID gene. In an embodiment, methods and compositions described herein can be used to affect T cell function by altering one or more T-cell expressed gene or genes, e.g., CTLA4 and/or PDCD1 and/or TRAC and/or TRBC gene.

In one approach, one or more T-cell expressed genes, e.g., FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC and/or TRBC genes, are independently targeted as a targeted knockout or knockdown, e.g., to influence T cell proliferation, survival and/or function. In an embodiment, the approach comprises knocking out or knocking down one T-cell expressed gene (e.g., FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC gene). In another embodiment, the approach comprises independently knocking out or knocking down two T-cell expressed genes, e.g., two of FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises independently knocking out or knocking down three T-cell expressed genes, e.g., three of FAS, BID, CTLA4, PDCDI, CBLB,

PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises independently knocking out or knocking down four T-cell expressed genes, e.g., four of FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises independently knocking out or knocking down five T-cell expressed genes, e.g., five of FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises independently knocking out or knocking down six T-cell expressed genes, e.g., six of FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises independently knocking out or knocking down seven T-cell expressed genes, e.g., seven of FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises independently knocking out or knocking down eight T-cell expressed genes, e.g., each of FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC and TRBC genes.

In addition to the genes described above, a number of other T-cell expressed genes may be targeted to affect the efficacy of engineered T cells. These genes include, but are not limited to TGFBRI, TGFBRII and TGFBRIII (Kershaw et al. 2013 NatRevCancer 13, 525-541). It is contemplated herein that one or more of TGFBRI, TGFBRII or TGFBRIII gene can be altered either individually or in combination using the methods disclosed herein. It is further contemplated that one or more of TGFBRI, TGFBRII or TGFBRIII gene can be altered either individually or in combination with any one or more of the eight genes described above (i.e., FAS, BID, CTLA4, PDCDI, CBLB, PTPN6, TRAC or TRBC gene) using the methods disclosed herein.

In an embodiment, a first and second single strand break can be accompanied by two additional single strand breaks positioned by a third gRNA molecule and a fourth gRNA molecule. For example, the targeting domain of a first and second gRNA molecule are configured such that two single strand breaks are positioned upstream of a T cell target position in the FAS, BID, CTLA4, PDCDl, CBLB,

PTPN6, TRAC or TRBC gene, e.g., within 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500 nucleotides of the target position; and the targeting domains of a third and fourth gRNA molecule are configured such that two single strand breaks are positioned downstream of a T cell target position in the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC gene, e.g., within 1, 2, 3, 4, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, or 500 nucleotides of the target position.

It is contemplated herein that when multiple gRNAs are used to generate (1) two single stranded breaks in close proximity, (2) two double stranded breaks, e.g., flanking a position (e.g., to remove a piece of DNA, e.g., to create a deletion mutation) or to create more than one indel in the gene, e.g., in a coding region, e.g., an early coding region, (3) one double stranded break and two paired nicks flanking a position (e.g., to remove a piece of DNA, e.g., to insert a deletion) or (4) four single stranded breaks, two on each side of a position, that they are targeting the same T cell target position. It is further

contemplated herein that multiple gRNAs may be used to target more than one position in the same gene.

When two or more gRNAs are used to position two or more cleavage events, e.g., double strand or single strand breaks, in a target nucleic acid, it is contemplated that the two or more cleavage events may be made by the same or different Cas9 proteins. For example, when two gRNAs are used to position two double stranded breaks in a target nucleic acid, a single Cas9 nuclease may be used to create both double stranded breaks. When two or more gRNAs are used to position two or more single stranded breaks (also refered to as nicks) in a target nucleic acid, a single Cas9 nickase may be used to create the two or more nicks. When two or more gRNAs are used to position at least one double stranded break and at least one single stranded break in a target nucleic acid, two Cas9 proteins may be used, e.g., one Cas9 nuclease and one Cas9 nickase. It is contemplated that when two or more Cas9 proteins are used that the two or more Cas9 proteins may be delivered sequentially to control specificity of a double stranded versus a single stranded break at the desired position in the target nucleic acid. In another embodiment, when two or more Cas9 proteins are used, the Cas9 proteins may be from different species. For example, when two or more gRNAs are used to position at least one double stranded break and at least one single stranded break in a target nucleic acid, the Cas9 nuclease generating the double stranded break may be from one bacterial species and the Cas9 nickase generating the single stranded break may be from a different bacterial species.

When more than one gene is targeted for alteration in a cell, the targeted nucleic acids may be altered, e.g., cleaved, by one or more Cas9 proteins. For example, if two genes are targeted for alteration, e.g., both genes are targeted for knockout, the same or a different Cas9 protein may be used to target each gene. In one embodiment, both genes (or each gene targeted in a cell), are cleaved by a Cas9 nuclease to generate a double stranded break. In another embodiment, both genes (or each gene targeted in a cell), are cleaved by a Cas9 nuclease to generate a double stranded break. In another embodiment, one or more genes in a cell may be altered by cleavage with a Cas9 nuclease and one or more genes in the same cell may be altered by cleavage with a Cas9 nickase. When two or more Cas9 proteins are used to cut a target nucleic acid, e.g., different genes in a cell, the Cas9 proteins may be from different bacterial species. For example, one or more genes in a cell may be altered by cleavage with a Cas9 protein from one bacterial species, and one or more genes in the same cell may be altered by cleavage with a Cas9 protein from a different bacterial species. It is contemplated that when two or more Cas9 proteins from different species are used that they may be delivered at the same time or delivered sequentially to control specificity of cleavage in the desired gene at the desired position in the target nucleic acid. In some embodiments, the targeting domain of the first gRNA molecule and the targeting domain of the second gRNA molecules are complementary to opposite strands of the target nucleic acid molecule. In some embodiments, the gRNA molecule and the second gRNA molecule are configured such that the PAMs are oriented outward.

In an embodiment, the targeting domain of a gRNA molecule is configured to avoid unwanted target chromosome elements, such as repeat elements, e.g., Alu repeats, in the target domain. The gRNA molecule may be a first, second, third and/or fourth gRNA molecule.

In an embodiment, the targeting domain of a gRNA molecule is configured to position a cleavage event sufficiently far from a preselected nucleotide, e.g., the nucleotide of a coding region, such that the nucleotide is not be altered. In an embodiment, the targeting domain of a gRNA molecule is configured to position an intronic cleavage event sufficiently far from an intron/exon border, or naturally occurring splice signal, to avoid alteration of the exonic sequence or unwanted splicing events. The gRNA molecule may be a first, second, third and/or fourth gRNA molecule, as described herein.

In other embodiments, a position in the coding region, e.g., the early coding region, of the FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC gene is targeted, e.g., for knockout. In an embodiment, the targeting domain comprises a sequence that is the same as, or differs by no more than 1 , 2, 3, 4, or 5 nucleotides from, a targeting domain sequence from any one of Tables 1A-I, Tables 3A-H, Tables 5A-I, Tables 7A-H, Tables 9A-I, Tables 11A-I, Tables 13A-K, Tables 15A-F, Tables 17A-K, Tables 19A-J, Tables 21A-K, Tables 23A-J, Tables 25A-G, Tables 26A-G, Table 27, Table 29, Table 31, or Table 32.

Definitions "Domain", as used herein, is used to describe segments of a protein or nucleic acid. Unless otherwise indicated, a domain is not required to have any specific functional property.

Calculations of homology or sequence identity between two sequences (the terms are used interchangeably herein) are performed as follows. The sequences are aligned for optimal comparison purposes (e.g., gaps can be introduced in one or both of a first and a second amino acid or nucleic acid sequence for optimal alignment and non-homologous sequences can be disregarded for comparison purposes). The optimal alignment is determined as the best score using the GAP program in the GCG software package with a Blossum 62 scoring matrix with a gap penalty of 12, a gap extend penalty of 4, and a frame shift gap penalty of 5. The amino acid residues or nucleotides at corresponding amino acid positions or nucleotide positions are then compared. When a position in the first sequence is occupied by the same amino acid residue or nucleotide as the corresponding position in the second sequence, then the molecules are identical at that position. The percent identity between the two sequences is a function of the number of identical positions shared by the sequences.

"Governing gRNA molecule", as used herein, refers to a gRNA molecule that comprises a targeting domain that is complementary to a target domain on a nucleic acid that comprises a sequence that encodes a component of the CRISPR/Cas system that is introduced into a cell or subject. A governing gRNA does not target an endogenous cell or subject sequence. In an embodiment, a governing gRNA molecule comprises a targeting domain that is complementary with a target sequence on: (a) a nucleic acid that encodes a Cas9 molecule; (b) a nucleic acid that encodes a gRNA which comprises a targeting domain that targets FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC gene (a target gene gRNA); or on more than one nucleic acid that encodes a CRISPR/Cas component, e.g., both (a) and (b). In an embodiment, a nucleic acid molecule that encodes a CRISPR Cas component, e.g., that encodes a Cas9 molecule or a target gene gRNA, comprises more than one target domain that is complementary with a governing gRNA targeting domain. While not wishing to be bound by theory, it is believed that a governing gRNA molecule complexes with a Cas9 molecule and results in Cas9 mediated inactivation of the targeted nucleic acid, e.g., by cleavage or by binding to the nucleic acid, and results in cessation or reduction of the production of a CRISPR/Cas system component. In an embodiment, the Cas9 molecule forms two complexes: a complex comprising a Cas9 molecule with a target gene gRNA, which complex will alter the FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC gene; and a complex comprising a Cas9 molecule with a governing gRNA molecule, which complex will act to prevent further production of a CRISPR/Cas system component, e.g., a Cas9 molecule or a target gene gRNA molecule. In an embodiment, a governing gRNA molecule/Cas9 molecule complex binds to or promotes cleavage of a control region sequence, e.g., a promoter, operably linked to a sequence that encodes a Cas9 molecule, a sequence that encodes a transcribed region, an exon, or an intron, for the Cas9 molecule. In an embodiment, a governing gRNA molecule/Cas9 molecule complex binds to or promotes cleavage of a control region sequence, e.g., a promoter, operably linked to a gRNA molecule, or a sequence that encodes the gRNA molecule. In an embodiment, the governing gRNA, e.g., a Cas9- targeting governing gRNA molecule, or a target gene gRNA-targeting governing gRNA molecule, limits the effect of the Cas9 molecule/target gene gRNA molecule complex-mediated gene targeting. In an embodiment, a governing gRNA places temporal, level of expression, or other limits, on activity of the Cas9 molecule/target gene gRNA molecule complex. In an embodiment, a governing gRNA reduces off- target or other unwanted activity. In an embodiment, a governing gRNA molecule inhibits, e.g., entirely or substantially entirely inhibits, the production of a component of the Cas9 system and thereby limits, or governs, its activity.

"Modulator", as used herein, refers to an entity, e.g., a drug, which can alter the activity (e.g., enzymatic activity, transcriptional activity, or translational activity), amount, distribution, or structure of a subject molecule or genetic sequence. In an embodiment, modulation comprises cleavage, e.g., breaking of a covalent or non-covalent bond, or the forming of a covalent or non-covalent bond, e.g., the attachment of a moiety, to the subject molecule. In an embodiment, a modulator alters the, three dimensional, secondary, tertiary, or quaternary structure, of a subject molecule. A modulator can increase, decrease, initiate, or eliminate a subject activity.

Improving cancer immunotherapy

In an aspect, compositions and methods described herein can be used to affect proliferation of engineered T cells by altering one ore more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene. In order for engineered T cells to mount an effective antitumor response they need to: 1) proliferate adequately following transfer to the subject to provide a sufficient number of specific tumor-targeting T cells; 2) survive in the subject for a length of time sufficient to maintain the required anti-tumor activity; and 3) evade the influence of suppressive factors produced by immune cells, tumor cells and other cells in the tumor environment so that the engineered T cells maintain a functional anti-tumor phenotype. Insufficient proliferation and/or survival, as well as susceptibility to inhibitory factors, can contribute to lack of efficacy of engineered T cells in subjects suffering from cancer. The methods and compositions disclosed herein address these issues in order to improve efficacy of engineered T cells as a cancer therapeutic modality.

In an embodiment, compositions and methods described herein can be used to affect proliferation of engineered T cells by altering the CBLB gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of Casitas B-lineage lymphoma b protein (encoded by CBLB) reduces the requirement for exogenous interleukin signaling to promote proliferation of engineered T cells following transfer to the subject (Stromnes, I. M. et al., 2010 J. Clin. Invest. 120, 3722-3734).

In an embodiment, compositions and methods described herein can be used to affect proliferation of engineered T cells by altering the PTPN6 gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of Src homology region 2 domain-containing phosphatase- 1 protein (encoded by PTPN6) leads to increased short-term accumulation of transferred T cells with subsequently improved anti-tumor activity (Stromnes, I. M. et al., 2012 J. Immunol. 189, 1812-1825).

In an embodiment, compositions and methods described herein can be used to affect proliferation of engineered T cells by altering the FAS gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of the Fas protein will inhibit induction of T cell apoptosis by Fas- ligand; a factor expressed by many cancer types (Dotti, G. et al., 2005 Blood 105, 4677-4684).

In an embodiment, compositions and methods described herein can be used to affect proliferation of engineered T cells by altering the BID gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of the Bid protein prevents the induction of T cell apoptosis following activation of the Fas pathway (Lei, X. Y. et al., 2009 Immunol. Lett. 122, 30-36).

In an embodiment, compositions and methods described herein can be used to decrease the effect of immune suppressive factors on engineered T cells by altering the CTLA4 gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of cytotoxic T-lymphocyte- associated antigen 4 (encoded by CTLA4) abrogates the induction of a non-responsive state ("anergy") following binding of CD80 or CD86 expressed by antigen presenting cells in the tumor environment (Shrikant, P. et al, 1999 Immunity 1 1, 483-493).

In an embodiment, compositions and methods described herein can be used to decrease the effect of immune suppressive factors on engineered T cells by altering the PDCD1 gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of the Programmed Cell Death Protein 1 (encoded by PDCD1) prevents induction of T cell apoptosis by engagement of PD1 Ligand expressed by tumor cells or cells in the tumor environment (Topalian, S. L. et al., 2012 N. Engl. J. Med. 366, 2443-2454).

In an embodiment, compositions and methods described herein can be used to improve T cell specificity and safety by altering the TRAC and/or TRBC gene. While not wishing to be bound by theory, it is considered that reduced or absent expression of T-cell receptors (encoded by TRAC and TRBC) prevents graft vs. host disease by eliminating T cell receptor recognition of and response to host tissues. This approach, therefore, could be used to generate "off the shelf T cells (Torikai et al., 2012 Blood 1 19, 5697-5705). Also, while not wishing to be bound by theory, it is considered that reduced or absent expression of the TRAC and/or TRBC gene will reduce or eliminate mis-pairing of endogenous T cell receptors with exogenously introduced engineered T cell receptors, thus improving therapeutic efficacy (Provasi et al., 2012, Nature Medicine 18, 807-815).

In an embodiment, compositions and methods described herein can be used to decrease one or more of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and TRBC genes to improve treatment of cancer immunotherapy using engineered T cells.

Disclosed herein are the approaches to treat cancer via immunotherapy, using the compositions and methods described herein.

In one approach, one or more of the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and TRBC genes are targeted as a targeted knockout or knockdown, e.g., to affect T cell proliferation, survival and/or function. In an embodiment, said approach comprises knocking out or knocking down one T-cell expressed gene (e.g., FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC gene). In another embodiment, the approach comprises knocking out or knocking down two T-cell expressed genes, e.g., two of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises knocking out or knocking down three T-cell expressed genes, e.g., three of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises knocking out or knocking down four T-cell expressed genes, e.g., four of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises knocking out or knocking down five T-cell expressed genes, e.g., five of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises knocking out or knocking down six T-cell expressed genes, e.g., six of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises knocking out or knocking down seven T-cell expressed genes, e.g., seven of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes. In another embodiment, the approach comprises knocking out or knocking down eight T-cell expressed genes, e.g., each of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and TRBC genes.

In an embodiment, the methods comprise initiating treatment of a subject after disease onset. In an embodiment, the method comprises initiating treatment of a subject well after disease onset, e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 12, 24, or 36 months after onset of cancer.

Methods of altering one or more T cell-expressed genes, e.g.. the FAS. BID. CTLA4. PDCDl. CBLB.

PTPN6. TRAC and/or TRBC gene

As disclosed herein, one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene can be targeted (e.g., altered) by gene editing, e.g., using

CRISPR-Cas9 mediated methods as described herein.

Methods and compositions discussed herein, provide for targeting (e.g., altering) a T cell target position in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6,

TRAC and/or TRBC gene. A T cell target position can be targeted (e.g., altered) by gene editing, e.g., using CRISPR-Cas9 mediated methods to target (e.g. alter) in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene.

Disclosed herein are methods for targeting (e.g., altering) a T cell target position in one or more T cell- expressed genes, e.g., the FAS, BID, CTLA4, PDCD l, CBLB, PTPN6, TRAC and/or TRBC gene.

Targeting (e.g., altering) a T cell target position is achieved, e.g., by:

(1) knocking out one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl,

CBLB, PTPN6, TRAC and/or TRBC gene:

(a) insertion or deletion (e.g., NHEJ-mediated insertion or deletion) of one or more nucleotides in close proximity to or within the coding region of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene, or

(b) deletion (e.g., NHEJ-mediated deletion) of a genomic sequence including at least a portion of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene, or

(2) knocking down one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene mediated by enzymatically inactive Cas9 (eiCas9) molecule or an eiCas9- fusion protein by targeting non-coding region, e.g., a promoter region, of the gene.

All approaches give rise to targeting (e.g., alteration) of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene.

In one embodiment, methods described herein introduce one or more breaks near the coding region in at least one allele of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene. In another embodiment, methods described herein introduce two or more breaks to flank at least a portion of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene. The two or more breaks remove (e.g., delete) a genomic sequence including at least a portion of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCD 1 , CBLB, PTPN6, TRAC and/or TRBC gene. In another embodiment, methods described herein comprise knocking down one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene mediated by enzymatically inactive Cas9 (eiCas9) molecule or an eiCas9-fusion protein by targeting the promoter region of T cell target knockdown position. All methods described herein result in targeting (e.g., alteration) of one or more T cell- expressed genes, e.g., the FAS, BID, CTLA4, PDCD l, CBLB, PTPN6, TRAC and/or TRBC gene.

The targeting (e.g., alteration) of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene can be mediated by any mechanism.

Exemplary mechanisms that can be associated with the alteration of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene include, but are not limited to, non-homologous end joining (e.g., classical or alternative), microhomology -mediated end joining (MMEJ), homology-directed repair (e.g., endogenous donor template mediated), SDSA (synthesis dependent strand annealing), single strand annealing or single strand invasion.

Knocking out one or more T cell-expressed genes, e.g.. the FAS. BID. CTLA4. PDCDl. CBLB. PTPN6. TRAC and/or TRBC gene by introducing an indel or a deletion in one or more T cell-expressed genes, e.g.. the FAS. BID. CTLA4. PDCDl. CBLB. PTPN6. TRAC and/or TRBC gene

In an embodiment, the method comprises introducing an insertion or deletion of one more nucleotides in close proximity to the T cell target knockout position (e.g., the early coding region) of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene genes. As described herein, in one embodiment, the method comprises the introduction of one or more breaks (e.g., single strand breaks or double strand breaks) to the T cell target knockout position, e.g., the coding region (e.g., the early coding region, e.g., within 500bp from the start codon or the remaining coding sequence, e.g., downstream of the first 500bp from the start codon) of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene. While not wishing to be bound by theory, it is believed that NHEJ-mediated repair of the break(s) allows for the NHEJ-mediated introduction of an indel in close proximity to within the T cell target knockout position.

In an embodiment, a single strand break is introduced (e.g., positioned by one gRNA molecule) at or in close proximity to a T cell target knockout position in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCD l, CBLB, PTPN6, TRAC and/or TRBC gene. In an embodiment, a single gRNA molecule (e.g., with a Cas9 nickase) is used to create a single strand break at or in close proximity to the T cell target knockout position, e.g., the coding region (e.g., the early coding region, e.g., within 500bp from the start codon or the remaining coding sequence, e.g., downstream of the first 500bp from the start codon). In an embodiment, the break is positioned to avoid unwanted target chromosome elements, such as repeat elements, e.g., an Alu repeat.

In an embodiment, two gRNA molecules (e.g., with one or two Cas9 nickcases) are used to create two single strand breaks at or in close proximity to the T cell target knockout position, e.g., the coding region (e.g., the early coding region, e.g., within 500bp from the start codon or the remaining coding sequence, e.g., downstream of the first 500bp from the start codon). In an embodiment, the gRNAs molecules are configured such that both single strand breaks are positioned upstream or downstream of the T cell target knockout position. In another embodiment, two gRNA molecules (e.g., with two Cas9 nickcases) are used to create two single strand breaks at or in close proximity to the T cell target knockout position, e.g., the gRNAs molecules are configured such that one single strand break is positioned upstream and a second single strand break is positioned downstream of the T cell target knockout position. In an embodiment, the breaks are positioned to avoid unwanted target chromosome elements, such as repeat elements, e.g., an Alu repeat.

In an embodiment, two sets of breaks (e.g., two double strand breaks) are introduced (e.g., positioned by two gRNA molecules) at or in close proximity to a T cell target knockout position in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene. In an embodiment, two gRNA molecules (e.g., with one or two Cas9 nucleases that are not Cas9 nickases) are used to create two double strand breaks to flank a T cell target knockout position, e.g., the coding region (e.g., the early coding region, e.g., within 500bp from the start codon or the remaining coding sequence, e.g., downstream of the first 500bp from the start codon). In an embodiment, the gRNAs molecules are configured such that both sets of breaks are positioned upstream or downstream of the T cell target knockout position. In an embodiment, the gRNA molecules are configured such that ene-set-ef bfeak-4sone set of breakfs) are positioned upstream and a-seeead-set-of-break isa second set of breakfs) are positioned downstream of the T cell target knockout position. In an embodiment, the breaks are positioned to avoid unwanted target chromosome elements, such as repeat elements, e.g., an Alu repeat.

In an embodiment, two sets of breaks (e.g., one double strand breaks and a pair of single strand breaks) are introduced (e.g., positioned by three gRNA molecules) at or in close proximity to a T cell target knockout position in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC and/or TRBC gene. In an embodiment, three gRNA molecules (e.g., with a Cas9 nuclease and one or two Cas9 nickases) are used to create two sets of breaks to flank a T cell target knockout position, e.g., the coding region (e.g., the early coding region, e.g., within 500bp from the start codon or the remaining coding sequence, e.g., downstream of the first 500bp from the start codon). In an embodiment, the gRNAs molecules are configured such that both sets of breaks are positioned upstream or downstream of the T cell target knockout position.

In an embodiment, two sets of breaks (e.g., two pairs of single strand breaks) are introduced (e.g., positioned by four gRNA molecules) at or in close proximity to a T cell target knockout position in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC and/or TRBC gene. In an embodiment, four gRNA molecules (e.g., with one or more Cas9 nickases) are used to create two sets of breaks to flank a T cell target knockout position, e.g., the coding region (e.g., the early coding region, e.g., within 500bp from the start codon or the remaining coding sequence, e.g., downstream of the first 500bp from the start codon). In an embodiment, the gRNAs molecules are configured such that both sets of breaks are positioned upstream or downstream of the T cell target knockout position. In an embodiment, the gRNA molecules are configured

positioned upstream and a-¾eeeftd-set-& -break-isa second set of break' s ) are positioned downstream of the T cell target knockout position. In an embodiment, the breaks are positioned to avoid unwanted target chromosome elements, such as repeat elements, e.g., an Alu repeat.

In an embodiment, two or more (e.g., three or four) gRNA molecules are used with one Cas9 molecule. In another embodiment, when two ore more (e.g., three or four) gRNAs are used with two or more Cas9 molecules, at least one Cas9 molecule is from a different species than the other Cas9 molecule(s). For example, when two gR A molecules are used with two Cas9 molecules, one Cas9 molecule can be from one species and the other Cas9 molecule can be from a different species. Both Cas9 species are used to generate a single or double-strand break, as desired.

When more than one gene is targeted for alteration in a cell, the targeted nucleic acids may be altered, e.g., cleaved, by one or more Cas9 proteins. For example, if two genes are targeted for alteration, e.g., both genes are targeted for knockout, the same or a different Cas9 protein may be used to target each gene. In one embodiment, both genes (or each gene targeted in a cell), are cleaved by a Cas9 nuclease to generate a double stranded break. In another embodiment, both genes (or each gene targeted in a cell), are cleaved by a Cas9 nuclease to generate a double stranded break. In another embodiment, one or more genes in a cell may be altered by cleavage with a Cas9 nuclease and one or more genes in the same cell may be altered by cleavage with a Cas9 nickase. When two or more Cas9 proteins are used to cut a target nucleic acid, e.g., different genes in a cell, the Cas9 proteins may be from different bacterial species. For example, one or more genes in a cell may be altered by cleavage with a Cas9 protein from one bacterial species, and one or more genes in the same cell may be altered by cleavage with a Cas9 protein from a different bacterial species. It is contemplated that when two or more Cas9 proteins from different species are used that they may be delivered at the same time or delivered sequentially to control specificity of cleavage in the desired gene at the desired position in the target nucleic acid.

In some embodiments, the targeting domain of the first gRNA molecule and the targeting domain of the second gRNA molecules are complementary to opposite strands of the target nucleic acid molecule. In some embodiments, the gRNA molecule and the second gRNA molecule are configured such that the PAMs are oriented outward.

In an embodiment, two gRNAs, e.g., unimolecular (or chimeric) or modular gRNA molecules, are configured to position the two sets of breaks (e.g., two double strand breaks, one double strand break and a pair of single strand breaks or two pairs of single strand breaks) on opposite sides of the T cell target knockout position in one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC and/or TRBC gene.

In another embodiment, when two ore more (e.g., three or four) gRNAs are used with two or more Cas9 molecules, at least one Cas9 molecule is from a different species than the other Cas9 molecule(s). For example, when two gRNA molecules are used with two Cas9 molecules, one Cas9 molecule can be from one species and the other Cas9 molecule can be from a different species. Both Cas9 species are used to generate a single or double-strand break, as desired.

When more than one gene is targeted for alteration in a cell, the targeted nucleic acids may be altered, e.g., cleaved, by one or more Cas9 proteins. For example, if two genes are targeted for alteration, e.g., both genes are targeted for knockout, the same or a different Cas9 protein may be used to target each gene. In one embodiment, both genes (or each gene targeted in a cell), are cleaved by a Cas9 nuclease to generate a double stranded break. In another embodiment, both genes (or each gene targeted in a cell), are cleaved by a Cas9 nuclease to generate a double stranded break. In another embodiment, one or more genes in a cell may be altered by cleavage with a Cas9 nuclease and one or more genes in the same cell may be altered by cleavage with a Cas9 nickase. When two or more Cas9 proteins are used to cut a target nucleic acid, e.g., different genes in a cell, the Cas9 proteins may be from different bacterial species. For example, one or more genes in a cell may be altered by cleavage with a Cas9 protein from one bacterial species, and one or more genes in the same cell may be altered by cleavage with a Cas9 protein from a different bacterial species. It is contemplated that when two or more Cas9 proteins from different species are used that they may be delivered at the same time or delivered sequentially to control specificity of cleavage in the desired gene at the desired position in the target nucleic acid.

In some embodiments, the targeting domain of the first gRNA molecule and the targeting domain of the second gRNA molecules are complementary to opposite strands of the target nucleic acid molecule. In some embodiments, the gRNA molecule and the second gRNA molecule are configured such that the PAMs are oriented outward. Knocking down one or more T cell-expressed genes, e.g.. the FAS. BID. CTLA4. PDCDl. CBLB. and/or PTPN6 gene mediated by an enzymatically inactive Cas9 (eiCas9) molecule

A targeted knockdown approach reduces or eliminates expression of functional FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene product. As described herein, in an embodiment, a targeted knockdown is mediated by targeting an enzymatically inactive Cas9 (eiCas9) molecule or an eiCas9 fused to a transcription repressor domain or chromatin modifying protein to alter transcription, e.g., to block, reduce, or decrease transcription, of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene.

Methods and compositions discussed herein may be used to alter the expression of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene to treat or prevent HIV infection or AIDS by targeting a promoter region of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene. In an embodiment, the promoter region is targeted to knock down expression of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene. A targeted knockdown approach reduces or eliminates expression of functional FAS, BID, CTLA4, PDCDl, CBLB, and/or PTPN6 gene product. As described herein, in an embodiment, a targeted knockdown is mediated by targeting an enzymatically inactive Cas9 (eiCas9) or an eiCas9 fusion protein (e.g., an eiCas9 fused to a transcription repressor domain or chromatin modifying protein) to alter transcription, e.g., to block, reduce, or decrease transcription, of one or more T cell-expressed genes, e.g., the FAS, BID, CTLA4, PDCD 1 , CBLB, P and/or PTPN6 gene.

In an embodiment, one or more eiCas9s may be used to block binding of one or more endogenous transcription factors. In another embodiment, an eiCas9 can be fused to a chromatin modifying protein. Altering chromatin status can result in decreased expression of the target gene. One or more eiCas9s fused to one or more chromatin modifying proteins may be used to alter chromatin status.

When more than one gene is targeted for alteration in a cell, the targeted nucleic acids may be altered, e.g., by one or more eiCas9 proteins or eiCas9 fusion proteins. When two or more eiCas9 proteins or eiCas9 fusion proteins are used the eiCas9 proteins or eiCas9 fusion proteins may be from different bacterial species. For example, one or more genes in a cell may be altered with an eiCas9 protein or eiCas9 fusion protein from one bacterial species, and one or more genes in the same cell may be altered with an eiCas9 protein or eiCas9 fusion protein from a different bacterial species. It is contemplated that when two or more eiCas9 proteins or eiCas9 fusion proteins from different species are used that they may be delivered at the same time or delivered sequentially to control specificity of cleavage in the desired gene at the desired position in the target nucleic acid. While not wishing to be bound by theory, it is considered that adoptive transfer of genetically engineered T cells may provide a potential treatment for cancer. Genes encoding cell surface receptors are inserted into the T cells. The genetically engineered T cells are able to detect tumor associated antigens, which can be used to discriminate tumor cells from most normal tissues.

Knockout or knockdown of one or two alleles of the target gene (e.g., FAS, BID, CTLA4,

PDCDl, CBLB, PTPN6, TRAC or TRBC gene) may be performed after disease onset, but preferably early in the disease course.

I. gRNA Molecules

A gRNA molecule, as that term is used herein, refers to a nucleic acid that promotes the specific targeting or homing of a gRNA molecule/Cas9 molecule complex to a target nucleic acid. gRNA molecules can be unimolecular (having a single RNA molecule), sometimes referred to herein as "chimeric" gRNAs, or modular (comprising more than one, and typically two, separate RNA molecules). A gRNA molecule comprises a number of domains. The gRNA molecule domains are described in more detail below.

Several exemplary gRNA structures, with domains indicated thereon, are provided in Fig. 1. While not wishing to be bound by theory, with regard to the three dimensional form, or intra- or inter- strand interactions of an active form of a gRNA, regions of high complementarity are sometimes shown as duplexes in Fig. 1 and other depictions provided herein.

In an embodiment, a unimolecular, or chimeric, gRNA comprises, preferably from 5' to 3' : a targeting domain (which is complementary to a target nucleic acid in the FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC gene, e.g., a targeting domain from any of Tables 1A-I, Tables 2A-I, Tables 3A-H, Tables 4A-I, Tables 5A-I, Tables 6A-I, Tables 7A-H, Tables 8A-H, Tables 9A-I, Tables 10A-I, Tables 11A-I, Tables 12A-I, Tables 13A-K, Tables 14A-K, Tables 15A-F, Tables 16A- K, Tables 17A-K, Tables 18A-K, Tables 19A-J, Tables 20A-J, Tables 21A-K, Tables 22A-K, Tables 23A-J, Tables 24A-K, Tables 25A-G, Tables 26A-G, Table 27, Table 29, Table 31, or Table 32; a first complementarity domain;

complementarity domain);

optionally, a 5' extension domain;

a second complementarity domain;

a proximal domain; and

optionally, a tail domain.

The domains are discussed briefly below: The Targeting Domain

Fig. 1 provides examples of the placement of targeting domains.

The targeting domain comprises a nucleotide sequence that is complementary, e.g., at least 80, 85, 90, 95, 98 or 99% complementary, e.g., fully complementary, to the target sequence on the target nucleic acid. The targeting domain is part of an R A molecule and will therefore comprise the base uracil (U), while any DNA encoding the gR A molecule will comprise the base thymine (T). While not wishing to be bound by theory, in an embodiment, it is believed that the complementarity of the targeting domain with the target sequence contributes to specificity of the interaction of the gRNA molecule/Cas9 molecule complex with a target nucleic acid. It is understood that in a targeting domain and target sequence pair, the uracil bases in the targeting domain will pair with the adenine bases in the target sequence. In an embodiment, the target domain itself comprises in the 5' to 3' direction, an optional secondary domain, and a core domain. In an embodiment, the core domain is fully complementary with the target sequence. In an embodiment, the targeting domain is 5 to 50 nucleotides in length.

The Linking Domain

Figs. 1A-1G provide examples of linking domains.

A linking domain serves to link the first complementarity domain with the second

complementarity domain of a unimolecular gR A. The linking domain can link the first and second complementarity domains covalently or non-covalently. In an embodiment, the linkage is covalent. In an embodiment, the linking domain covalently couples the first and second complementarity domains, see, e.g., Figs. IB-IE. In an embodiment, the linking domain is, or comprises, a covalent bond interposed between the first complementarity domain and the second complementarity domain. Typically the linking domain comprises one or more, e.g., 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides.

In modular gRNA molecules the two molecules are associated by virtue of the hybridization of the complementarity domains see e.g., Fig. 1A.

A wide variety of linking domains are suitable for use in unimolecular gRNA molecules. Linking domains can consist of a covalent bond, or be as short as one or a few nucleotides, e.g., 1, 2, 3, 4, or 5 nucleotides in length.

In an embodiment, the linking domain has at least 50% homology with a linking domain disclosed herein.

Some or all of the nucleotides of the linking domain can have a modification, e.g., a modification found in Section VIII herein.

In an embodiment, e.g., as shown in Figs. 1A-1B, the second complementarity domain can include sequence that lacks complementarity with the first complementarity domain, e.g., sequence that loops out from the duplexed region.

In an embodiment, the second complementarity domain is 5 to 27 nucleotides in length. In an embodiment, it is longer than the first complementarity region. In an embodiment the second complementary domain is 7 to 27 nucleotides in length. In an embodiment, the second complementary domain is 7 to 25 nucleotides in length.

In an embodiment, the second complementarity domain comprises 3 subdomains, which, in the 5' to 3' direction are: a 5' subdomain, a central subdomain, and a 3' subdomain. In an embodiment, the 5' subdomain is 3 to 25, e.g., 4 to 22, 4 tol8, or 4 to 10, or 3, 4, 5, 6, 7, 8, 9, 10, 1 1, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25 nucleotides in length. In an embodiment, the central subdomain is 1, 2, 3, 4 or 5, e.g., 3, nucleotides in length. In an embodiment, the 3' subdomain is 4 to 9, e.g., 4, 5, 6, 7, 8 or 9 nucleotides in length. In an embodiment, the 5' subdomain and the 3' subdomain of the first complementarity domain, are respectively, complementary, e.g., fully complementary, with the 3' subdomain and the 5' subdomain of the second complementarity domain.

The second complementarity domain can share homology with or be derived from a naturally occurring second complementarity domain. In an embodiment, it has at least 50% homology with a second complementarity domain disclosed herein, e.g., an S. pyogenes, S. aureus, N. meningtidis, or S. thermophilus, first complementarity domain.

pyogenes, S. aureus, N. meningtidis, or S. thermophilus, proximal domain.

Some or all of the nucleotides of the proximal domain can have a modification, e.g., a modification found in Section VIII herein.

A Tail Domain

Figs. 1A-1G provide examples of tail domains.

As can be seen by inspection of the tail domains in Fig. 1A and Figs. 1B-1F, a broad spectrum of tail domains are suitable for use in gRNA molecules. In an embodiment, the tail domain is 0 (absent), 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 nucleotides in length. In embodiment, the tail domain nucleotides are from or share homology with sequence from the 5' end of a naturally occurring tail domain, see e.g., Fig. ID or IE. In an embodiment, the tail domain includes sequences that are complementary to each other and which, under at least some physiological conditions, form a duplexed region.

In an embodiment, the tail domain is absent or is 1 to 50 nucleotides in length. In an

embodiment, the tail domain can share homology with or be derived from a naturally occurring proximal tail domain. In an embodiment, it has at least 50% homology with a tail domain disclosed herein, e.g., an S. pyogenes, S. aureus, N. meningtidis, or S. thermophilus, tail domain.

In an embodiment, the tail domain includes nucleotides at the 3 ' end that are related to the method of in vitro or in vivo transcription. When a T7 promoter is used for in vitro transcription of the gRNA, these nucleotides may be any nucleotides present before the 3 ' end of the DNA template. When a U6 promoter is used for in vivo transcription, these nucleotides may be the sequence UIJIJUUU. When alternate pol-III promoters are used, these nucleotides may be various numbers or uracil bases or may include alternate bases.

The domains of gRNA molecules are described in more detail below. The Targeting Domain

The strand of the target nucleic acid comprising the core domain target is referred to herein as the "complementary strand" of the target nucleic acid.

In an embodiment, the targeting domain nucleotides do not comprise modifications, e.g., modifications of the type provided in Section VIII. However, in an embodiment, the targeting domain comprises one or more modifications, e.g., modifications that render it less susceptible to degradation or more bio-compatible, e.g., less immunogenic. By way of example, the backbone of the targeting domain can be modified with a phosphorothioate, or other modification(s) from Section VIII. In an embodiment, a nucleotide of the targeting domain can comprise a 2' modification, e.g., a 2-acetylation, e.g., a 2' methylation, or other modification(s) from Section VIII.

In some embodiments, the targeting domain includes 1, 2, 3, 4, 5, 6, 7 or 8 or more modifications.

In an embodiment, the targeting domain comprises as many as 1, 2, 3, or 4 modifications within 5 nucleotides of its 3 ' end.

In some embodiments, the targeting domain comprises modifications at two consecutive nucleotides, e.g., two consecutive nucleotides that are within 5 nucleotides of the 5' end of the targeting domain, within 5 nucleotides of the 3 ' end of the targeting domain, or more than 5 nucleotides away from one or both ends of the targeting domain.

In an embodiment, no two consecutive nucleotides are modified within 5 nucleotides of the 5' end of the targeting domain, within 5 nucleotides of the 3' end of the targeting domain, or within a region that is more than 5 nucleotides away from one or both ends of the targeting domain. In an embodiment, no nucleotide is modified within 5 nucleotides of the 5' end of the targeting domain, within 5 nucleotides of the 3 ' end of the targeting domain, or within a region that is more than 5 nucleotides away from one or both ends of the targeting domain.

Modifications in the targeting domain can be selected to not interfere with targeting efficacy, which can be evaluated by testing a candidate modification in the system described in Section IV.

gR As having a candidate targeting domain having a selected length, sequence, degree of

complementarity, or degree of modification, can be evaluated in a system in Section IV. The candidate targeting domain can be placed, either alone, or with one or more other candidate changes in a gRNA molecule/Cas9 molecule system known to be functional with a selected target and evaluated.

In some embodiments, all of the modified nucleotides are complementary to and capable of hybridizing to corresponding nucleotides present in the target domain. In other embodiments, 1, 2, 3, 4, 5, 6, 7 or 8 or more modified nucleotides are not complementary to or capable of hybridizing to corresponding nucleotides present in the target domain. In an embodiment, the targeting domain comprises, preferably in the 5'→3' direction: a secondary domain and a core domain. These domains are discussed in more detail below.

The Core Domain and Secondary Domain of the Targeting Domain

II. Methods for Designing gRNAs

Methods for designing gRNAs are described herein, including methods for selecting, designing and validating targeting domains. Exemplary targeting domains are also provided herein. Targeting domains discussed herein can be incorporated into the gRNAs described herein.

Methods for selection and validation of target sequences as well as off-target analyses are described, e.g., in Mali et al., 2013 SCIENCE 339(6121): 823-826; Hsu et al. NAT BIOTECHNOL, 31(9):

827-32; Fu et al., 2014 NAT BlOTECHNOL, doi: 10.1038/nbt.2808. PubMed PMID: 24463574; Heigwer et al., 2014 NAT METHODS l l(2): 122-3. doi: 10.1038/nmeth.2812. PubMed PMID: 24481216; Bae et al., 2014 BIOINFORMATICS PubMed PMID: 24463181 ; Xiao A et al., 2014 BlOINFORMATICS PubMed PMID: 24389662.

In some embodiments, a software tool can be used to optimize the choice of gRNA within a user's target sequence, e.g., to minimize total off-target activity across the genome. Off target activity may be other than cleavage. For example, for each possible gRNA choice using S. pyogenes Cas9, software tools can identify all potential off-target sequences (preceding either NAG or NGG PAMs) across the genome that contain up to a certain number (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10) of mismatched base-pairs. The cleavage efficiency at each off-target sequence can be predicted, e.g., using an experimentally-derived weighting scheme. Each possible gRNA can then be ranked according to its total predicted off-target cleavage; the top-ranked gRNAs represent those that are likely to have the greatest on-target and the least off-target cleavage. Other functions, e.g., automated reagent design for gRNA vector construction, primer design for the on-target Surveyor assay, and primer design for high- throughput detection and quantification of off-target cleavage via next-generation sequencing, can also be included in the tool. Candidate gRNA molecules can be evaluated by art-known methods or as described in Section IV herein.

In some embodiments, gRNAs for use with S. pyogenes, S. aureus, and N. meningitidis Cas9s were identified using a DNA sequence searching algorithm, e.g., using a custom gRNA design software based on the public tool cas-offinder (Bae et al. Bioinformatics. 2014; 30(10): 1473-1475). Said custom gRNA design software scores guides after calculating their genomewide off-target propensity. Typically matches ranging from perfect matches to 7 mismatches are considered for guides ranging in length from 17 to 24. Once the off-target sites were computationally determined, an aggregate score was calculated for each guide and summarized in a tabular output using a web-interface. In addition to identifying potential gRNA sites adjacent to PAM sequences, the software also identifies all PAM adjacent sequences that differ by 1, 2, 3 or more nucleotides from the selected gRNA sites. Genomic DNA sequence for each gene were obtained from the UCSC Genome browser and sequences were screened for repeat elements using the publicly available RepeatMasker program. RepeatMasker searches input DNA sequences for repeated elements and regions of low complexity. The output is a detailed annotation of the repeats present in a given query sequence.

Following identification, gRNAs were ranked into tiers based on on one or more of their distance to the target site, their orthogonality and presence of a 5' G (based on identification of close matches in the human genome containing a relavant PAM, e.g., in the case of S. pyogenes, a NGG PAM, in the case of S. aureus, NNGRR (e.g, a NNGRRT or NNGRRV) PAM, and in the case of N. meningtidis, a

NNNNGATT or NNNNGCTT PAM). Orthogonality refers to the number of sequences in the human genome that contain a minimum number of mismatches to the target sequence. A "high level of orthogonality" or "good orthogonality" may, for example, refer to 20-mer targeting domains that have no identical sequences in the human genome besides the intended target, nor any sequences that contain one or two mismatches in the target sequence. Targeting domains with good orthogonality are selected to minimize off-target DNA cleavage. It is to be understood that this is a non-limiting example and that a variety of strategies could be utilized to identify gRNAs for use with S. pyogenes, S. aureus and N.

meningitidis or other Cas9 enzymes.

Two design and tiering strategies were utilized to identify exemplary gRNAs for use with S. pyogenes, S. aureus and N. meningitidis Cas9 enzymes.

First Strategy for Designing and Tiering gRNAs

In the first strategy, gRNAs for use with the S. pyogenes Cas9 were identified using the publicly available web-based ZiFiT server (Fu et al., Improving CRISPR-Cas nuclease specificity using truncated guide RNAs. Nat Biotechnol. 2014 Jan 26. doi: 10.1038/nbt.2808. PubMed PMID: 24463574, for the original references see Sander et al., 2007, NAR 35:W599-605; Sander et al., 2010, NAR 38: W462-8). In addition to identifying potential gRNA sites adjacent to PAM sequences, the software also identifies all PAM adjacent sequences that differ by 1, 2, 3 or more nucleotides from the selected gRNA sites.

Genomic DNA sequences for each gene were obtained from the UCSC Genome browser and sequences were screened for repeat elements using the publicly available Repeat-Masker program. RepeatMasker searches input DNA sequences for repeated elements and regions of low complexity. The output is a detailed annotation of the repeats present in a given query sequence. Following identification, gRNAs for use with a S. pyogenes Cas9 were ranked into 5 tiers. The targeting domains for first tier gRNA molecules were selected based on their distance to the target site, their orthogonality and presence of a 5' G (based on the ZiFiT identification of close matches in the human genome containing an NGG PAM). Orthogonality refers to the number of sequences in the human genome that contain a minimum number of mismatches to the target sequence. A "high level of orthogonality" or "good orthogonality" may, for example, refer to 20-mer gRNAs that have no identical sequences in the human genome nor any sequences that contain one or two mismatches in the target sequence. Targeting domains with good orthogonality are selected to miminize off-target DNA cleavage. For all targets, both 17-mer and 20-mer gRNAs were designed. gRNAs were also selected both for single-gRNA nuclease cutting and for the dual gRNA nickase strategy. Criteria for selecting gRNAs and the determination for which gRNAs can be used for which strategy is based on several considerations: gRNAs were identified for both single-gRNA nuclease cleavage and for a dual-gRNA paired "nickase" strategy. Criteria for selecting gRNAs and the determination for which gRNAs can be used for the dual-gRNA paired "nickase" strategy is based on two considerations:

gRNA pairs should be oriented on the DNA such that PAMs are facing out and cutting with the D 1 OA Cas9 nickase will result in 5' overhangs.

An assumption that cleaving with dual nickase pairs will result in deletion of the entire intervening sequence at a reasonable frequency. However, cleaving with dual nickase pairs canalso often result in indel mutations at the site of only one of the gRNAs. Candidate pair members can be tested for how efficiently they remove the entire sequence versus just causing indel mutations at the site of one gRNA. The targeting domains for first tier gRNA molecules were selected based on (1) a reasonable distance to the target position, e.g., within the first 500bp of coding sequence downstream of start codon, (2) a high level of orthogonality, and (3) the presence of a 5' G. For selection of second tier gRNAs, the requirement for a 5'G was removed, but the distance restriction was required and a high level of orthogonality was required. Third tier selection used the same distance restriction and the requirement for a 5'G, but removed the requirement of good orthogonality. Fourth tier selection used the same distance restriction but remove the requirement of good orthogonality and start with a 5'G. Fifth tier selection removed the requirement of good orthogonality and a 5'G, and a longer sequence (e.g., the rest of the coding sequence, e.g., additional 500 bp upstream or downstream to the transcription target site) was scanned. Note that tiers are non-inclusive (each gRNA is listed only once). In certain instances, no gRNA was identified based on the criteria of the particular tier.

As discussed above, gRNAs were identified for single-gRNA nuclease cleavage as well as for a dual-gRNA paired "nickase" strategy, as indicated.

gRNAs for use with the N. meningitidis and S. aureus Cas9s were identified manually by scanning genomic DNA sequence for the presence of PAM sequences. These gRNAs were separated into two tiers. For first tier gRNAs, targeting domains were selected within the first 500bp of coding sequence downstream of start codon. For second tier gRNAs, targeting domains were selected within the remaining coding sequence (downstream of the first 500bp). Note that tiers are non-inclusive (each gRNA is listed only once for the strategy). In certain instances, no gRNA was identified based on the criteria of the particular tier.

Exemplary Targeting Domains (First Strategy)

Below are tables for providing exemplary targeting domains according to the first design and tiering strategy. As an example, for S. pyogenes, S. aureus and N. meningtidis targets, 17-mer, or 20-mer targeting domains were designed.

Table 1A provides targeting domains for knocking out the FAS gene using S. pyogenes Cas9 selected according to first tier parameters. The targeting domains bind within the first 500bp of coding sequence downstream of start codon, have good orthogonality, and start with G. It is contemplated herein that the targeting domain hybridizes to the target domain through complementary base pairing. Any of the targeting domains in the table can be used with a S. pyogenes Cas9 molecule that generates a double stranded break (Cas9 nuclease) or a single-stranded break (Cas9 nickase). In an embodiment, dual targeting is used to create two nicks on opposite DNA strands by using S. pyogenes Cas9 nickases with two targeting domains that are complementary to opposite DNA strands, e.g., a gRNA comprising any minus strand targeting domain may be paired with any gRNA comprising a plus strand targeting domain provided that the two gRNAs are oriented on the DNA such that PAMs face outward and the distance between the 5' ends of the gRNAs is 0-50bp. In an embodiment, two gRNAs are used to target two Cas9 nucleases or two Cas9 nickases, e.g., a gRNA with a targeting domain from Group A can be paired with a gRNA with any targeting domain from Group B as shown in Table 1.

Second Strategy for Designing and Tiering gRNAs

The second strategy used to identify gRNAs for use with S. pyogenes, S. aureus and N.

meningtidis Cas9 enzymes differed from the first strategy as follows.

Guide RNAs (gRNAs) for use with S. pyogenes, S. aureus and N. meningtidis Cas9s were identified using a DNA sequence searching algorithm. Guide RNA design was carried out using a custom guide RNA design software based on the public tool cas-offinder (reference:Cas-OFFinder: a fast and versatile algorithm that searches for potential off-target sites of Cas9 RNA-guided endonucleases., Bioinformatics. 2014 Feb 17. Bae S, Park J, Kim JS. PMID:24463181). Said custom guide RNA design software scores guides after calculating their genomewide off-target propensity. Typically matches ranging from perfect matches to 7 mismatches are considered for guides ranging in length from 17 to 24. Once the off-target sites are computationally determined , an aggregate score is calculated for each guide and summarized in a tabular output using a web-interface. In addition to identifying potential gRNA sites adjacent to PAM sequences, the software also identifies all PAM adjacent sequences that differ by 1, 2, 3 or more nucleotides from the selected gRNA sites. Genomic DNA sequence for each gene was obtained from the UCSC Genome browser and sequences were screened for repeat elements using the publically available RepeatMasker program. RepeatMasker searches input DNA sequences for repeated elements and regions of low complexity. The output is a detailed annotation of the repeats present in a given query sequence.

Following identification, gRNAs were ranked into tiers based on their distance to the target site or their orthogonality (based on identification of close matches in the human genome containing a relavant PAM, e.g., in the case of S. pyogenes, a NGG PAM, in the case of S. aureus, NNGRR (e.g, a NNGRRT or NNGRRV) PAM, and in the case of N. meningtidiss, a NNNNGATT or NNNNGCTT PAM.

Orthogonality refers to the number of sequences in the human genome that contain a minimum number of mismatches to the target sequence. A "high level of orthogonality" or "good orthogonality" may, for example, refer to 20-mer gRNAs that have no identical sequences in the human genome besides the intended target, nor any sequences that contain one or two mismatches in the target sequence. Targeting domains with good orthogonality are selected to minimize off-target DNA cleavage.

As an example, for S. pyogenes and N. meningtidiss targets, 17-mer, or 20-mer gRNAs were designed. As another example, for S. aureus targets, 18-mer, 19-mer, 20-mer, 21-mer, 22-mer, 23-mer and 24-mer gRNAs were designed. Targeting domains, disclosed herein, may comprise the 17-mer described in Targeting domains, disclosed herein, may comprise a 17-mer described in Tables 13 A-K, Tables 14A-K, Tables 15A-F, Tables 16A-K, Tables 17A-K, Tables 18 A-K, Tables 19A-J, Tables 20A-J, Tables 21A-K, Tables 22A-K, Tables 23A-J, Tables 24A-K, Tables 25A-G, Tables 26A-G, Table 27,

gRNAs were identified for both single-gRNA nuclease cleavage and for a dual-gRNA paired "nickase" strategy. Criteria for selecting gRNAs and the determination for which gRNAs can be used for which strategy is based on several considerations:

1. gRNA pairs should be oriented on the DNA such that PAMs are facing out and cutting with the D10A Cas9 nickase will result in 5' overhangs.

2. An assumption that cleaving with dual nickase pairs will result in deletion of the entire intervening sequence at a reasonable frequency. However, it will also often result in indel mutations at the site of only one of the gRNAs. Candidate pair members can be tested for how efficiently they remove the entire sequence versus just causing indel mutations at the site of one gRNA.

The Targeting Domains discussed herein can be incorporated into the gRNAs described herein. For designing knock out strategies, in some embodiments, the targeting domains for tier 1 gRNA molecules for S. pyogenes were selected based on their distance to the target site and their orthogonality (PAM is NGG). The targeting domains for tier 1 gRNA molecules were selected based on (1) a reasonable distance to the target position, e.g., within the first 500bp of coding sequence downstream of start codon and (2) a high level of orthogonality. For selection of tier 2 gRNAs, a high level of orthogonality was not required. Tier 3 gRNAs removed the requirement of good orthogonality and a longer sequence (e.g., the rest of the coding sequence) was scanned. Note that tiers are non-inclusive (each gRNA is listed only once). In certain instances, no gRNA was identified based on the criteria of the particular tier.

For designing knock out strategies, in some embodiments, the targeting domain for tier 1 gRNA molecules for N. meningtidis were selected within the first 500bp of the coding sequence and had a high level of orthogonality. The targeting domain for tier 2 gRNA molecules for N. meningtidis were selected within the first 500bp of the coding sequence and did not require high orthogonality. The targeting domain for tier 3 gRNA molecules for N. meningtidis were selected within a remainder of coding sequence downstream of the 500bp. Note that tiers are non-inclusive (each gRNA is listed only once). In certain instances, no gRNA was identified based on the criteria of the particular tier. For designing knock out strategies, in some embodiments, the targeting domain for tier 1 grNA molecules for S. aureus were selected within the first 500bp of the coding sequence, had a high level of orthogonality, and contained a NNGRRT PAM. The targeting domain for tier 2 grNA molecules for S. aureus were selected within the first 500bp of the coding sequence, no level of orthogonality was required, and contained a NNGRRT PAM. The targeting domain for tier 3 gRNA molecules for S. aureus were selected within the remainder of the coding sequence downstream and contained a NNGRRT PAM. The targeting domain for tier 4 gRNA molecules for S. aureus were selected within the first 500bp of the coding sequence and contained a NNGRRV PAM. The targeting domain for tier 5 gRNA molecules for S. aureus were selected within the remainder of the coding sequence downstream and contained a NNGRRV PAM. Note that tiers are non-inclusive (each gRNA is listed only once). In certain instances, no gRNA was identified based on the criteria of the particular tier.

For designing of gRNA molecules for knocking down strategies, in some embodiments, the targeting domain for tier 1 gRNA molecules for S. pyogenes were selected within the first 500bp upstream and downstream of the transcription start site and had a high level of orthogonality. The targeting domain for tier 2 gRNA molecules for S. pyogenes were selected within the first 500bp upstream and downstream of the transcription start site and did not require high orthogonality. The targeting domain for tier 3 gRNA molecules for S. pyogenes were selected within the additional 500bp upstream and downstream of transcription start site (e.g., extending to lkb up and downstream of the transcription start site). Note that tiers are non-inclusive (each gRNA is listed only once). In certain instances, no gRNA was identified based on the criteria of the particular tier.

The targeting domain for tier 4 gRNA molecules for S. aureus were selected within 500bp upstream and downstream of transcription start site and PAM is NNGRRV. The targeting domain for tier 5 gRNA molecules for S. aureus were selected within the additional 500bp upstream and downstream of transcription start site (extending to lkb up and downstream of the transcription start site) and PAM is NNGRRV. Note that tiers are non-inclusive (each gRNA is listed only once). In certain instances, no gRNA was identified based on the criteria of the particular tier.

Exemplary Targeting Domains (Second Strategy)

Below are tables for providing exemplary targeting domains according to the second design and tiering strategy. As an example, for S. pyogenes and N. meningtidis targets, 17-mer, or 20-mer gRNAs were designed. As another example, for S. aureus targets, 18-mer, 19-mer, 20-mer, 21-mer, 22-mer, 23- mer and 24-mer gRNAs were designed.

Table 13A provides targeting domains for knocking out the FAS gene using S. pyogenes Cas9 selected according to first tier parameters.

A Cas9 molecule, or Cas9 polypeptide, as that term is used herein, refers to a molecule or polypeptide that can interact with a gR A molecule and, in concert with the gR A molecule, homes or localizes to a site which comprises a target domain and PAM sequence. Cas9 molecule and Cas9 polypeptide, as those terms are used herein, refer to naturally occurring Cas9 molecules and to engineered, altered, or modified Cas9 molecules or Cas9 polypeptides that differ, e.g., by at least one amino acid residue, from a reference sequence, e.g., the most similar naturally occurring Cas9 molecule or a sequence of Table 100.

Cas9 Domains

Crystal structures have been determined for two different naturally occurring bacterial Cas9 molecules (Jinek et al., Science, 343(6176): 1247997, 2014) and for S. pyogenes Cas9 with a guide R A (e.g., a synthetic fusion of crRNA and tracrR A) (Nishimasu et al., Cell, 156:935-949, 2014; and Anders et al., Nature, 2014, doi: 10.1038/naturel3579).

A naturally occurring Cas9 molecule comprises two lobes: a recognition (REC) lobe and a nuclease (NUC) lobe; each of which further comprises domains described herein. Figs. 8A-8B provide a schematic of the organization of important Cas9 domains in the primary structure. The domain nomenclature and the numbering of the amino acid residues encompassed by each domain used throughout this disclosure is as described in Nishimasu et al. The numbering of the amino acid residues is with reference to Cas9 from S. pyogenes.

The REC lobe comprises the arginine-rich bridge helix (BH), the REC 1 domain, and the REC2 domain. The REC lobe does not share structural similarity with other known proteins, indicating that it is a Cas9-specific functional domain. The BH domain is a long a-helix and arginine rich region and comprises amino acids 60-93 of the sequence of S. pyogenes Cas9. The REC1 domain is important for recognition of the repeat: anti-repeat duplex, e.g., of a gRNA or a tracrRNA, and is therefore critical for Cas9 activity by recognizing the target sequence. The REC1 domain comprises two REC1 motifs at amino acids 94 to 179 and 308 to 717 of the sequence of S. pyogenes Cas9. These two REC1 domains, though separated by the REC2 domain in the linear primary structure, assemble in the tertiary structure to form the REC 1 domain. The REC2 domain, or parts thereof, may also play a role in the recognition of the repeat: anti-repeat duplex. The REC2 domain comprises amino acids 180-307 of the sequence of S. pyogenes Cas9.

The NUC lobe comprises the RuvC domain (also referred to herein as RuvC-like domain), the HNH domain (also referred to herein as HNH-like domain), and the PAM-interacting (PI) domain. The RuvC domain shares structural similarity to retroviral integrase superfamily members and cleaves a single strand, e.g., the non-complementary strand of the target nucleic acid molecule. The RuvC domain is assembled from the three split RuvC motifs (RuvC I, RuvCII, and RuvCIII, which are often commonly referred to in the art as RuvCI domain, or N-terminal RuvC domain, RuvCII domain, and RuvCIII domain) at amino acids 1-59, 718-769, and 909-1098, respectively, of the sequence of S. pyogenes Cas9. Similar to the REC 1 domain, the three RuvC motifs are linearly separated by other domains in the primary structure, however in the tertiary structure, the three RuvC motifs assemble and form the RuvC domain. The HNH domain shares structural similarity with HNH endonucleases, and cleaves a single strand, e.g., the complementary strand of the target nucleic acid molecule. The HNH domain lies between the RuvC II-III motifs and comprises amino acids 775-908 of the sequence of S. pyogenes Cas9. The PI domain interacts with the PAM of the target nucleic acid molecule, and comprises amino acids 1099-1368 of the sequence of S. pyogenes Cas9.

Nuclease and Helicase Activities

In an embodiment, the Cas9 molecule or Cas9 polypeptide is capable of cleaving a target nucleic acid molecule. Typically wild type Cas9 molecules cleave both strands of a target nucleic acid molecule. Cas9 molecules and Cas9 polypeptides can be engineered to alter nuclease cleavage (or other properties), e.g., to provide a Cas9 molecule or Cas9 peolypeptide which is a nickase, or which lacks the ability to cleave target nucleic acid. A Cas9 molecule or Cas9 polypeptide that is capable of cleaving a target nucleic acid molecule is referred to herein as an eaCas9 molecule or eaCas9 polypeptide

In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises one or more of the following activities:

a nickase activity, i.e., the ability to cleave a single strand, e.g., the non-complementary strand or the complementary strand, of a nucleic acid molecule;

a double stranded nuclease activity, i.e., the ability to cleave both strands of a double stranded nucleic acid and create a double stranded break, which in an embodiment is the presence of two nickase activities;

an endonuclease activity;

an exonuclease activity; and

a helicase activity, i.e., the ability to unwind the helical structure of a double stranded nucleic acid.

In an embodiment, an enzymatically active or eaCas9 molecule or eaCas9 polypeptide cleaves both strands and results in a double stranded break. In an embodiment, an eaCas9 molecule cleaves only one strand, e.g., the strand to which the gRNA hybridizes to, or the strand complementary to the strand the gRNA hybridizes with. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises cleavage activity associated with an HNH-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises cleavage activity associated with an N-terminal RuvC-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises cleavage activity associated with an HNH-like domain and cleavage activity associated with an N-terminal RuvC-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises an active, or cleavage competent, HNH-like domain and an inactive, or cleavage incompetent, N-terminal RuvC-like domain. In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises an inactive, or cleavage incompetent, HNH-like domain and an active, or cleavage competent, N-terminal RuvC-like domain.

Some Cas9 molecules or Cas9 polypeptides have the ability to interact with a gRNA molecule, and in conjunction with the gRNA molecule localize to a core target domain, but are incapable of cleaving the target nucleic acid, or incapable of cleaving at efficient rates. Cas9 molecules having no, or no substantial, cleavage activity are referred to herein as an eiCas9 molecule or eiCas9 polypeptide. For example, an eiCas9 molecule or eiCas9 polypeptide can lack cleavage activity or have substantially less, e.g., less than 20, 10, 5, 1 or 0.1 % of the cleavage activity of a reference Cas9 molecule or eiCas9 polypeptide, as measured by an assay described herein. Targeting and PAMs

A Cas9 molecule or Cas9 polypeptide, is a polypeptide that can interact with a guide RNA (gRNA) molecule and, in concert with the gRNA molecule, localizes to a site which comprises a target domain and a PAM sequence.

In an embodiment, the ability of an eaCas9 molecule or eaCas9 polypeptide to interact with and cleave a target nucleic acid is PAM sequence dependent. A PAM sequence is a sequence in the target nucleic acid. In an embodiment, cleavage of the target nucleic acid occurs upstream from the PAM sequence. EaCas9 molecules from different bacterial species can recognize different sequence motifs (e.g., PAM sequences). In an embodiment, an eaCas9 molecule of S. pyogenes recognizes the sequence motif NGG, NAG, NGA and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. See, e.g., Mali et al, SCIENCE 2013; 339(6121): 823-826. In an embodiment, an eaCas9 molecule of S. thermophilus recognizes the sequence motif NGGNG and/or NNAGAAW (W = A or T) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from these sequences. See, e.g., Horvath et al, SCIENCE 2010; 327(5962): 167-170, and Deveau et al, J BACTERIOL 2008; 190(4): 1390-1400. In an embodiment, an eaCas9 molecule of S. mutans recognizes the sequence motif NGG and/or NAAR (R = A or G)) and directs cleavage of a core target nucleic acid sequence 1 to 10, e.g., 3 to 5 base pairs, upstream from this sequence. See, e.g., Deveau et al, J BACTERIOL 2008; 190(4): 1390-1400. In an embodiment, an eaCas9 molecule of S. aureus recognizes the sequence motif NNGRR (R = A or G) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. In an embodiment, an eaCas9 molecule of S. aureus recognizes the sequence motif N GRRT (R = A or G) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. In an embodiment, an eaCas9 molecule of S. aureus recognizes the sequence motif N GRRV (R = A or G) and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. In an embodiment, an eaCas9 molecule of N. meningitidis recognizes the sequence motif N GATT or N GCTT (R = A or G, V = A, G or C and directs cleavage of a target nucleic acid sequence 1 to 10, e.g., 3 to 5, base pairs upstream from that sequence. See, e.g., Hou et ah, PNAS EARLY EDITION 2013, 1-6. The ability of a Cas9 molecule to recognize a PAM sequence can be determined, e.g., using a transformation assay described in Jinek et ah, SCIENCE 2012 337:816. In the aforementioned embodiments, N can be any nucleotide residue, e.g., any of A, G, C or T.

As is discussed herein, Cas9 molecules can be engineered to alter the PAM specificity of the Cas9 molecule.

Engineered or Altered Cas9 Molecules and Cas9 Polypeptides

Cas9 molecules and Cas9 polypeptides described herein, e.g., naturally occurring Cas9 molecules, can possess any of a number of properties, including: nickase activity, nuclease activity (e.g., endonuclease and/or exonuclease activity); helicase activity; the ability to associate functionally with a gRNA molecule; and the ability to target (or localize to) a site on a nucleic acid (e.g., PAM recognition and specificity). In an embodiment, a Cas9 molecule or Cas9 polypeptide can include all or a subset of these properties. In typical embodiments, a Cas9 molecule or Cas9 polypeptide has the ability to interact with a gRNA molecule and, in concert with the gRNA molecule, localize to a site in a nucleic acid. Other activities, e.g., PAM specificity, cleavage activity, or helicase activity can vary more widely in Cas9 molecules and Cas9 polypeptides.

Cas9 molecules include engineered Cas9 molecules and engineered Cas9 polypeptides

(engineered, as used in this context, means merely that the Cas9 molecule or Cas9 polypeptide differs from a reference sequences, and implies no process or origin limitation). An engineered Cas9 molecule or Cas9 polypeptide can comprise altered enzymatic properties, e.g., altered nuclease activity, (as compared with a naturally occurring or other reference Cas9 molecule) or altered helicase activity. As discussed herein, an engineered Cas9 molecule or Cas9 polypeptide can have nickase activity (as opposed to double strand nuclease activity). In an embodiment an engineered Cas9 molecule or Cas9 polypeptide can have an alteration that alters its size, e.g., a deletion of amino acid sequence that reduces its size, e.g., without significant effect on one or more, or any Cas9 activity. In an embodiment, an engineered Cas9 molecule or Cas9 polypeptide can comprise an alteration that affects PAM recognition. E.g., an engineered Cas9 molecule can be altered to recognize a PAM sequence other than that recognized by the endogenous wild-type PI domain. In an embodiment a Cas9 molecule or Cas9 polypeptide can differ in sequence from a naturally occurring Cas9 molecule but not have significant alteration in one or more Cas9 activities. Cas9 molecules or Cas9 polypeptides with desired properties can be made in a number of ways, e.g., by alteration of a parental, e.g., naturally occurring, Cas9 molecules or Cas9 polypeptides, to provide an altered Cas9 molecule or Cas9 polypeptide having a desired property. For example, one or more mutations or differences relative to a parental Cas9 molecule, e.g., a naturally occurring or engineered Cas9 molecule, can be introduced. Such mutations and differences comprise: substitutions (e.g., conservative substitutions or substitutions of non-essential amino acids); insertions; or deletions. In an embodiment, a Cas9 molecule or Cas9 polypeptide can comprises one or more mutations or differences, e.g., at least 1, 2, 3, 4, 5, 10, 15, 20, 30, 40 or 50 mutations but less than 200, 100, or 80 mutations relative to a reference, e.g., a parental, Cas9 molecule.

In an embodiment, a mutation or mutations do not have a substantial effect on a Cas9 activity, e.g. a Cas9 activity described herein. In an embodiment, a mutation or mutations have a substantial effect on a Cas9 activity, e.g. a Cas9 activity described herein.

In an embodiment, a Cas9 molecule or Cas9 polypeptide comprises a cleavage property that differs from naturally occurring Cas9 molecules, e.g., that differs from the naturally occurring Cas9 molecule having the closest homology. For example, a Cas9 molecule or Cas9 polypeptide can differ from naturally occurring Cas9 molecules, e.g., a Cas9 molecule of S. pyogenes, as follows: its ability to modulate, e.g., decreased or increased, cleavage of a double stranded nucleic acid (endonuclease and/or exonuclease activity), e.g., as compared to a naturally occurring Cas9 molecule (e.g., a Cas9 molecule of S. pyogenes); its ability to modulate, e.g., decreased or increased, cleavage of a single strand of a nucleic acid, e.g., a non-complementary strand of a nucleic acid molecule or a complementary strand of a nucleic acid molecule (nickase activity) , e.g., as compared to a naturally occurring Cas9 molecule (e.g., a Cas9 molecule of S. pyogenes); or the ability to cleave a nucleic acid molecule, e.g., a double stranded or single stranded nucleic acid molecule, can be eliminated.

The reference Cas9 molecule can by a naturally occurring unmodified Cas9 molecule, e.g., a naturally occurring Cas9 molecule such as a Cas9 molecule of S. pyogenes, or S. thermophilus. In an embodiment, the reference Cas9 molecule is the naturally occurring Cas9 molecule having the closest sequence identity or homology.

In an embodiment, an eaCas9 molecule or eaCas9 polypeptide comprises an inactive, or cleavage incompetent, HNH domain and an active, or cleavage competent, N-terminal RuvC-like domain (e.g., an N-terminal RuvC-like domain described herein, e.g., SEQ ID NO:8, SEQ ID NO:9, SEQ ID NO: 10, SEQ ID NO : 1 1 , SEQ ID NO : 12, SEQ ID NO : 13 , SEQ ID NO : 14, SEQ ID NO : 15, or SEQ ID NO : 16).

Alterations in the Ability to Cleave One or Both Strands of a Target Nucleic Acid

In an embodiment, exemplary Cas9 activities comprise one or more of PAM specificity, cleavage activity, and helicase activity. A mutation(s) can be present, e.g., in: one or more RuvC-like domain, e.g., an N-terminal RuvC-like domain; an HNH-like domain; a region outside the RuvC-like domains and the HNH-like domain.

In an embodiment, a Cas9 molecule or Cas9 polypeptide is an eiCas9 molecule or eiCas9 polypeptide comprising one or more differences in a RuvC domain and/or in an HNH domain as compared to a reference Cas9 molecule, and the eiCas9 molecule or eiCas9 polypeptide does not cleave a nucleic acid, or cleaves with significantly less efficiency than does wildype, e.g., when compared with wild type in a cleavage assay, e.g., as described herein, cuts with less than 50, 25, 10, or 1% of a reference Cas9 molecule, as measured by an assay described herein.

Whether or not a particular sequence, e.g., a substitution, may affect one or more activity, such as targeting activity, cleavage activity, etc, can be evaluated or predicted, e.g., by evaluating whether the mutation is conservative or by the method described in Section IV. In an embodiment, a "non-essential" amino acid residue, as used in the context of a Cas9 molecule, is a residue that can be altered from the wild-type sequence of a Cas9 molecule, e.g., a naturally occurring Cas9 molecule, e.g., an eaCas9 molecule, without abolishing or more preferably, without substantially altering a Cas9 activity (e.g., cleavage activity), whereas changing an "essential" amino acid residue results in a substantial loss of activity (e.g., cleavage activity).

In an embodiment, a Cas9 molecule or Cas9 polypeptide comprises a cleavage property that differs from naturally occurring Cas9 molecules, e.g., that differs from the naturally occurring Cas9 molecule having the closest homology. For example, a Cas9 molecule or Cas9 polypeptide can differ from naturally occurring Cas9 molecules, e.g., a Cas9 molecule of S aureus, S. pyogenes, or C. jejuni as follows: its ability to modulate, e.g., decreased or increased, cleavage of a double stranded break

(endonuclease and/or exonuclease activity), e.g., as compared to a naturally occurring Cas9 molecule (e.g., a Cas9 molecule of S aureus, S. pyogenes, or C. jejuni); its ability to modulate, e.g., decreased or increased, cleavage of a single strand of a nucleic acid, e.g., a non-complementary strand of a nucleic acid molecule or a complementary strand of a nucleic acid molecule (nickase activity), e.g., as compared to a naturally occurring Cas9 molecule (e.g., a Cas9 molecule of S aureus, S. pyogenes, or C. jejuni); or the ability to cleave a nucleic acid molecule, e.g., a double stranded or single stranded nucleic acid molecule, can be eliminated.

The reference Cas9 molecule can be a naturally occurring unmodified Cas9 molecule, e.g., a naturally occurring Cas9 molecule such as a Cas9 molecule of S. pyogenes, S.

thermophilus, S. aureus, C. jejuni or N. meningitidis. In an embodiment, the reference Cas9 molecule is the naturally occurring Cas9 molecule having the closest sequence identity or homology.

For example, a fragment of a naturally occurring Cas9 molecule of one species can be fused to a fragment of a Cas9 molecule of a second species. As an example, a fragment of Cas9 molecule of S. pyogenes comprising an N-terminal RuvC-like domain can be fused to a fragment of Cas9 molecule of a species other than S. pyogenes (e.g., S. thermophilus) comprising an HNH-like domain.

Cas9 Molecules With Altered PAM Recognition Or No PAM Recognition

Naturally occurring Cas9 molecules can recognize specific PAM sequences, for example the PAM recognition sequences described above for, e.g., S. pyogenes, S. thermophilus, S. mutans, S. aureus and N. meningitidis.

In an embodiment, a Cas9 molecule or Cas9 polypeptide has the same PAM specificities as a naturally occurring Cas9 molecule. In other embodiments, a Cas9 molecule or Cas9 polypeptide has a PAM specificity not associated with a naturally occurring Cas9 molecule, or a PAM specificity not associated with the naturally occurring Cas9 molecule to which it has the closest sequence homology. For example, a naturally occurring Cas9 molecule can be altered, e.g., to alter PAM recognition, e.g., to alter the PAM sequence that the Cas9 molecule or Cas9 polypeptide recognizes to decrease off target sites and/or improve specificity; or eliminate a PAM recognition requirement. In an embodiment, a Cas9 molecule can be altered, e.g., to increase length of PAM recognition sequence and/or improve Cas9 specificity to high level of identity, e.g., to decrease off target sites and increase specificity. In an embodiment, the length of the PAM recognition sequence is at least 4, 5, 6, 7, 8, 9, 10 or 15 amino acids in length.

Cas9 molecules or Cas9 polypeptides that recognize different PAM sequences and/or have reduced off-target activity can be generated using directed evolution. Exemplary methods and systems that can be used for directed evolution of Cas9 molecules are described, e.g., in Esvelt et al. Nature 201 1, 472(7344): 499-503. Candidate Cas9 molecules can be evaluated, e.g., by methods described in Section IV.

Alterations of the PI domain, which mediates PAM recognition, are discussed below.

Synthetic Cas9 Molecules and Cas9 Polypeptides with Altered PI Domains

Current genome- editing methods are limited in the diversity of target sequences that can be targeted by the PAM sequence that is recognized by the Cas9 molecule utilized. A synthetic Cas9 molecule (or Syn-Cas9 molecule), or synthetic Cas9 polypeptide (or Syn-Cas9 polypeptide), as that term is used herein, refers to a Cas9 molecule or Cas9 polypeptide that comprises a Cas9 core domain from one bacterial species and a functional altered PI domain, i.e., a PI domain other than that naturally associated with the Cas9 core domain, e.g., from a different bacterial species.

In an embodiment, the altered PI domain recognizes a PAM sequence that is different from the PAM sequence recognized by the naturally-occurring Cas9 from which the Cas9 core domain is derived. In an embodiment, the altered PI domain recognizes the same PAM sequence recognized by the naturally- occurring Cas9 from which the Cas9 core domain is derived, but with different affinity or specificity. A Syn-Cas9 molecule or Syn-Cas9 polypetide can be, respectively, a Syn-eaCas9 molecule or Syn-eaCas9 polypeptide or a Syn-eiCas9 molecule Syn-eiCas9 polypeptide.

An exemplary Syn-Cas9 molecule or Syn-Cas9 polypetide comprises:

a) a Cas9 core domain, e.g., a Cas9 core domain from Table 100 or 200, e.g., a S. aureus, S. pyogenes, or C. jejuni Cas9 core domain; and

b) an altered PI domain from a species X Cas9 sequence selected from Tables 400 and 500.

In an embodiment, the RKR motif (the PAM binding motif) of said altered PI domain comprises: differences at 1 , 2, or 3 amino acid residues; a difference in amino acid sequence at the first, second, or third position; differences in amino acid sequence at the first and second positions, the first and third positions, or the second and third positions; as compared with the sequence of the RKR motif of the native or endogenous PI domain associated with the Cas9 core domain.

In an embodiment, the Cas9 core domain comprises the Cas9 core domain from a species X Cas9 from Table 100 and said altered PI domain comprises a PI domain from a species Y Cas9 from Table 100.

In an embodiment, the RKR motif of the species X Cas9 is other than the RKR motif of the species Y Cas9.

In an embodiment, the Cas9 molecule or Cas9 polypeptide further comprises a linker disposed between said Cas9 core domain and said altered PI domain.

In an embodiment, the linker comprises: a linker described elsewhere herein disposed between the Cas9 core domain and the heterologous PI domain. Suitable linkers are further described in Section V.

Exemplary altered PI domains for use in Syn-Cas9 molecules are described in Tables 400 and 500. The sequences for the 83 Cas9 orthologs referenced in Tables 400 and 500 are provided in Table 100. Table 300 provides the Cas9 orthologs with known PAM sequences and the corresponding RKR motif.

In an embodiment, a Syn-Cas9 molecule or Syn-Cas9 polypeptide may also be size-optimized, e.g., the Syn-Cas9 molecule or Syn-Cas9 polypeptide comprises one or more deletions, and optionally one or more linkers disposed between the amino acid residues flanking the deletions. In an embodiment, a Syn-Cas9 molecule or Syn-Cas9 polypeptide comprises a REC deletion.

Size-Optimized Cas9 Molecules and Cas9 Polypeptides

Engineered Cas9 molecules and engineered Cas9 polypeptides described herein include a Cas9 molecule or Cas9 polypeptide comprising a deletion that reduces the size of the molecule while still retaining desired Cas9 properties, e.g., essentially native conformation, Cas9 nuclease activity, and/or target nucleic acid molecule recognition. Provided herein are Cas9 molecules or Cas9 polypeptides comprising one or more deletions and optionally one or more linkers, wherein a linker is disposed between the amino acid residues that flank the deletion. Methods for identifying suitable deletions in a reference Cas9 molecule, methods for generating Cas9 molecules with a deletion and a linker, and methods for using such Cas9 molecules will be apparent to one of ordinary skill in the art upon review of this document.

A Cas9 molecule, e.g., a S. aureus, S. pyogenes, or C. jejuni, Cas9 molecule, having a deletion is smaller, e.g., has reduced number of amino acids, than the corresponding naturally-occurring Cas9 molecule. The smaller size of the Cas9 molecules allows increased flexibility for delivery methods, and thereby increases utility for genome-editing. A Cas9 molecule or Cas9 polypeptide can comprise one or more deletions that do not substantially affect or decrease the activity of the resultant Cas9 molecules or Cas9 polypeptides described herein. Activities that are retained in the Cas9 molecules or Cas9 polypeptides comprising a deletion as described herein include one or more of the following:

a nickase activity, i.e., the ability to cleave a single strand, e.g., the non-complementary strand or the complementary strand, of a nucleic acid molecule; a double stranded nuclease activity, i.e., the ability to cleave both strands of a double stranded nucleic acid and create a double stranded break, which in an embodiment is the presence of two nickase activities;

an endonuclease activity;

an exonuclease activity;

a helicase activity, i.e., the ability to unwind the helical structure of a double stranded nucleic acid;

and recognition activity of a nucleic acid molecule, e.g., a target nucleic acid or a gRNA.

Activity of the Cas9 molecules or Cas9 polypeptides described herein can be assessed using the activity assays described herein or in the art.

Identifying regions suitable for deletion

Suitable regions of Cas9 molecules for deletion can be identified by a variety of methods.

Naturally- occurring orthologous Cas9 molecules from various bacterial species, e.g., any one of those listed in Table 100, can be modeled onto the crystal structure of S. pyogenes Cas9 (Nishimasu et al., Cell, 156:935-949, 2014) to examine the level of conservation across the selected Cas9 orthologs with respect to the three-dimensional conformation of the protein. Less conserved or unconserved regions that are spatially located distant from regions involved in Cas9 activity, e.g., interface with the target nucleic acid molecule and/or gRNA, represent regions or domains are candidates for deletion without substantially affecting or decreasing Cas9 activity. REC-Optimized Cas9 Molecules and Cas9 Polypeptides

A REC-optimized Cas9 molecule, or a REC-optimized Cas9 polypeptide, as that term is used herein, refers to a Cas9 molecule or Cas9 polypeptide that comprises a deletion in one or both of the REC2 domain and the RE1 _CT domain (collectively a REC deletion), wherein the deletion comprises at least 10% of the amino acid residues in the cognate domain. A REC-optimized Cas9 molecule or Cas9 polypeptide can be an eaCas9 molecule or eaCas9 polypetide, or an eiCas9 molecule or eiCas9 polypeptide. An exemplary REC-optimized Cas9 molecule or REC-optimized Cas9 polypeptide comprises:

a) a deletion selected from:

i) a REC2 deletion;

ii) a REClcT deletion; or

iii) a REC 1 SUB deletion.

Optionally, a linker is disposed between the amino acid residues that flank the deletion. In an embodiment a Cas9 molecule or Cas9 polypeptide includes only one deletion, or only two deletions. A Cas9 molecule or Cas9 polypeptide can comprise a REC2 deletion and a RECI _CT deletion. A Cas9 molecule or Cas9 polypeptide can comprise a REC2 deletion and a REC 1 _SUB deletion.

Generally, the deletion will contain at least 10% of the amino acids in the cognate domain, e.g., a REC2 deletion will include at least 10% of the amino acids in the REC2 domain. A deletion can comprise: at least 10, 20, 30, 40, 50, 60, 70, 80, or 90% of the amino acid residues of its cognate domain; all of the amino acid residues of its cognate domain; an amino acid residue outside its cognate domain; a plurality of amino acid residues outside its cognate domain; the amino acid residue immediately N terminal to its cognate domain; the amino acid residue immediately C terminal to its cognate domain; the amino acid residue immediately N terminal to its cognate and the amino acid residue immediately C terminal to its cognate domain; a plurality of, e.g., up to 5, 10, 15, or 20, amino acid residues N terminal to its cognate domain; a plurality of, e.g., up to 5, 10, 15, or 20, amino acid residues C terminal to its cognate domain; a plurality of, e.g., up to 5, 10, 15, or 20, amino acid residues N terminal to to its cognate domain and a plurality of e.g., up to 5, 10, 15, or 20, amino acid residues C terminal to its cognate domain.

In an embodiment, a deletion does not extend beyond: its cognate domain; the N terminal amino acid residue of its cognate domain; the C terminal amino acid residue of its cognate domain.

A REC-optimized Cas9 molecule or REC-optimized Cas9 polypeptide can include a linker disposed between the amino acid residues that flank the deletion. Suitable linkers for use between the amino acid resides that flank a REC deletion in a REC-optimized Cas9 molecule is disclosed in Section V.

In an embodiment, a REC-optimized Cas9 molecule or REC-optimized Cas9 polypeptide comprises an amino acid sequence that, other than any REC deletion and associated linker, has at least 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 99, or 100% homology with the amino acid sequence of a naturally occurring Cas 9, e.g., a Cas9 molecule described in Table 100, e.g., a S. aureus Cas9 molecule, a S.

pyogenes Cas9 molecule, or a C. jejuni Cas9 molecule.

In an embodiment, a a REC-optimized Cas9 molecule or REC-optimized Cas9 polypeptide comprises an amino acid sequence that, other than any REC deletion and associated linker, differs by no more than 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, or 25, amino acid residues from the amino acid sequence of a naturally occurring Cas 9, e.g., a Cas9 molecule described in Table 100, e.g., a S. aureus Cas9 molecule, a S. pyogenes Cas9 molecule, or a C. jejuni Cas9 molecule.

In an embodiment, a REC-optimized Cas9 molecule or REC-optimized Cas9 polypeptide comprises an amino acid sequence that, other than any REC deletion and associate linker, differs by no more than 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, or 25% of the, amino acid residues from the amino acid sequence of a naturally occurring Cas 9, e.g., a Cas9 molecule described in Table 100, e.g., a S. aureus Cas9 molecule, a S. pyogenes Cas9 molecule, or a C. jejuni Cas9 molecule.

For sequence comparison, typically one sequence acts as a reference sequence, to which test sequences are compared. When using a sequence comparison algorithm, test and reference sequences are entered into a computer, subsequence coordinates are designated, if necessary, and sequence algorithm program parameters are designated. Default program parameters can be used, or alternative parameters can be designated. The sequence comparison algorithm then calculates the percent sequence identities for the test sequences relative to the reference sequence, based on the program parameters. Methods of alignment of sequences for comparison are well known in the art. Optimal alignment of sequences for comparison can be conducted, e.g., by the local homology algorithm of Smith and Waterman, (1970) Adv. Appl. Math. 2:482c, by the homology alignment algorithm of Needleman and Wunsch, (1970) J. Mol. Biol. 48:443, by the search for similarity method of Pearson and Lipman, (1988) Proc. Nat'l. Acad. Sci. USA 85:2444, by computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, WI), or by manual alignment and visual inspection (see, e.g., Brent et al., (2003) Current Protocols in Molecular Biology).

Two examples of algorithms that are suitable for determining percent sequence identity and sequence similarity are the BLAST and BLAST 2.0 algorithms, which are described in Altschul et al., (1977) Nuc. Acids Res. 25:3389-3402; and Altschul et al., (1990) J. Mol. Biol. 215:403-410, respectively. Software for performing BLAST analyses is publicly available through the National Center for

Biotechnology Information.

The percent identity between two amino acid sequences can also be determined using the algorithm of E. Meyers and W. Miller, (1988) Comput. Appl. Biosci. 4: 1 1-17) which has been incorporated into the ALIGN program (version 2.0), using a PAM120 weight residue table, a gap length penalty of 12 and a gap penalty of 4. In addition, the percent identity between two amino acid sequences can be determined using the Needleman and Wunsch (1970) J. Mol. Biol. 48:444-453) algorithm which has been incorporated into the GAP program in the GCG software package (available at www.gcg.com), using either a Blossom 62 matrix or a PAM250 matrix, and a gap weight of 16, 14, 12, 10, 8, 6, or 4 and a length weight of 1, 2, 3, 4, 5, or 6.

Nucleic Acids Encoding Cas9 Molecules

Nucleic acids encoding the Cas9 molecules or Cas9 polypeptides, e.g., an eaCas9 molecule or eaCas9 polypeptide, are provided herein.

Exemplary nucleic acids encoding Cas9 molecules or Cas9 polypeptides are described in Cong et al., Science 2013, 399(6121):819-823; Wang et al., Cell 2013, 153(4):910-918; Mali et al., Science 2013, 399(6121):823-826; Jinek et al., Science 2012, 337(6096):816-821. Another exemplary nucleic acid encoding a Cas9 molecule or Cas9 polypeptide is shown in black in Fig. 8. In an embodiment, a nucleic acid encoding a Cas9 molecule or Cas9 polypeptide can be a synthetic nucleic acid sequence. For example, the synthetic nucleic acid molecule can be chemically modified, e.g., as described in Section VIII. In an embodiment, the Cas9 mRNA has one or more (e.g., all of the following properties: it is capped, polyadenylated, substituted with 5-methylcytidine and/or pseudouridine.

In addition, or alternatively, the synthetic nucleic acid sequence can be codon optimized, e.g., at least one non-common codon or less-common codon has been replaced by a common codon. For example, the synthetic nucleic acid can direct the synthesis of an optimized messenger mRNA, e.g., optimized for expression in a mammalian expression system, e.g., described herein.

If any of the above Cas9 sequences are fused with a peptide or polypeptide at the C-terminus, it is understood that the stop codon will be removed.

Other Cas Molecules and Cas Polypeptides

Various types of Cas molecules or Cas polypeptides can be used to practice the inventions disclosed herein. In some embodiments, Cas molecules of Type II Cas systems are used. In other embodiments, Cas molecules of other Cas systems are used. For example, Type I or Type III Cas molecules may be used. Exemplary Cas molecules (and Cas systems) are described, e.g., in Haft et al., PLoS Computational Biology 2005, 1 (6): e60 and Makarova et al., Nature Review Microbiology 201 1 , 9:467-477, the contents of both references are incorporated herein by reference in their entirety.

IV. Functional Analysis of Candidate Molecules Candidate Cas9 molecules, candidate gRNA molecules, candidate Cas9 molecule/gRNA molecule complexes, can be evaluated by art-known methods or as described herein. For example, exemplary methods for evaluating the endonuclease activity of Cas9 molecule are described, e.g., in Jinek et al, SCIENCE 2012, 337(6096):816-821.

Binding and Cleavage Assay: Testing the endonuclease activity of Cas9 molecule

The ability of a Cas9 molecule/gRNA molecule complex to bind to and cleave a target nucleic acid can be evaluated in a plasmid cleavage assay. In this assay, synthetic or in vz ^' /ro-transcribed gRNA molecule is pre-annealed prior to the reaction by heating to 95°C and slowly cooling down to room temperature. Native or restriction digest-linearized plasmid DNA (300 ng (~8 nM)) is incubated for 60 min at 37°C with purified Cas9 protein molecule (50-500 nM) and gRNA (50-500 nM, 1 : 1) in a Cas9 plasmid cleavage buffer (20 mM HEPES pH 7.5, 150 mM KC1, 0.5 mM DTT, 0.1 mM EDTA) with or without 10 mM MgCl ₂ . The reactions are stopped with 5X DNA loading buffer (30% glycerol, 1.2% SDS, 250 mM EDTA), resolved by a 0.8 or 1% agarose gel electrophoresis and visualized by ethidium bromide staining. The resulting cleavage products indicate whether the Cas9 molecule cleaves both DNA strands, or only one of the two strands. For example, linear DNA products indicate the cleavage of both DNA strands. Nicked open circular products indicate that only one of the two strands is cleaved.

Alternatively, the ability of a Cas9 molecule/gRNA molecule complex to bind to and cleave a target nucleic acid can be evaluated in an oligonucleotide DNA cleavage assay. In this assay, DNA oligonucleotides (10 pmol) are radiolabeled by incubating with 5 units T4 polynucleotide kinase and ~3-6 pmol (-20-40 mCi) [γ-32Ρ]-ΑΤΡ in IX T4 polynucleotide kinase reaction buffer at 37°C for 30 min, in a 50 reaction. After heat inactivation (65°C for 20 min), reactions are purified through a column to remove unincorporated label. Duplex substrates (100 nM) are generated by annealing labeled oligonucleotides with equimolar amounts of unlabeled complementary oligonucleotide at 95°C for 3 min, followed by slow cooling to room temperature. For cleavage assays, gRNA molecules are annealed by heating to 95°C for 30 s, followed by slow cooling to room temperature. Cas9 (500 nM final concentration) is pre-incubated with the annealed gRNA molecules (500 nM) in cleavage assay buffer (20 mM HEPES pH 7.5, 100 mM KC1, 5 mM MgC12, 1 mM DTT, 5% glycerol) in a total volume of 9 μΐ. Reactions are initiated by the addition of 1 μΐ target DNA (10 nM) and incubated for 1 h at 37°C.

Reactions are quenched by the addition of 20 μΐ of loading dye (5 mM EDTA, 0.025% SDS, 5% glycerol in formamide) and heated to 95°C for 5 min. Cleavage products are resolved on 12% denaturing polyacrylamide gels containing 7 M urea and visualized by phosphorimaging. The resulting cleavage products indicate that whether the complementary strand, the non-complementary strand, or both, are cleaved. One or both of these assays can be used to evaluate the suitability of a candidate gRNA molecule or candidate Cas9 molecule.

Binding Assay: Testing the binding of Cas9 molecule to target DNA

Exemplary methods for evaluating the binding of Cas9 molecule to target DNA are described, e.g., in Jinek e? al, SCIENCE 2012; 337(6096):816-821.

For example, in an electrophoretic mobility shift assay, target DNA duplexes are formed by mixing of each strand (10 nmol) in deionized water, heating to 95°C for 3 min and slow cooling to room temperature. All DNAs are purified on 8% native gels containing IX TBE. DNA bands are visualized by UV shadowing, excised, and eluted by soaking gel pieces in DEPC-treated H ₂ 0. Eluted DNA is ethanol precipitated and dissolved in DEPC-treated H ₂ 0. DNA samples are 5' end labeled with [γ-32Ρ]-ΑΤΡ using T4 polynucleotide kinase for 30 min at 37°C. Polynucleotide kinase is heat denatured at 65°C for 20 min, and unincorporated radiolabel is removed using a column. Binding assays are performed in buffer containing 20 mM HEPES pH 7.5, 100 mM KC1, 5 mM MgCl ₂ , 1 mM DTT and 10% glycerol in a total volume of 10 μΐ. Cas9 protein molecule is programmed with equimolar amounts of pre-annealed gRNA molecule and titrated from 100 pM to 1 μΜ. Radiolabeled DNA is added to a final concentration of 20 pM. Samples are incubated for 1 h at 37°C and resolved at 4°C on an 8% native polyacrylamide gel containing IX TBE and 5 mM MgCl ₂ . Gels are dried and DNA visualized by phosphorimaging. Differential Scanning Flourimetry (DSF

The thermostability of Cas9-gRNA ribonucleoprotein (RNP) complexes can be measured via DSF. This technique measures the thermostability of a protein, which can increase under favorable conditions such as the addition of a binding RNA molecule, e.g., a gRNA.

The assay is performed using two different protocols, one to test the best stoichiometric ratio of gRNA:Cas9 protein and another to determine the best solution conditions for RNP formation.

To determine the best solution to form RNP complexes, a 2uM solution of Cas9 in water+10x SYPRO Orange® (Life Techonologies cat#S-6650) and dispensed into a 384 well plate. An equimolar amount of gRNA diluted in solutions with varied pH and salt is then added. After incubating at room temperature for lO'and brief centrifugation to remove any bubbles,a Bio-Rad CFX384™ Real-Time System CI 000 Touch™ Thermal Cycler with the Bio-Rad CFX Manager software is used to run a gradient from 20°C to 90°C with a 1° increase in temperature every lOseconds.

The second assay consists of mixing various concentrations of gRNA with 2uM Cas9 in optimal buffer from assay 1 above and incubating at RT for 10' in a 384 well plate. An equal volume of optimal buffer + lOx SYPRO Orange® (Life Techonologies cat#S-6650) is added and the plate sealed with Microseal® B adhesive (MSB- 1001). Following brief centrifugation to remove any bubbles, a Bio-Rad CFX384™ Real-Time System CI 000 Touch™ Thermal Cycler with the Bio-Rad CFX Manager software is used to run a gradient from 20°C to 90°C with a 1° increase in temperature every lOseconds. V. Genome Editing Approaches

In general, it is to be understood that the alteration of any gene according to the methods described herein can be mediated by any mechanism and that any methods are not limited to a particular mechanism. Exemplary mechanisms that can be associated with the alteration of a gene include, but are not limited to, non-homologous end joining (e.g., classical or alternative), microhomology-mediated end joining (MMEJ), homology-directed repair (e.g., endogenous donor template mediated), SDSA (synthesis dependent strand annealing), single strand annealing or single strand invasion. Described herein are exemplary methods for targeted knockout of one or both alleles of the FAS, BID, CTLA4, PDCD 1 , CBLB or, PTPN66, TRAC or TRBC gene using NHEJ (see Section V.1). In another embodiment, exemplary methods are provided for targeted knockdown of the FAS, BID, CTLA4, PDCD1, CBLB, or PTPN6 gene (see Section V.2). It is further contemplated that the disclosed methods may target two or more of the FAS, BID, CTLA4, PDCD1, CBLB, or PTPN6 genes for knockdown or knockout or a combination thereof.

V.l NHEJ Approaches for Gene Targeting

As described herein, nuc lease-induced non-homologous end-joining (NHEJ) can be used to target gene-specific knockouts. Nuclease-induced NHEJ can also be used to remove (e.g., delete) sequence insertions in a gene of interest.

While not wishing to be bound by theory, it is believed that, in an embodiment, the genomic alterations associated with the methods described herein rely on nuclease-induced NHEJ and the error- prone nature of the NHEJ repair pathway. NHEJ repairs a double-strand break in the DNA by joining together the two ends; however, generally, the original sequence is restored only if two compatible ends, exactly as they were formed by the double-strand break, are perfectly ligated. The DNA ends of the double-strand break are frequently the subject of enzymatic processing, resulting in the addition or removal of nucleotides, at one or both strands, prior to rejoining of the ends. This results in the presence of insertion and/or deletion (indel) mutations in the DNA sequence at the site of the NHEJ repair. Two- thirds of these mutations typically alter the reading frame and, therefore, produce a non- functional protein. Additionally, mutations that maintain the reading frame, but which insert or delete a significant amount of sequence, can destroy functionality of the protein. This is locus dependent as mutations in critical functional domains are likely less tolerable than mutations in non-critical regions of the protein. The indel mutations generated by NHEJ are unpredictable in nature; however, at a given break site certain indel sequences are favored and are over represented in the population, likely due to small regions of microhomology. The lengths of deletions can vary widely; most commonly in the 1-50 bp range, but they can easily reach greater than 100-200 bp. Insertions tend to be shorter and often include short duplications of the sequence immediately surrounding the break site. However, it is possible to obtain large insertions, and in these cases, the inserted sequence has often been traced to other regions of the genome or to plasmid DNA present in the cells.

Because NHEJ is a mutagenic process, it can also be used to delete small sequence motifs as long as the generation of a specific final sequence is not required. If a double-strand break is targeted near to a short target sequence, the deletion mutations caused by the NHEJ repair often span, and therefore remove, the unwanted nucleotides. For the deletion of larger DNA segments, introducing two double-strand breaks, one on each side of the sequence, can result in NHEJ between the ends with removal of the entire intervening sequence. Both of these approaches can be used to delete specific DNA sequences; however, the error-prone nature of NHEJ may still produce indel mutations at the site of repair.

Both double strand cleaving eaCas9 molecules and single strand, or nickase, eaCas9 molecules can be used in the methods and compositions described herein to generate NHEJ-mediated indels. NHEJ- mediated indels targeted to the gene, e.g., a coding region, e.g., an early coding region of a gene, of interest can be used to knockout (i.e., eliminate expression of) a gene of interest. For example, early coding region of a gene of interest includes sequence immediately following a transcription start site, within a first exon of the coding sequence, or within 500 bp of the transcription start site (e.g., less than 500, 450, 400, 350, 300, 250, 200, 150, 100 or 50 bp).

In an embodiment, NHEJ-mediated indels are introduced into one or more T-cell expressed genes. In an embodiment, in which a Cas9 double-stranded nuclease or a Cas9 single- stranded nickase is used to introduce mutations into two T-cell expressed genes, e.g., any two of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes, individual gRNAs or gRNA pairs targeting both genes are provided together with the Cas9 double-stranded nuclease or single-stranded nickase. In an embodiment, in which a Cas9 double-stranded nuclease or a Cas9 single- stranded nickase is used to introduce mutations into three T-cell expressed genes, e.g., any three of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes, individual gRNAs or gRNA pairs targeting all three genes are provided together with the Cas9 double-stranded nuclease or single-stranded nickase. In an embodiment, in which a Cas9 double-stranded nuclease or a Cas9 single-stranded nickase is used to introduce mutations into four T-cell expressed genes, e.g., any four of FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC genes, individual gRNAs or gRNA pairs targeting all four genes are provided together with the Cas9 double- stranded nuclease or single-stranded nickase. In an embodiment, in which a Cas9 double-stranded nuclease or a Cas9 single- stranded nickase is used to introduce mutations into five T-cell expressed genes, e.g., any five of FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC genes, individual gRNAs or gRNA pairs targeting all five genes are provided together with the Cas9 double-stranded nuclease or single-stranded nickase. In an embodiment, in which a Cas9 double-stranded nuclease or a Cas9 single- stranded nickase is used to introduce mutations into six T-cell expressed genes, e.g., any six of FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC genes, individual gRNAs or gRNA pairs targeting all six genes are provided together with the Cas9 double-stranded nuclease or single-stranded nickase. In an embodiment, in which a Cas9 double-stranded nuclease or a Cas9 single- stranded nickase is used to introduce mutations into seven T-cell expressed genes, e.g., any seven of FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC genes, individual gRNAs or gRNA pairs targeting all seven genes are provided together with the Cas9 double-stranded nuclease or single-stranded nickase. In an embodiment, in which a Cas9 double-stranded nuclease or aCas9 single-stranded nickase is used to introduce mutations into eight T-cell expressed genes, e.g., each of FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC and TRBC genes, individual gRNAs or gRNA pairs targeting all eight genes are provided together with the Cas9 double-stranded nuclease or single-stranded nickase.

Placement of double strand or single strand breaks relative to the target position

In an embodiment, in which a gRNA and Cas9 nuclease generate a double strand break for the purpose of inducing NHEJ-mediated indels, a gRNA, e.g., a unimolecular (or chimeric) or modular gRNA molecule, is configured to position one double-strand break in close proximity to a nucleotide of the target position. In an embodiment, the cleavage site is between 0-30 bp away from the target position (e.g., less than 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 bp from the target position).

In an embodiment, in which two gRNAs complexing with Cas9 nickases induce two single strand breaks for the purpose of inducing NHEJ-mediated indels, two gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to position two single-strand breaks to provide for NHEJ repair a nucleotide of the target position. In an embodiment, the gRNAs are configured to position cuts at the same position, or within a few nucleotides of one another, on different strands, essentially mimicking a double strand break. In an embodiment, the closer nick is between 0-30 bp away from the target position (e.g., less than 30, 25, 20, 15, 10, 9, 8, 7, 6, 5, 4, 3, 2 or 1 bp from the target position), and the two nicks are within 25-55 bp of each other (e.g., between 25 to 50, 25 to 45, 25 to 40, 25 to 35, 25 to 30, 50 to 55, 45 to 55, 40 to 55, 35 to 55, 30 to 55, 30 to 50, 35 to 50, 40 to 50 , 45 to 50, 35 to 45, or 40 to 45 bp) and no more than 100 bp away from each other (e.g., no more than 90, 80, 70, 60, 50, 40, 30, 20 or 10 bp). In an embodiment, the gRNAs are configured to place a single strand break on either side of a nucleotide of the target position. Both double strand cleaving eaCas9 molecules and single strand, or nickase, eaCas9 molecules can be used in the methods and compositions described herein to generate breaks both sides of a target position. Double strand or paired single strand breaks may be generated on both sides of a target position to remove the nucleic acid sequence between the two cuts (e.g., the region between the two breaks in deleted). In an embodiment, two gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to position a double-strand break on both sides of a target position. In an alternate embodiment, three gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to position a double strand break (i.e., one gRNA complexes with a cas9 nuclease) and two single strand breaks or paired single stranded breaks (i.e., two gRNAs complex with Cas9 nickases) on either side of the target position. In another embodiment, four gRNAs, e.g., independently, unimolecular (or chimeric) or modular gRNA, are configured to generate two pairs of single stranded breaks (i.e., two pairs of two gRNAs complex with Cas9 nickases) on either side of the target position. The double strand break(s) or the closer of the two single strand nicks in a pair will ideally be within 0-500 bp of the target position (e.g., no more than 450, 400, 350, 300, 250, 200, 150, 100, 50 or 25 bp from the target position). When nickases are used, the two nicks in a pair are within 25-55 bp of each other (e.g., between 25 to 50, 25 to 45, 25 to 40, 25 to 35, 25 to 30, 50 to 55, 45 to 55, 40 to 55, 35 to 55, 30 to 55, 30 to 50, 35 to 50, 40 to 50 , 45 to 50, 35 to 45, or 40 to 45 bp) and no more than 100 bp away from each other (e.g., no more than 90, 80, 70, 60, 50, 40, 30, 20 or 10 bp). V.2 Targeted Knockdown

Unlike CRISPR/Cas-mediated gene knockout, which permanently eliminates or reduces expression by mutating the gene at the DNA level, CRISPR/Cas knockdown allows for temporary reduction of gene expression through the use of artificial transcription factors. Mutating key residues in both DNA cleavage domains of the Cas9 protein (e.g., the D10A and H840A mutations) results in the generation of a catalytically inactive Cas9 (eiCas9 which is also known as dead Cas9 or dCas9). A catalytically inactive Cas9 complexes with a gRNA and localizes to the DNA sequence specified by that gRNA's targeting domain, however, it does not cleave the target DNA. Fusion of the dCas9 to an effector domain, e.g., a transcription repression domain, enables recruitment of the effector to any DNA site specified by the gRNA. While it has been shown that the eiCas9 itself can block transcription when recruited to early regions in the coding sequence, more robust repression can be achieved by fusing a transcriptional repression domain (for example KRAB, SID or ERD) to the Cas9 and recruiting it to the promoter region of a gene. It is likely that targeting DNAsel hypersensitive regions of the promoter may yield more efficient gene repression or activation because these regions are more likely to be accessible to the Cas9 protein and are also more likely to harbor sites for endogenous transcription factors. Especially for gene repression, it is contemplated herein that blocking the binding site of an endogenous transcription factor would aid in downregulating gene expression. In another embodiment, an eiCas9 can be fused to a chromatin modifying protein. Altering chromatin status can result in decreased expression of the target gene.

In an embodiment, a gRNA molecule can be targeted to a known transcription response elements

(e.g., promoters, enhancers, etc.), a known upstream activating sequences (UAS), and/or sequences of unknown or known function that are suspected of being able to control expression of the target DNA.

CRISPR/Cas-mediated gene knockdown can be used to reduce expression of an unwanted allele or transcript. Contemplated herein are scenarios wherein permanent destruction of the gene is not ideal. In these scenarios, site-specific repression may be used to temporarily reduce or eliminate expression. It is also contemplated herein that the off-target effects of a Cas-repressor may be less severe than those of a Cas-nuclease as a nuclease can cleave any DNA sequence and cause mutations whereas a Cas-repressor may only have an effect if it targets the promoter region of an actively transcribed gene. However, while nuclease-mediated knockout is permanent, repression may only persist as long as the Cas-repressor is present in the cells. Once the repressor is no longer present, it is likely that endogenous transcription factors and gene regulatory elements would restore expression to its natural state.

In an embodiment, CRISPR/Cas-mediated gene knockdown can be used to reduce expression one or more T-cell expressed genes. In an embodiment, in which a eiCas9 or an eiCas9 fusion protein described herein is used to knockdown two T-cell expressed genes, e.g., any two of FAS, BID, CTLA4, PDCDl, CBLB, or PTPN6 genes, individual gRNAs or gRNA pairs targeting both genes are provided together with the eiCas9 or eiCas9 fusion protein. In an embodiment, in which a eiCas9 or eiCas9 fusion protein is used to knockdown three T-cell expressed genes, e.g., any three of FAS, BID, CTLA4, PDCDl, CBLB, or PTPN6 genes, individual gRNAs or gRNA pairs targeting all three genes are provided together with the eiCas9 or eiCas9 fusion protein. In an embodiment, in which a eiCas9 or eiCas9 fusion protein is used to knockdown four T-cell expressed genes, e.g., any four of FAS, BID, CTLA4, PDCDl, CBLB, or PTPN6 genes, individual gRNAs or gRNA pairs targeting all four genes are provided together with the eiCas9 or eiCas9 fusion protein. In an embodiment, in which a eiCas9 or eiCas9 fusion protein is used to knockdown five T-cell expressed genes, e.g., any five of FAS, BID, CTLA4, PDCDl, CBLB, or PTPN6 genes, individual gRNAs or gRNA pairs targeting all five genes are provided together with the eiCas9 or eiCas9 fusion protein. In an embodiment, in which a eiCas9 or eiCas9 fusion protein is used to knockdown six T-cell expressed genes, e.g., each of FAS, BID, CTLA4, PDCDl, CBLB, or PTPN6 genes, individual gRNAs or gRNA pairs targeting all six genes are provided together with the eiCas9 or eiCas9 fusion protein. V.3 Single-Strand Annealing

Single strand annealing (SSA) is another DNA repair process that repairs a double-strand break between two repeat sequences present in a target nucleic acid. Repeat sequences utilized by the SSA pathway are generally greater than 30 nucleotides in length. Resection at the break ends occurs to reveal repeat sequences on both strands of the target nucleic acid. After resection, single strand overhangs containing the repeat sequences are coated with RPA protein to prevent the repeats sequences from inappropriate annealing, e.g., to themselves. RAD52 binds to and each of the repeat sequences on the overhangs and aligns the sequences to enable the annealing of the complementary repeat sequences. After annealing, the single-strand flaps of the overhangs are cleaved. New DNA synthesis fills in any gaps, and ligation restores the DNA duplex. As a result of the processing, the DNA sequence between the two repeats is deleted. The length of the deletion can depend on many factors including the location of the two repeats utilized, and the pathway or processivity of the resection.

In contrast to HDR pathways, SSA does not require a template nucleic acid to alter or correct a target nucleic acid sequence. Instead, the complementary repeat sequence is utilized.

V.4 Other DNA Repair Pathways

SSBR (single strand break repair)

Single-stranded breaks (SSB) in the genome are repaired by the SSBR pathway, which is a distinct mechanism from the DSB repair mechanisms discussed above. The SSBR pathway has four major stages: SSB detection, DNA end processing, DNA gap filling, and DNA ligation. A more detailed explanation is given in Caldecott, Nature Reviews Genetics 9, 619-631 (August 2008), and a summary is given here.

In the first stage, when a SSB forms, PARP1 and/or PARP2 recognize the break and recruit repair machinery. The binding and activity of PARPl at DNA breaks is transient and it seems to accelerate

SSBr by promoting the focal accumulation or stability of SSBr protein complexes at the lesion. Arguably the most important of these SSBr proteins is XRCC1, which functions as a molecular scaffold that interacts with, stabilizes, and stimulates multiple enzymatic components of the SSBr process including the protein responsible for cleaning the DNA 3' and 5' ends. For instance, XRCC1 interacts with several proteins (DNA polymerase beta, PNK, and three nucleases, APE1, APTX, and APLF) that promote end processing. APE1 has endonuclease activity. APLF exhibits endonuclease and 3' to 5' exonuc lease activities. APTX has endonuclease and 3' to 5' exonuclease activity.

This end processing is an important stage of SSBR since the 3'- and/or 5 '-termini of most, if not all, SSBs are 'damaged'. End processing generally involves restoring a damaged 3 '-end to a hydroxylated state and and/or a damaged 5' end to a phosphate moiety, so that the ends become ligation-competent. Enzymes that can process damaged 3' termini include PNKP, APE1, and TDP1. Enzymes that can process damaged 5' termini include PNKP, DNA polymerase beta, and APTX. LIG3 (DNA ligase III) can also participate in end processing. Once the ends are cleaned, gap filling can occur.

At the DNA gap filling stage, the proteins typically present are PARP1, DNA polymerase beta,

XRCC1, FEN1 (flap endonculease 1), DNA polymerase delta/epsilon, PCNA, and LIG1. There are two ways of gap filling, the short patch repair and the long patch repair. Short patch repair involves the insertion of a single nucleotide that is missing. At some SSBs, "gap filling" might continue displacing two or more nucleotides (displacement of up to 12 bases have been reported). FEN1 is an endonuc lease that removes the displaced 5'-residues. Multiple DNA polymerases, including Pol β , are involved in the repair of SSBs, with the choice of DNA polymerase influenced by the source and type of SSB.

In the fourth stage, a DNA ligase such as LIG1 (Ligase I) or LIG3 (Ligase III) catalyzes joining of the ends. Short patch repair uses Ligase III and long patch repair uses Ligase I.

Sometimes, SSBR is replication-coupled. This pathway can involve one or more of CtIP, MRN, ERCC 1 , and FEN 1. Additional factors that may promote SSBR include: aPARP, PARP 1 , PARP2, PARG, XRCC1, DNA polymerase b, DNA polymerase d, DNA polymerase e, PCNA, LIG1, PNK, PNKP, APE1, APTX, APLF, TDP1, LIG3, FEN1, CtIP, MRN, and ERCC1.

MMR (mismatch repair)

Cells contain three excision repair pathways: MMR, BER, and NER. The excision repair pathways hace a common feature in that they typically recognize a lesion on one strand of the DNA, then exo/endonucleaseases remove the lesion and leave a 1-30 nucleotide gap that is sub-sequentially filled in by DNA polymerase and finally sealed with ligase. A more complete picture is given in Li, Cell Research (2008) 18:85-98, and a summary is provided here.

Mismatch repair (MMR) operates on mispaired DNA bases.

The MSH2/6 or MSH2/3 complexes both have ATPases activity that plays an important role in mismatch recognition and the initiation of repair. MSH2/6 preferentially recognizes base-base mismatches and identifies mispairs of 1 or 2 nucleotides, while MSH2/3 preferentially recognizes larger ID mispairs.

hMLHl heterodimerizes with hPMS2 to form hMutL a which possesses an ATPase activity and is important for multiple steps of MMR. It possesses a PCNA/replication factor C (RFC)-dependent endonuclease activity which plays an important role in 3 ' nick-directed MMR involving EXOl . (EXOl is a participant in both HR and MMR.) It regulates termination of mismatch-provoked excision. Ligase I is the relevant ligase for this pathway. Additional factors that may promote MMR include: EXO l, MSH2, MSH3, MSH6, MLH1, PMS2, MLH3, DNA Pol d, RPA, HMGB 1, RFC, and DNA ligase I.

Base excision repair (BER)

The base excision repair (BER) pathway is active throughout the cell cycle; it is responsible primarily for removing small, non-helix-distorting base lesions from the genome. In contrast, the related Nucleotide Excision Repair pathway (discussed in the next section) repairs bulky helix-distorting lesions. A more detailed explanation is given in Caldecott, Nature Reviews Genetics 9, 619-631 (August 2008), and a summary is given here.

Upon DNA base damage, base excision repair (BER) is initiated and the process can be simplified into five major steps: (a) removal of the damaged DNA base; (b) incision of the subsequent a basic site; (c) clean-up of the DNA ends; (d) insertion of the correct nucleotide into the repair gap; and (e) ligation of the remaining nick in the DNA backbone. These last steps are similar to the SSBR.

In the first step, a damage-specific DNA glycosylase excises the damaged base through cleavage of the N-glycosidic bond linking the base to the sugar phosphate backbone. Then AP endonuclease- 1 (APE1) or bifunctional DNA glycosylases with an associated lyase activity incised the phosphodiester backbone to create a DNA single strand break (SSB). The third step of BER involves cleaning-up of the DNA ends. The fourth step in BER is conducted by Pol β that adds a new complementary nucleotide into the repair gap and in the final step XRCC1 /Ligase III seals the remaining nick in the DNA backbone. This completes the short-patch BER pathway in which the majority (-80%) of damaged DNA bases are repaired. However, if the 5' -ends in step 3 are resistant to end processing activity, following one nucleotide insertion by Pol β there is then a polymerase switch to the replicative DNA polymerases, Pol δ/ε, which then add ~2-8 more nucleotides into the DNA repair gap. This creates a 5' -flap structure, which is recognized and excised by flap endonuclease- 1 (FEN-1) in association with the processivity factor proliferating cell nuclear antigen (PCNA). DNA ligase I then seals the remaining nick in the DNA backbone and completes long-patch BER. Additional factors that may promote the BER pathway include: DNA glycosylase, APE1, Polb, Pold, Pole, XRCC1, Ligase III, FEN-1, PCNA, RECQL4, WRN, MYH, PNKP, and APTX. Nucleotide excision repair (NER)

Nucleotide excision repair (NER) is an important excision mechanism that removes bulky helix- distorting lesions from DNA. Additional details about NER are given in Marteijn et al., Nature Reviews Molecular Cell Biology 15, 465-481 (2014), and a summary is given here. NER a broad pathway encompassing two smaller pathways: global genomic NER (GG-NER) and transcription coupled repair NER (TC-NER). GG-NER and TC-NER use different factors for recognizing DNA damage. However, they utilize the same machinery for lesion incision, repair, and ligation.

Once damage is recognized, the cell removes a short single-stranded DNA segment that contains the lesion. Endonuc leases XPF/ERCCl and XPG (encoded by ERCC5) remove the lesion by cutting the damaged strand on either side of the lesion, resulting in a single-strand gap of 22-30 nucleotides. Next, the cell performs DNA gap filling synthesis and ligation. Involved in this process are: PCNA, RFC, DNA Pol δ, DNA Pol ε or DNA Pol κ, and DNA ligase I or XRCCl/Ligase III. Replicating cells tend to use DNA pol ε and DNA ligase I, while non-replicating cells tend to use DNA Pol δ, DNA Pol κ, and the XRCC1/ Ligase III complex to perform the ligation step.

NER can involve the following factors : XPA-G, POLH, XPF, ERCC 1 , XPA-G, and LIG 1.

Transcription-coupled NER (TC-NER) can involve the following factors: CSA, CSB, XPB, XPD, XPG, ERCC 1 , and TTDA. Additional factors that may promote the NER repair pathway include XPA-G, POLH, XPF, ERCC1, XPA-G, LIG1, CSA, CSB, XPA, XPB, XPC, XPD, XPF, XPG, TTDA, UVSSA, USP7, CETN2, RAD23B, UV-DDB, CAK subcomplex, RPA, and PCNA.

Interstrand Crosslink (ICL)

A dedicated pathway called the ICL repair pathway repairs interstrand crosslinks. Interstrand crosslinks, or covalent crosslinks between bases in different DNA strand, can occur during replication or transcription. ICL repair involves the coordination of multiple repair processes, in particular, nucleolytic activity, translesion synthesis (TLS), and HDR. Nucleases are recruited to excise the ICL on either side of the crosslinked bases, while TLS and HDR are coordinated to repair the cut strands. ICL repair can involve the following factors: endonucleases, e.g., XPF and RAD51C, endonucleases such as RAD51, translesion polymerases, e.g., DNA polymerase zeta and Revl), and the Fanconi anemia (FA) proteins, e.g., FancJ.

Other pathways

Several other DNA repair pathways exist in mammals.

Translesion synthesis (TLS) is a pathway for repairing a single stranded break left after a defective replication event and involves translesion polymerases, e.g., DNA ροΐζ and Revl .

Error- free postreplication repair (PRR) is another pathway for repairing a single stranded break left after a defective replication event.

V.5 Examples of gRNAs in Genome Editing Methods gR A molecules as described herein can be used with Cas9 molecules that generate a double strand break or a single strand break to alter the sequence of a target nucleic acid, e.g., a target position or target genetic signature. gRNA molecules useful in these methods are described below.

Cas9 molecules and gRNA molecules, e.g., a Cas9 molecule/gRNA molecule complex, can be used to manipulate a cell, e.g., to edit a target nucleic acid, in a wide variety of cells.

In an embodiment, a cell is manipulated by editing (e.g., inducing a mutation in) one or more target genes, e.g., as described herein. In some embodiments, the expression of one or more target genes (e.g., FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC gene) is modulated. In another embodiment, a cell is manipulated ex vivo by editing (e.g., inducing a mutation in) one or more target genes and/or modulating the expression of one or more target genes, e.g., FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC gene, and administered to a subject. Sources of target cells for ex vivo manipulation may include, e.g., the subject's blood, the subject's cord blood, or the subject's bone marrow. Sources of target cells for ex vivo manipulation may also include, e.g., heterologous donor blood, cord blood, or bone marrow.

The Cas9 and gRNA molecules described herein can be delivered to a target cell. In an embodiment, the target cell is a T cell, e.g., a CD8+ T cell (e.g., a CD8+ naive T cell, central memory T cell, or effector memory T cell), a CD4+ T cell, a natural killer T cell (NKT cells), a regulatory T cell (Treg), a stem cell memory T cell, a lymphoid progenitor cell a hematopoietic stem cell, a natural killer cell (NK cell) or a dendritic cell. In an embodiment, the target cell is an induced pluripotent stem (iPS) cell or a cell derived from an iPS cell, e.g., an iPS cell generated from a subject, manipulated to alter (e.g., induce a mutation in) or manipulate the expression of one or more target genes, e.g., FAS, BID, CTLA4, PDCDl, CBLB, PTPN6, TRAC or TRBC gene, and differentiated into, e.g., a T cell, e.g., a CD8+ T cell (e.g., a CD8+ naive T cell, central memory T cell, or effector memory T cell), a CD4+ T cell, a stem cell memory T cell, a lymphoid progenitor cell or a hematopoietic stem cell.

VII. Ex Vivo Delivery of Components to Target Cells

The components, e.g., a Cas9 molecule and gRNA molecule can be introduced into target cells in a variety of forms using a variety of delivery methods and formulations, see, e.g., Tables 700 and 800. When a Cas9 or gRNA component is encoded as DNA for delivery, the DNA may typically but not necessarily include a control region, e.g., comprising a promoter, to effect expression. Useful promoters for Cas9 molecule sequences include, e.g., CMV, EF- l a, EFS, MSCV, PGK, or CAG promoters. Useful promoters for gRNAs include, e.g., HI , EF- l a, tRNA or U6 promoters. Promoters with similar or dissimilar strengths can be selected to tune the expression of components. Sequences encoding a Cas9 molecule may comprise a nuclear localization signal (NLS), e.g., an SV40 NLS. In an embodiment a promoter for a Cas9 molecule or a gRNA molecule may be, independently, inducible, tissue specific, or cell specific.

Table 700 provides examples of the form in which the components can be delivered to a target cell.

DNA-based Delivery of a Cas9 molecule and/or a gRNA molecule

DNA encoding Cas9 molecules (e.g., eaCas9 molecules) and/or gRNA molecules, can be delivered into cells by art-known methods or as described herein. For example, Cas9-encoding and/or gRNA-encoding DNA can be delivered, e.g., by vectors (e.g., viral or non-viral vectors), non-vector based methods (e.g., using naked DNA or DNA complexes), or a combination thereof.

In some embodiments, the Cas9- and/or gRNA-encoding DNA is delivered by a vector (e.g., viral vector/virus or plasmid).

A vector may comprise a sequence that encodes a Cas9 molecule and/or a gRNA molecule. A vector may also comprise a sequence encoding a signal peptide (e.g., for nuclear localization, nucleolar localization, mitochondrial localization), fused, e.g., to a Cas9 molecule sequence. For example, a vector may comprise a nuclear localization sequence (e.g., from SV40) fused to the sequence encoding the Cas9 molecule.

One or more regulatory/control elements, e.g., a promoter, an enhancer, an intron, a

polyadenylation signal, a Kozak consensus sequence, internal ribosome entry sites (IRES), a 2A sequence, and splice acceptor or donor can be included in the vectors. In an embodiment, the promoter is recognized by RNA polymerase II (e.g., a CMV promoter). In another embodiment, the promoter is recognized by RNA polymerase III (e.g., a U6 promoter). In another embodiment, the promoter is a regulated promoter (e.g., inducible promoter). In another embodiment, the promoter is a constitutive promoter. In another embodiment, the promoter is a tissue specific promoter. In another embodiment, the promoter is a viral promoter. In another embodiment, the promoter is a non- viral promoter.

In an embodiment, the vector or delivery vehicle is a viral vector (e.g., for generation of recombinant viruses). In an embodiment, the virus is a DNA virus (e.g., dsDNA or ssDNA virus). In an embodiment, the virus is an RNA virus (e.g., an ssRNA virus). Exemplary viral vectors/viruses include, e.g., retroviruses, lentiviruses, adenovirus, adeno-associated virus (AAV), vaccinia viruses, poxviruses, and herpes simplex viruses.

In an embodiment, the virus infects dividing cells. In another embodiment, the virus infects non- dividing cells. In another embodiment, the virus infects both dividing and non-dividing cells. In another embodiment, the virus can integrate into the host genome. In another embodiment, the virus is engineered to have reduced immunity, e.g., in human. In another embodiment, the virus is replication- competent. In another embodiment, the virus is replication-defective, e.g., having one or more coding regions for the genes necessary for additional rounds of virion replication and/or packaging replaced with other genes or deleted. In another embodiment, the virus causes transient expression of the Cas9 molecule and/or the gRNA molecule. In another embodiment, the virus causes long-lasting, e.g., at least 1 week, 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 1 year, 2 years, or permanent expression, of the Cas9 molecule and/or the gRNA molecule. The packaging capacity of the viruses may vary, e.g., from at least about 4 kb to at least about 30 kb, e.g., at least about 5 kb, 10 kb, 15 kb, 20 kb, 25 kb, 30 kb, 35 kb, 40 kb, 45 kb, or 50 kb.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant retrovirus. In another embodiment, the retrovirus (e.g., Moloney murine leukemia virus) comprises a reverse transcriptase, e.g., that allows integration into the host genome. In an embodiment, the retrovirus is replication-competent. In another embodiment, the retrovirus is replication-defective, e.g., having one of more coding regions for the genes necessary for additional rounds of virion replication and packaging replaced with other genes, or deleted.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant lentivirus. For example, the lentivirus is replication-defective, e.g., does not comprise one or more genes required for viral replication.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant adenovirus. In another embodiment, the adenovirus is engineered to have reduced immunity in humans.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a recombinant AAV.

In an embodiment, the AAV can incorporate its genome into that of a host cell, e.g., a target cell as described herein. In another embodiment, the AAV is a self-complementary adeno-associated virus (scAAV), e.g., a scAAV that packages both strands which anneal together to form double stranded DNA. AAV serotypes that may be used in the disclosed methods, include AAVl, AAV2, modified AAV2 (e.g., modifications at Y444F, Y500F, Y730F and/or S662V), AAV3, modified AAV3 (e.g., modifications at Y705F, Y731F and/or T492V), AAV4, AAV5, AAV6, modified AAV6 (e.g., modifications at S663V and/or T492V), AAV8, AAV 8.2, AAV9, AAV rh 10, and pseudotyped AAV, such as AAV2/8, AAV2/5 and AAV2/6 can also be used in the disclosed methods.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a hybrid virus, e.g., a hybrid of one or more of the viruses described herein.

A packaging cell is used to form a virus particle that is capable of infecting a target cell. Such a cell includes a 293 cell, which can package adenovirus, and a ψ2 cell or a PA317 cell, which can package retrovirus. A viral vector used in gene therapy is usually generated by a producer cell line that packages a nucleic acid vector into a viral particle. The vector typically contains the minimal viral sequences required for packaging and subsequent integration into a host or target cell (if applicable), with other viral sequences being replaced by an expression cassette encoding the protein to be expressed, eg. Cas9. For example, an AAV vector used in gene therapy typically only possesses inverted terminal repeat (ITR) sequences from the AAV genome which are required for packaging and gene expression in the host or target cell. The missing viral functions are supplied in trans by the packaging cell line. Henceforth, the viral DNA is packaged in a cell line, which contains a helper plasmid encoding the other AAV genes, namely rep and cap, but lacking ITR sequences. The cell line is also infected with adenovirus as a helper. The helper virus promotes replication of the AAV vector and expression of AAV genes from the helper plasmid. The helper plasmid is not packaged in significant amounts due to a lack of ITR sequences. Contamination with adenovirus can be reduced by, e.g., heat treatment to which adenovirus is more sensitive than AAV.

In an embodiment, the viral vector has the ability of cell type recognition. For example, the viral vector can be pseudotyped with a different/alternative viral envelope glycoprotein; engineered with a cell type-specific receptor (e.g., genetic modification of the viral envelope glycoproteins to incorporate targeting ligands such as a peptide ligand, a single chain antibody, a growth factor); and/or engineered to have a molecular bridge with dual specificities with one end recognizing a viral glycoprotein and the other end recognizing a moiety of the target cell surface (e.g., ligand-receptor, monoclonal antibody, avidin-biotin and chemical conjugation).

In an embodiment, the viral vector achieves cell type specific expression. For example, a tissue- specific promoter can be constructed to restrict expression of the transgene (Cas 9 and gRNA) in only a specific target cell. The specificity of the vector can also be mediated by microRNA-dependent control of transgene expression. In an embodiment, the viral vector has increased efficiency of fusion of the viral vector and a target cell membrane. For example, a fusion protein such as fusion-competent

hemagglutinin (HA) can be incorporated to increase viral uptake into cells. In an embodiment, the viral vector has the ability of nuclear localization. For example, a virus that requires the breakdown of the nuclear membrane (during cell division) and therefore will not infect a non-diving cell can be altered to incorporate a nuclear localization peptide in the matrix protein of the virus thereby enabling the transduction of non-proliferating cells.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a non-vector based method (e.g., using naked DNA or DNA complexes). For example, the DNA can be delivered, e.g., by organically modified silica or silicate (Ormosil), electroporation, transient cell compression or squeezing (eg, as described in Lee, et al [2012] Nano Lett 12: 6322-27), gene gun, sonoporation, magnetofection, lipid-mediated transfection, dendrimers, inorganic nanoparticles, calcium phosphates, or a combination thereof.

In an embodiment, delivery via electroporation comprises mixing the cells with the Cas9-and/or gRNA-encoding DNA in a cartridge, chamber or cuvette and applying one or more electrical impulses of defined duration and amplitude. In an embodiment, delivery via electroporation is performed using a system in which cells are mixed with the Cas9-and/or gRNA-encoding DNA in a vessel connected to a device (eg, a pump) which feeds the mixture into a cartridge, chamber or cuvette wherein one or more electrical impulses of defined duration and amplitude are applied, after which the cells are delivered to a second vessel.

In an embodiment, the Cas9- and/or gRNA-encoding DNA is delivered by a combination of a vector and a non-vector based method. For example, a virosome comprises a liposome combined with an inactivated virus (e.g., HIV or influenza virus), which can result in more efficient gene transfer than either a viral or a liposomal method alone.

In an embodiment, the delivery vehicle is a non- viral vector. In an embodiment, the non- viral vector is an inorganic nanoparticle. Exemplary inorganic nanoparticles include, e.g., magnetic nanoparticles (e.g., FesMnC^) and silica. The outer surface of the nanoparticle can be conjugated with a positively charged polymer (e.g., polyethylenimine, polylysine, polyserine) which allows for attachment (e.g., conjugation or entrapment) of payload. In an embodiment, the non-viral vector is an organic nanoparticle. Exemplary organic nanoparticles include, e.g., SNALP liposomes that contain cationic lipids together with neutral helper lipids which are coated with polyethylene glycol (PEG), and protamine-nucleic acid complexes coated with lipid.

Exemplary lipids for gene transfer are shown below in Table 900.

Dextran-spermine D-SPM In an embodiment, the vehicle has targeting modifications to increase target cell update of nanoparticles and liposomes, e.g., cell specific antigens, monoclonal antibodies, single chain antibodies, aptamers, polymers, sugars, and cell penetrating peptides. In an embodiment, the vehicle uses fusogenic and endosome-destabilizing peptides/polymers. In an embodiment, the vehicle undergoes acid-triggered conformational changes (e.g., to accelerate endosomal escape of the cargo). In an embodiment, a stimulus-cleavable polymer is used, e.g., for release in a cellular compartment. For example, disulfide - based cationic polymers that are cleaved in the reducing cellular environment can be used.

In an embodiment, the delivery vehicle is a biological non- viral delivery vehicle. In an embodiment, the vehicle is an attenuated bacterium (e.g., naturally or artificially engineered to be invasive but attenuated to prevent pathogenesis and expressing the transgene (e.g., Listeria

monocytogenes, certain Salmonella strains, Bifidobacterium longum, and modified Escherichia coli), bacteria having nutritional and tissue-specific tropism to target specific cells, bacteria having modified surface proteins to alter target cell specificity). In an embodiment, the vehicle is a genetically modified bacteriophage (e.g., engineered phages having large packaging capacity, less immunogenicity, containing mammalian plasmid maintenance sequences and having incorporated targeting ligands). In an embodiment, the vehicle is a mammalian virus-like particle. For example, modified viral particles can be generated (e.g., by purification of the "empty" particles followed by ex vivo assembly of the virus with the desired cargo). The vehicle can also be engineered to incorporate targeting ligands to alter target tissue specificity. In an embodiment, the vehicle is a biological liposome. For example, the biological liposome is a phospholipid-based particle derived from human cells (e.g., erythrocyte ghosts, which are red blood cells broken down into spherical structures derived from the subject (e.g., tissue targeting can be achieved by attachment of various tissue or cell-specific ligands), or secretory exosomes -subject- derived membrane-bound nanovescicles (30 -100 nm) of endocytic origin (e.g., can be produced from various cell types and can therefore be taken up by cells without the need for targeting ligands).

In an embodiment, one or more nucleic acid molecules (e.g., DNA molecules) other than the components of a Cas system, e.g., the Cas9 molecule component and/or the gRNA molecule component described herein, are delivered. In an embodiment, the nucleic acid molecule is delivered at the same time as one or more of the components of the Cas system. In an embodiment, the nucleic acid molecule is delivered before or after (e.g., less than about 30 minutes, 1 hour, 2 hours, 3 hours, 6 hours, 9 hours, 12 hours, 1 day, 2 days, 3 days, 1 week, 2 weeks, or 4 weeks) one or more of the components of the Cas system are delivered. In an embodiment, the nucleic acid molecule is delivered by a different means from one or more of the components of the Cas system, e.g., the Cas9 molecule component and/or the gRNA molecule component. The nucleic acid molecule can be delivered by any of the delivery methods described herein. For example, the nucleic acid molecule can be delivered by a viral vector, e.g., a retrovirus or a lentivirus, and the Cas9 molecule component and/or the gRNA molecule component can be delivered by electroporation. In an embodiment, the nucleic acid molecule encodes a TRAC gene, a TRBC gene or a CAR gene.

Delivery of RNA encoding a Cas9 molecule

RNA encoding Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) and/or gRNA molecules, can be delivered into cells, e.g., target cells described herein, by art- known methods or as described herein. For example, Cas9-encoding and/or gRNA-encoding RNA can be delivered, e.g., by microinjection, electroporation, transient cell compression or squeezing (eg, as described in Lee, et al [2012] Nano Lett 12: 6322-27), lipid-mediated transfection, peptide-mediated delivery, or a combination thereof.

In an embodiment, delivery via electroporation comprises mixing the cells with the RNA encoding Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion protiens) and/or gRNA molecules in a cartridge, chamber or cuvette and applying one or more electrical impulses of defined duration and amplitude. In an embodiment, delivery via electroporation is performed using a system in which cells are mixed with the RNA encoding Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion protiens) and/or gRNA molecules in a vessel connected to a device (eg, a pump) which feeds the mixture into a cartridge, chamber or cuvette wherein one or more electrical impulses of defined duration and amplitude are applied, after which the cells are delivered to a second vessel.

Delivery of Cas9 molecule protein

Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) can be delivered into cells by art-known methods or as described herein. For example, Cas9 protein molecules can be delivered, e.g., by microinjection, electroporation, transient cell compression or squeezing (eg, as described in Lee, et al [2012] Nano Lett 12: 6322-27), lipid-mediated transfection, peptide-mediated delivery, or a combination thereof. Delivery can be accompanied by DNA encoding a gRNA or by a gRNA.

In an embodiment, delivery via electroporation comprises mixing the cells with the Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion proteins) with or without gRNA molecules in a cartridge, chamber or cuvette and applying one or more electrical impulses of defined duration and amplitude. In an embodiment, delivery via electroporation is performed using a system in which cells are mixed with the Cas9 molecules (e.g., eaCas9 molecules, eiCas9 molecules or eiCas9 fusion protiens) with or without gRNA molecules in a vessel connected to a device (e.g., a pump) which feeds the mixture into a cartridge, chamber or cuvette wherein one or more electrical impulses of defined duration and amplitude are applied, after which the cells are delivered to a second vessel.

VIII. Modified Nucleosides, Nucleotides, and Nucleic Acids

Modified nucleosides and modified nucleotides can be present in nucleic acids, e.g., particularly gRNA, but also other forms of RNA, e.g., mRNA, RNAi, or siRNA. As described herein, "nucleoside" is defined as a compound containing a five-carbon sugar molecule (a pentose or ribose) or derivative thereof, and an organic base, purine or pyrimidine, or a derivative thereof. As described herein,

"nucleotide" is defined as a nucleoside further comprising a phosphate group.

Modified nucleosides and nucleotides can include one or more of:

(i) alteration, e.g., replacement, of one or both of the non-linking phosphate oxygens and/or of one or more of the linking phosphate oxygens in the phosphodiester backbone linkage;

(ii) alteration, e.g., replacement, of a constituent of the ribose sugar, e.g., of the 2' hydroxyl on the ribose sugar;

(iii) wholesale replacement of the phosphate moiety with "dephospho" linkers;

(iv) modification or replacement of a naturally occurring nucleobase;

(v) replacement or modification of the ribose-phosphate backbone;

(vi) modification of the 3' end or 5' end of the oligonucleotide, e.g., removal, modification or replacement of a terminal phosphate group or conjugation of a moiety; and

(vii) modification of the sugar.

The modifications listed above can be combined to provide modified nucleosides and nucleotides that can have two, three, four, or more modifications. For example, a modified nucleoside or nucleotide can have a modified sugar and a modified nucleobase. In an embodiment, every base of a gRNA is modified, e.g., all bases have a modified phosphate group, e.g., all are phosphorothioate groups. In an embodiment, all, or substantially all, of the phosphate groups of a unimolecular or modular gRNA molecule are replaced with phosphorothioate groups.

In an embodiment, modified nucleotides, e.g., nucleotides having modifications as described herein, can be incorporated into a nucleic acid, e.g., a "modified nucleic acid." In some embodiments, the modified nucleic acids comprise one, two, three or more modified nucleotides. In some embodiments, at least 5% (e.g., at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, or about 100%) of the positions in a modified nucleic acid are a modified nucleotides. Unmodified nucleic acids can be prone to degradation by, e.g., cellular nucleases. For example, nucleases can hydrolyze nucleic acid phosphodiester bonds. Accordingly, in one aspect the modified nucleic acids described herein can contain one or more modified nucleosides or nucleotides, e.g., to introduce stability toward nucleases.

In some embodiments, the modified nucleosides, modified nucleotides, and modified nucleic acids described herein can exhibit a reduced innate immune response when introduced into a population of cells. The term "innate immune response" includes a cellular response to exogenous nucleic acids, including single stranded nucleic acids, generally of viral or bacterial origin, which involves the induction of cytokine expression and release, particularly the interferons, and cell death. In some embodiments, the modified nucleosides, modified nucleotides, and modified nucleic acids described herein can disrupt binding of a major groove interacting partner with the nucleic acid. In some embodiments, the modified nucleosides, modified nucleotides, and modified nucleic acids described herein can exhibit a reduced innate immune response when introduced into a population of cells and also disrupt binding of a major groove interacting partner with the nucleic acid.

Definitions of Chemical Groups

As used herein, "alkyl" is meant to refer to a saturated hydrocarbon group which is straight- chained or branched. Example alkyl groups include methyl (Me), ethyl (Et), propyl (e.g. , n-propyl and isopropyl), butyl (e.g., n-butyl, isobutyl, t-butyl), pentyl (e.g., n-pentyl, isopentyl, neopentyl), and the like. An alkyl group can contain from 1 to about 20, from 2 to about 20, from 1 to about 12, from 1 to about 8, from 1 to about 6, from 1 to about 4, or from 1 to about 3 carbon atoms.

As used herein, "aryl" refers to monocyclic or polycyclic (e.g. , having 2, 3 or 4 fused rings) aromatic hydrocarbons such as, for example, phenyl, naphthyl, anthracenyl, phenanthrenyl, indanyl, indenyl, and the like. In some embodiments, aryl groups have from 6 to about 20 carbon atoms.

As used herein, "alkenyl" refers to an aliphatic group containing at least one double bond.

As used herein, "alkynyl" refers to a straight or branched hydrocarbon chain containing 2- 12 carbon atoms and characterized in having one or more triple bonds. Examples of alkynyl groups include, but are not limited to, ethynyl, propargyl, and 3-hexynyl.

As used herein, "arylalkyl" or "aralkyl" refers to an alkyl moiety in which an alkyl hydrogen atom is replaced by an aryl group. Aralkyl includes groups in which more than one hydrogen atom has been replaced by an aryl group. Examples of "arylalkyl" or "aralkyl" include benzyl, 2-phenylethyl, 3- phenylpropyl, 9-fluorenyl, benzhydryl, and trityl groups. As used herein, "cycloalkyl" refers to a cyclic, bicyclic, tricyclic, or polycyclic non-aromatic hydrocarbon groups having 3 to 12 carbons. Examples of cycloalkyl moieties include, but are not limited to, cyclopropyl, cyclopentyl, and cyclohexyl.

As used herein, "heterocyclyl" refers to a monovalent radical of a heterocyclic ring system. Representative heterocyclyls include, without limitation, tetrahydrofuranyl, tetrahydrothienyl, pyrrolidinyl, pyrrolidonyl, piperidinyl, pyrrolinyl, piperazinyl, dioxanyl, dioxolanyl, diazepinyl, oxazepinyl, thiazepinyl, and morpholinyl.

As used herein, "heteroaryl" refers to a monovalent radical of a heteroaromatic ring system. Examples of heteroaryl moieties include, but are not limited to, imidazolyl, oxazolyl, thiazolyl, triazolyl, pyrrolyl, furanyl, indolyl, thiophenyl pyrazolyl, pyridinyl, pyrazinyl, pyridazinyl, pyrimidinyl, indolizinyl, purinyl, naphthyridinyl, quinolyl, and pteridinyl.

Phosphate Backbone Modifications

The Phosphate Group

In some embodiments, the phosphate group of a modified nucleotide can be modified by replacing one or more of the oxygens with a different substituent. Further, the modified nucleotide, e.g., modified nucleotide present in a modified nucleic acid, can include the wholesale replacement of an unmodified phosphate moiety with a modified phosphate as described herein. In some embodiments, the modification of the phosphate backbone can include alterations that result in either an uncharged linker or a charged linker with unsymmetrical charge distribution.

Examples of modified phosphate groups include, phosphorothioate, phosphoroselenates, borano phosphates, borano phosphate esters, hydrogen phosphonates, phosphoroamidates, alkyl or aryl phosphonates and phosphotriesters. In some embodiments, one of the non-bridging phosphate oxygen atoms in the phosphate backbone moiety can be replaced by any of the following groups: sulfur (S), selenium (Se), BR ₃ (wherein R can be, e.g., hydrogen, alkyl, or aryl), C (e.g., an alkyl group, an aryl group, and the like), H, NR ₂ (wherein R can be, e.g., hydrogen, alkyl, or aryl), or OR (wherein R can be, e.g., alkyl or aryl). The phosphorous atom in an unmodified phosphate group is achiral. However, replacement of one of the non-bridging oxygens with one of the above atoms or groups of atoms can render the phosphorous atom chiral; that is to say that a phosphorous atom in a phosphate group modified in this way is a stereogenic center. The stereogenic phosphorous atom can possess either the "R" configuration (herein Rp) or the "S" configuration (herein Sp).

Phosphorodithioates have both non-bridging oxygens replaced by sulfur. The phosphorus center in the phosphorodithioates is achiral which precludes the formation of oligoribonucleotide diastereomers. In some embodiments, modifications to one or both non-bridging oxygens can also include the replacement of the non-bridging oxygens with a group independently selected from S, Se, B, C, H, N, and OR (R can be, e.g., alkyl or aryl).

The phosphate linker can also be modified by replacement of a bridging oxygen, (i.e., the oxygen that links the phosphate to the nucleoside), with nitrogen (bridged phosphoroamidates), sulfur (bridged phosphorothioates) and carbon (bridged methylenephosphonates). The replacement can occur at either linking oxygen or at both of the linking oxygens.

Replacement of the Phosphate Group

The phosphate group can be replaced by non-phosphorus containing connectors. In some embodiments, the charge phosphate group can be replaced by a neutral moiety.

Examples of moieties which can replace the phosphate group can include, without limitation, e.g., methyl phosphonate, hydroxylamino, siloxane, carbonate, carboxymethyl, carbamate, amide, thioether, ethylene oxide linker, sulfonate, sulfonamide, thioformacetal, formacetal, oxime, methyleneimino, methylenemethylimino, methylenehydrazo, methylenedimethylhydrazo and methyleneoxymethylimino.

Replacement of the Ribophosphate Backbone

Scaffolds that can mimic nucleic acids can also be constructed wherein the phosphate linker and ribose sugar are replaced by nuclease resistant nucleoside or nucleotide surrogates. In some

embodiments, the nucleobases can be tethered by a surrogate backbone. Examples can include, without limitation, the morpholino, cyclobutyl, pyrrolidine and peptide nucleic acid (PNA) nucleoside surrogates.

Sugar Modifications

The modified nucleosides and modified nucleotides can include one or more modifications to the sugar group. For example, the 2' hydroxyl group (OH) can be modified or replaced with a number of different "oxy" or "deoxy" substituents. In some embodiments, modifications to the 2' hydroxyl group can enhance the stability of the nucleic acid since the hydroxyl can no longer be deprotonated to form a 2'-alkoxide ion. The 2'-alkoxide can catalyze degradation by intramolecular nucleophilic attack on the linker phosphorus atom.

Examples of "oxy"-2' hydroxyl group modifications can include alkoxy or aryloxy (OR, wherein "R" can be, e.g., alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or a sugar); polyethyleneglycols (PEG), 0(CH ₂ CH ₂ 0) _n CH ₂ CH ₂ OR wherein R can be, e.g., H or optionally substituted alkyl, and n can be an integer from 0 to 20 (e.g., from 0 to 4, from 0 to 8, from 0 to 10, from 0 to 16, from 1 to 4, from 1 to 8, from 1 to 10, from 1 to 16, from 1 to 20, from 2 to 4, from 2 to 8, from 2 to 10, from 2 to 16, from 2 to 20, from 4 to 8, from 4 to 10, from 4 to 16, and from 4 to 20). In some embodiments, the "oxy"-2' hydroxyl group modification can include "locked" nucleic acids (LNA) in which the 2' hydroxyl can be connected, e.g., by a Ci_6 alkylene or Ci_6 heteroalkylene bridge, to the 4' carbon of the same ribose sugar, where exemplary bridges can include methylene, propylene, ether, or amino bridges; O-amino (wherein amino can be, e.g., NH ₂ ; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroarylamino, ethylenediamine, or polyamino) and aminoalkoxy, 0(CH ₂ ) _n -amino, (wherein amino can be, e.g., NH ₂ ; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroarylamino, ethylenediamine, or polyamino). In some embodiments, the "oxy"-2' hydroxyl group modification can include the methoxyethyl group (MOE), (OCH ₂ CH ₂ OCH ₃ , e.g., a PEG derivative).

"Deoxy" modifications can include hydrogen (i.e. deoxyribose sugars, e.g., at the overhang portions of partially ds RNA); halo (e.g., bromo, chloro, fluoro, or iodo); amino (wherein amino can be, e.g., NH ₂ ; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino,

diheteroarylamino, or amino acid); NH(CH ₂ CH ₂ NH) _n CH ₂ CH ₂ -amino (wherein amino can be, e.g., as described herein), -NHC(0)R (wherein R can be, e.g., alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or sugar), cyano; mercapto; alkyl-thio-alkyl; thioalkoxy; and alkyl, cycloalkyl, aryl, alkenyl and alkynyl, which may be optionally substituted with e.g., an amino as described herein.

The sugar group can also contain one or more carbons that possess the opposite stereochemical configuration than that of the corresponding carbon in ribose. Thus, a modified nucleic acid can include nucleotides containing e.g., arabinose, as the sugar. The nucleotide "monomer" can have an alpha linkage at the 1 ' position on the sugar, e.g., alpha-nucleosides. The modified nucleic acids can also include "abasic" sugars, which lack a nucleobase at C- 1 ' . These abasic sugars can also be further modified at one or more of the constituent sugar atoms. The modified nucleic acids can also include one or more sugars that are in the L form, e.g. L-nucleosides.

Generally, RNA includes the sugar group ribose, which is a 5-membered ring having an oxygen. Exemplary modified nucleosides and modified nucleotides can include, without limitation, replacement of the oxygen in ribose (e.g., with sulfur (S), selenium (Se), or alkylene, such as, e.g., methylene or ethylene); addition of a double bond (e.g., to replace ribose with cyclopentenyl or cyclohexenyl); ring contraction of ribose (e.g., to form a 4-membered ring of cyclobutane or oxetane); ring expansion of ribose (e.g., to form a 6- or 7-membered ring having an additional carbon or heteroatom, such as for example, anhydrohexitol, altritol, mannitol, cyclohexanyl, cyclohexenyl, and morpholino that also has a phosphoramidate backbone). In some embodiments, the modified nucleotides can include multicyclic forms (e.g., tricyclo; and "unlocked" forms, such as glycol nucleic acid (GNA) (e.g., R-GNA or S-GNA, where ribose is replaced by glycol units attached to phosphodiester bonds), threose nucleic acid (TNA, where ribose is replaced with a-L-threofuranosyl-(3'→2')). Modifications on the Nucleobase

The modified nucleosides and modified nucleotides described herein, which can be incorporated into a modified nucleic acid, can include a modified nucleobase. Examples of nucleobases include, but are not limited to, adenine (A), guanine (G), cytosine (C), and uracil (U). These nucleobases can be modified or wholly replaced to provide modified nucleosides and modified nucleotides that can be incorporated into modified nucleic acids. The nucleobase of the nucleotide can be independently selected from a purine, a pyrimidine, a purine or pyrimidine analog. In some embodiments, the nucleobase can include, for example, naturally-occurring and synthetic derivatives of a base.

Exemplary Modified gRNAs

In some embodiments, the modified nucleic acids can be modified gRNAs. It is to be understood that any of the gRNAs described herein can be modified in accordance with this section, including any gRNA that comprises a targeting domain from Tables 1A-I, Tables 2A-I, Tables 3A-H, Tables 4A-I, Tables 5A-I, Tables 6A-I, Tables 7A-H, Tables 8A-H, Tables 9A-I, Tables 10A-I, Tables 11A-I, Tables 12A-I, Tables 13A-K, Tables 14A-K, Tables 15A-F, Tables 16A-K, Tables 17A-K, Tables 18A-K, Tables 19A-J, Tables 20A-J, Tables 21A-K, Tables 22A-K, Tables 23A-J, Tables 24A-K, Tables 25A-G, Tables 26A-G, Table 27, Table 29, Table 31, or Table 32. As discussed herein, transiently expressed or delivered nucleic acids can be prone to degradation by, e.g., cellular nucleases. Accordingly, in one aspect the modified gR As described herein can contain one or more modified nucleosides or nucleotides which introduce stability toward nucleases. While not wishing to be bound by theory it is also believed that certain modified gRNAs described herein can elicit a reduced innate immune response from certain cells, particularly the cells of the present invention (e.g., T-cells). As noted above, the term "innate immune response" includes a cellular response to exogenous nucleic acids, including single stranded nucleic acids, generally of viral or bacterial origin, which involves the induction of cytokine expression and release, particularly the interferons, and cell death.

For example, as discussed herein, we have seen improvements in ex vivo editing of genes in certain cell types (e.g., T cells) when the 5' end of a gRNA is modified by the inclusion of a eukaryotic mRNA cap structure or cap analog. The present invention encompasses the realization that the improvements observed with a 5' capped gRNA can be extended to gRNAs that have been modified in other ways to achieve the same type of structural or functional result (e.g., by the inclusion of modified nucleosides or nucleotides, by the inclusion of a 3' polyA tract and/or when an in vitro transcribed gRNA is modified by treatment with a phosphatase such as calf intestinal alkaline phosphatase to remove the 5' triphosphate group).

Thus, in some embodiments, methods and compositions discussed herein provide methods and compositions where gRNAs have been modified at or near their 5' end (e.g., within 1-10, 1-5, or 1-2 nucleotides of their 5' end). In an embodiment, the 5' end of a gRNA is modified by the inclusion of a eukaryotic mRNA cap structure or cap analog (e.g., a G(5 ')ppp(5 ')G cap analog, a m7G(5 ')ppp(5 ')G cap analog, or a 3 '-0-Me-m7G(5 ')ppp(5 ')G anti reverse cap analog (ARCA)) as depicted in Fig. 19. The cap or cap analog can be included during either chemical synthesis or in vitro transcription of the gRNA. In an embodiment, an in vitro transcribed gRNA is modified by treatment with a phosphatase (e.g., calf intestinal alkaline phosphatase) to remove the 5' triphosphate group.

In some embodiments, a gRNA comprises a modification at or near its 3' end (e.g., within 1-10, 1-5, or 1-2 nucleotides of its 3' end). For example, in some embodiments, the 3' end of a gRNA is modified by the addition of one or more (e.g., 25-200) adenine (A) residues. The polyA tract can be contained in the nucleic acid (e.g., plasmid, PCR product, viral genome) encoding the gRNA, or can be added to the gRNA during chemical synthesis, or following in vitro transcription using a polyadenosine polymerase (e.g., E. coli Poly(A)Polymerase). In some embodiments, gRNAs can be modified at a 3' terminal U ribose. For example, the two terminal hydroxyl groups of the U ribose can be oxidized to aldehyde groups and a concomitant opening of the ribose ring to afford a modified nucleoside as shown below:

wherein "U" can be an unmodified or modified uridine. In another embodiment, the 3 ' terminal U can be modified with a 2' 3' cyclic phosphate as shown below:

wherein "U" can be an unmodified or modified uridine. In some embodiments, the gRNA molecules may contain 3' nucleotides which can be stabilized against degradation, e.g., by incorporating one or more of the modified nucleotides described herein. In this embodiment, e.g., uridines can be replaced with modified uridines, e.g., 5-(2-amino)propyl uridine, and 5-bromo uridine, or with any of the modified uridines described herein; adenosines and guanosines can be replaced with modified adenosines and guanosines, e.g., with modifications at the 8-position, e.g., 8-bromo guanosine, or with any of the modified adenosines or guanosines described herein.

In some embodiments, a gRNA comprises both a modification at or near its 5' end and a modification at or near its 3' end. In an embodiment, in vitro transcribed gRNA contains both a 5' cap structure or cap analog and a 3 ' polyA tract. In an embodiment, an in vitro transcribed gRNA is modified by treatment with a phosphatase (e.g., calf intestinal alkaline phosphatase) to remove the 5' triphosphate group and comprises a 3 ' polyA tract.

While the foregoing has focused on terminal modifications, it is to be understood that methods and compositions discussed herein may use gRNAs that include one or more modified nucleosides or nucleotides at one or more non- terminal positions and/or one or more terminal positions within the gRNA sequence.

In some embodiments, sugar-modified ribonucleotides can be incorporated into the gRNA, e.g., wherein the 2' OH-group is replaced by a group selected from H, -OR, -R (wherein R can be, e.g., alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or sugar), halo, -SH, -SR (wherein R can be, e.g., alkyl, cycloalkyl, aryl, aralkyl, heteroaryl or sugar), amino (wherein amino can be, e.g., NH ₂ ; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, diheteroarylamino, or amino acid); or cyano (- CN). In some embodiments, the phosphate backbone can be modified as described herein, e.g., with a phosphothioate group. In some embodiments, one or more of the nucleotides of the gRNA can each independently be a modified or unmodified nucleotide including, but not limited to 2 '-sugar modified, such as, 2'-0-methyl, 2'-0-methoxyethyl, or 2'-Fluoro modified including, e.g., 2'-F or 2'-0-methyl, adenosine (A), 2'-F or 2'-0-methyl, cytidine (C), 2'-F or 2'-0-methyl, uridine (U), 2'-F or 2'-0-methyl, thymidine (T), 2'-F or 2'-0-methyl, guanosine (G), 2'-0-methoxyethyl-5-methyluridine (Teo), 2'-0- methoxyethyladenosine (Aeo), 2'-0-methoxyethyl-5-methylcytidine (m5Ceo), and any combinations thereof.

In some embodiments, a gRNA can include "locked" nucleic acids (LNA) in which the 2' OH- group can be connected, e.g., by a CI -6 alkylene or CI -6 heteroalkylene bridge, to the 4' carbon of the same ribose sugar, where exemplary bridges can include methylene, propylene, ether, or amino bridges; O-amino (wherein amino can be, e.g., NH ₂ ; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroarylamino, ethylenediamine, or polyamino) and aminoalkoxy or 0(CH ₂ )n-amino (wherein amino can be, e.g., NH ₂ ; alkylamino, dialkylamino, heterocyclyl, arylamino, diarylamino, heteroarylamino, or diheteroarylamino, ethylenediamine, or polyamino).

In some embodiments, a gRNA can include a modified nucleotide which is multicyclic (e.g., tricyclo; and "unlocked" forms, such as glycol nucleic acid (GNA) (e.g., R-GNA or S-GNA, where ribose is replaced by glycol units attached to phosphodiester bonds), or threose nucleic acid (TNA, where ribose is replaced with a-L-threofuranosyl-(3'→2')).

Generally, gRNA molecules include the sugar group ribose, which is a 5-membered ring having an oxygen. Exemplary modified gRNAs can include, without limitation, replacement of the oxygen in ribose (e.g., with sulfur (S), selenium (Se), or alkylene, such as, e.g., methylene or ethylene); addition of a double bond (e.g., to replace ribose with cyclopentenyl or cyclohexenyl); ring contraction of ribose (e.g., to form a 4-membered ring of cyclobutane or oxetane); ring expansion of ribose (e.g., to form a 6- or 7- membered ring having an additional carbon or heteroatom, such as for example, anhydrohexitol, altritol, mannitol, cyclohexanyl, cyclohexenyl, and morpholino that also has a phosphoramidate backbone). Although the majority of sugar analog alterations are localized to the 2' position, other sites are amenable to modification, including the 4' position. In an embodiment, a gRNA comprises a 4'-S, 4'-Se or a 4'-C- aminomethyl-2'-0-Me modification.

In some embodiments, deaza nucleotides, e.g., 7-deaza-adenosine, can be incorporated into the gRNA. In some embodiments, O- and N-alkylated nucleotides, e.g., N6-methyl adenosine, can be incorporated into the gRNA. In some embodiments, one or more or all of the nucleotides in a gRNA molecule are deoxynucleotides. miRNA binding sites microRNAs (or miRNAs) are naturally occurring cellular 19-25 nucleotide long noncoding RNAs. They bind to nucleic acid molecules having an appropriate miRNA binding site, e.g., in the 3' UTR of an mRNA, and down-regulate gene expression. While not wishing to be bound by theory it is believed that the down regulation is either by reducing nucleic acid molecule stability or by inhibiting translation. An RNA species disclosed herein, e.g., an mRNA encoding Cas9 can comprise an miRNA binding site, e.g., in its 3 'UTR. The miRNA binding site can be selected to promote down regulation of expression is a selected cell type. By way of example, the incorporation of a binding site for miR- 122, a microRNA abundant in liver, can inhibit the expression of the gene of interest in the liver. XI. Governing gRNA molecules and the use thereof to limit the activity of a Cas9 system

Methods and compositions that use, or include, a nucleic acid, e.g., DNA, that encodes a Cas9 molecule or a gRNA molecule, can, in addition, use or include a "governing gRNA molecule." The governing gRNA can limit the activity of the other CRISPR/Cas components introduced into a cell or subject. In an embodiment, a gRNA molecule comprises a targeting domain that is complementary to a target domain on a nucleic acid that comprises a sequence that encodes a component of the CRISPR/Cas system that is introduced into a cell or subject. In an embodiment, a governing gRNA molecule comprises a targeting domain that is complementary with a target sequence on: (a) a nucleic acid that encodes a Cas9 molecule; (b) a nucleic acid that encodes a gRNA which comprises a targeting domain that targets the FAS, BID, CTLA4, PDCD1, CBLB, PTPN6, TRAC or TRBC gene (a target gene gRNA); or on more than one nucleic acid that encodes a CRISPR/Cas component, e.g., both (a) and (b). The governing gRNA molecule can complex with the Cas9 molecule to inactivate a component of the system. In an embodiment, a Cas9 molecule/governing gRNA molecule complex inactivates a nucleic acid that comprises the sequence encoding the Cas9 molecule. In an embodiment, a Cas9 molecule/governing gRNA molecule complex inactivates the nucleic acid that comprises the sequence encoding a target gene gRNA molecule. In an embodiment, a Cas9 molecule/governing gRNA molecule complex places temporal, level of expression, or other limits, on activity of the Cas9 molecule/target gene gRNA molecule complex. In an embodiment, a Cas9 molecule/governing gRNA molecule complex reduces off- target or other unwanted activity. In an embodiment, a governing gRNA molecule targets the coding sequence, or a control region, e.g., a promoter, for the CRISPR/Cas system component to be negatively regulated. For example, a governing gRNA can target the coding sequence for a Cas9 molecule, or a control region, e.g., a promoter, that regulates the expression of the Cas9 molecule coding sequence, or a sequence disposed between the two. In an embodiment, a governing gRNA molecule targets the coding sequence, or a control region, e.g., a promoter, for a target gene gRNA. In an embodiment, a governing gRNA, e.g., a Cas9-targeting or target gene gRNA-targeting, governing gRNA molecule, or a nucleic acid that encodes it, is introduced separately, e.g., later, than is the Cas9 molecule or a nucleic acid that encodes it. For example, a first vector, e.g., a viral vector, e.g., an AAV vector, can introduce nucleic acid encoding a Cas9 molecule and one or more target gene gRNA molecules, and a second vector, e.g., a viral vector, e.g., an AAV vector, can introduce nucleic acid encoding a governing gRNA molecule, e.g., a Cas9-targeting or target gene gRNA targeting, gRNA molecule. In an embodiment, the second vector can be introduced after the first. In other embodiments, a governing gRNA molecule, e.g., a Cas9- targeting or target gene gRNA targeting, governing gRNA molecule, or a nucleic acid that encodes it, can be introduced together, e.g., at the same time or in the same vector, with the Cas9 molecule or a nucleic acid that encodes it, but, e.g., under transcriptional control elements, e.g., a promoter or an enhancer, that are activated at a later time, e.g., such that after a period of time the transcription of Cas9 is reduced. In an embodiment, the transcriptional control element is activated intrinsically. In an embodiment, the transcriptional element is activated via the introduction of an external trigger.

Typically a nucleic acid sequence encoding a governing gRNA molecule, e.g., a Cas9-targeting gRNA molecule, is under the control of a different control region, e.g., promoter, than is the component it negatively modulates, e.g., a nucleic acid encoding a Cas9 molecule. In an embodiment, "different control region" refers to simply not being under the contol of one control region, e.g., promoter, that is functionally coupled to both controlled sequences. In an embodiment, different refers to "different control region" in kind or type of control region. For example, the sequence encoding a governing gRNA molecule, e.g., a Cas9-targeting gRNA molecule, is under the control of a control region, e.g., a promoter, that has a lower level of expression, or is expressed later than the sequence which encodes is the component it negatively modulates, e.g., a nucleic acid encoding a Cas9 molecule.

By way of example, a sequence that encodes a governing gRNA molecule, e.g., a Cas9-targeting governing gRNA molecule, can be under the control of a control region (e.g., a promoter) described herein, e.g., human U6 small nuclear promoter, or human HI promoter. In an embodiment, a sequence that encodes the component it negatively regulates, e.g., a nucleic acid encoding a Cas9 molecule, can be under the control of a control region (e.g., a promoter) described herein, e.g., CMV, EF- la, MSCV, PGK, CAG control promoters.

EXAMPLES

The following Examples are merely illustrative and are not intended to limit the scope or content of the invention in any way.

Example 1 : Cloning and Initial Screening of gRNAs The suitability of candidate gR As can be evaluated as described in this example. Although described for a chimeric gRNA, the approach can also be used to evaluate modular gRNAs.

Cloning gRNAs into Vectors

For each gRNA, a pair of overlapping oligonucleotides is designed and obtained.

Oligonucleotides are annealed and ligated into a digested vector backbone containing an upstream U6 promoter and the remaining sequence of a long chimeric gRNA. Plasmid is sequence-verified and prepped to generate sufficient amounts of transfection-quality DNA. Alternate promoters may be used to drive in vivo transcription (e.g., HI promoter) or for in vitro transcription (e.g., a T7 promoter).

Cloning gRNAs in linear dsDNA molecule (STITCHR)

For each gRNA, a single oligonucleotide is designed and obtained. The U6 promoter and the gRNA scaffold (e.g. including everything except the targeting domain, e.g., including sequences derived from the crRNA and tracrRNA, e.g., including a first complementarity domain; a linking domain; a second complementarity domain; a proximal domain; and a tail domain) are separately PCR amplified and purified as dsDNA molecules. The gRNA- specific oligonucleotide is used in a PCR reaction to stitch together the U6 and the gRNA scaffold, linked by the targeting domain specified in the oligonucleotide. Resulting dsDNA molecule (STITCHR product) is purified for transfection. Alternate promoters may be used to drive in vivo transcription (e.g., HI promoter) or for in vitro transcription (e.g., T7 promoter). Any gRNA scaffold may be used to create gRNAs compatible with Cas9s from any bacterial species

Initial gRNA Screen

Each gRNA to be tested is transfected, along with a plasmid expressing Cas9 and a small amount of a GFP-expressing plasmid into human cells. In preliminary experiments, these cells can be immortalized human cell lines such as 293T, K562 or U20S. Alternatively, primary human cells may be used. In this case, cells may be relevant to the eventual therapeutic cell target (for example, an erythroid cell). The use of primary cells similar to the potential therapeutic target cell population may provide important information on gene targeting rates in the context of endogenous chromatin and gene expression.

Transfection may be performed using lipid transfection (such as Lipofectamine or Fugene) or by electroporation (such as Lonza Nucleofection). Following transfection, GFP expression can be determined either by fluorescence microscopy or by flow cytometry to confirm consistent and high levels of transfection. These preliminary transfections can comprise different gRNAs and different targeting approaches (17-mers, 20-mers, nuclease, dual-nickase, etc.) to determine which gRN As/combinations of gRNAs give the greatest activity.

Efficiency of cleavage with each gRNA may be assessed by measuring NHEJ-induced indel formation at the target locus by a T7El-type assay or by sequencing. Alternatively, other mismatch- sensitive enzymes, such as Cell/Surveyor nuclease, may also be used.

For the T7E1 assay, PCR amplicons are approximately 500-700bp with the intended cut site placed asymmetrically in the amplicon. Following amplification, purification and size-verification of PCR products, DNA is denatured and re-hybridized by heating to 95°C and then slowly cooling.

Hybridized PCR products are then digested with T7 Endonuclease I (or other mismatch-sensitive enzyme) which recognizes and cleaves non-perfectly matched DNA. If indels are present in the original template DNA, when the amplicons are denatured and re-annealed, this results in the hybridization of DNA strands harboring different indels and therefore lead to double-stranded DNA that is not perfectly matched.

Digestion products may be visualized by gel electrophoresis or by capillary electrophoresis. The fraction of DNA that is cleaved (density of cleavage products divided by the density of cleaved and unc leaved) may be used to estimate a percent NHEJ using the following equation: %NHEJ = (1-(1 -fraction cleaved) ^½ ). The T7E1 assay is sensitive down to about 2-5% NHEJ.

Sequencing may be used instead of, or in addition to, the T7E1 assay. For Sanger sequencing, purified PCR amplicons are cloned into a plasmid backbone, transformed, miniprepped and sequenced with a single primer. Sanger sequencing may be used for determining the exact nature of indels after determining the NHEJ rate by T7E1.

Sequencing may also be performed using next generation sequencing techniques. When using next generation sequencing, amplicons may be 300-500bp with the intended cut site placed

asymmetrically. Following PCR, next generation sequencing adapters and barcodes (for example Illumina multiplex adapters and indexes) may be added to the ends of the amplicon, e.g., for use in high throughput sequencing (for example on an Illumina MiSeq). This method allows for detection of very low NHEJ rates.

Example 2: Assessment of Gene Targeting by NHEJ

The gRNAs that induce the greatest levels of NHEJ in initial tests can be selected for further evaluation of gene targeting efficiency. In this case, cells are derived from disease subjects and, therefore, harbor the relevant mutation.

Following transfection (usually 2-3 days post-transfection,) genomic DNA may be isolated from a bulk population of transfected cells and PCR may be used to amplify the target region. Following PCR, gene targeting efficiency to generate the desired mutations (either knockout of a target gene or removal of a target sequence motif) may be determined by sequencing. For Sanger sequencing, PCR amplicons may be 500-700bp long. For next generation sequencing, PCR amplicons may be 300-500bp long. If the goal is to knockout gene function, sequencing may be used to assess what percent of alleles have undergone NHEJ-induced indels that result in a frameshift or large deletion or insertion that would be expected to destroy gene function. If the goal is to remove a specific sequence motif, sequencing may be used to assess what percent of alleles have undergone NHEJ-induced deletions that span this sequence.

Example 3: Screening of gRNAs in 293 cells

Screening of gRNAs for T cell receptor beta (TRBC)

In order to identify gRNAs with the highest on target NHEJ efficiency, 42 S. pyogenes and 27 S. aureus gRNAs were selected (Table 27). A DNA template comprised of a U6 promoter, the gRNA target region and appropriate TRACR sequence (S. pyogenes or S. aureus) was generated by a PCR STITCHR reaction. This DNA template was subsequently transfected into 293 cells using Lipofectamine 3000 along with a DNA plasmid encoding the appropriate Cas9 (S. pyogenes or S. aureus) downstream of a CMV promoter. Genomic DNA was isolated from the cells 48-72 hours post transfection. To determine the rate of modification at the T cell receptor beta gene (TRBC), the target region was amplified using a locus PCR with the primers listed in Table 28. After PCR amplification, a T7E1 assay was performed on the PCR product. Briefly, this assay involves melting the PCR product followed by a re-annealing step. If gene modification has occurred, there will exist double stranded products that are not perfect matches due to some frequency of insertions or deletions. These double stranded products are sensitive to cleavage by a T7 endonuclease 1 enzyme at the site of mismatch. It is possible, therefore, to determine the efficiency of cutting by the Cas9/gRNA complex by analyzing the amount of T7E1 cleavage. The formula that is used to provide a measure of % NHEJ from the T7E1 cutting is the following: (100*(l-((l-(fraction cleaved)) ^A 0.5))). The results of this analysis are shown in Fig. 11 and Fig. 12.

In order to identify gRNAs with the highest on target NHEJ efficiency, 18 S. pyogenes and 13 S. gRNAs were selected (Table 29). A DNA template comprised of a U6 promoter, the gRNA target region and appropriate TRACR sequence (S. pyogenes or S. aureus) was generated by a PCR STITCHR reaction. This DNA template was subsequently transfected into 293 cells using Lipofectamine 3000 along with a DNA plasmid encoding the appropriate Cas9 (S. pyogenes or S. aureus) downstream of a CMV promoter. Genomic DNA was isolated from the cells 48-72 hours post transfection. To determine the rate of modification at the T cell receptor alpha gene (TRAC), the target region was amplified using a locus PCR with the primers listed in Table 30. After PCR amplification, a T7E1 assay was performed on the PCR product. Briefly, this assay involves melting the PCR product followed by a re-annealing step. If gene modification has occurred, there will exist double stranded products that are not perfect matches due to some frequency of insertions or deletions. These double stranded products are sensitive to cleavage by a T7 endonuclease 1 enzyme at the site of mismatch.

Screening of gRNAs for PD-1 receptor

In order to identify gRNAs with the highest on target NHEJ efficiency, 48 S. pyogenes and 27 S. aureus gRNAs were selected (see Tables 31 and 32). A DNA template comprised of a U6 promoter, the gRNA target region and appropriate TRACR sequence (S. pyogenes or S. aureus) was generated by a PCR STITCHR reaction. This DNA template was subsequently transfected into 293 cells using

Lipofectamine 3000 along with a DNA plasmid encoding the appropriate Cas9 (S. pyogenes or S. aureus) downstream of a CMV promoter. Genomic DNA was isolated from the cells 48-72 hours post transfection. To determine the rate of modification at the PD-1 gene (PDCD1), the target region was amplified using a locus PCR with the primers listed in Table 33. After PCR amplification, a T7E1 assay was performed on the PCR product. Briefly, this assay involves melting the PCR product followed by a re-annealing step. If gene modification has occurred, there will exist double stranded products that are not perfect matches due to some frequency of insertions or deletions.

Example 4: Enzymatic synthesis and delivery of gRNAs to primary T cells

Delivery of Cas9 mRNA and gRNA as RNA molecules to T cells

To demonstrate Cas9-mediated cutting in primary CD4+ T cells, S. pyogenes Cas9 and a gRNA designed against the TCR beta chain (TRBC-210 (GCGCUGACGAUCUGGGUGAC) (SEQ ID

NO:413)) or the TCR alpha chain (TRAC-4 (GCUGGUACACGGCAGGGUCA) (SEQ ID NO:453)) were delivered as RNA molecules to T cells via electroporation. In this embodiment, both the Cas9 and gRNA were in vitro transcribed using a T7 polymerase. A 5' ARCA cap was added to both RNA species simultaneous to transcription while a polyA tail was added after transcription to the 3 ' end of the RNA species by an E. coli polyA polymerase. To generate CD4+ T cells modified at the TRBC1 and TRBC2 loci, l Oug of Cas9 mRNA and l Oug of TRBC-210 (GCGCUGACGAUCUGGGUGAC) (SEQ ID NO:413) gRNA were introduced to the cells by electroporation. In the same experiment, we also targeted the TRA C gene by introducing 1 Oug of Cas9 mRNA with 1 Oug of TRAC-4

(GCUGGUACACGGCAGGGUCA) (SEQ ID NO:453) gRNA. A gRNA targeting the AAVS 1

(GUCCCCUCCACCCCACAGUG) (SEQ ID NO:51201) genomic site was used as an experimental control. Prior to electroporation, the T cells were cultured in RPMI 1640 supplemented with 10% FBS and recombinant IL-2. The cells were activated using CD3/CD28 beads and expanded for at least 3 days. Subsequent to introduction of the mRNA to the activated T cells, CD3 expression on the cells was monitored at 24, 48 and 72 hours post electroporation by flow cytometry using a fluorescein (APC) conjugated antibody specific for CD3. At 72 hours, a population of CD3 negative cells was observed (Fig. 17A and Fig. 17B). To confirm that the generation of CD3 negative cells was a result of genome editing at the TRBC loci, genomic DNA was harvested and a T7E1 assay was performed. Indeed, the data confirm the presence of DNA modifications at the TRBC2 locus and TRAC locus (Fig. 17C).

Delivery ofCasWgRNA RNP to T cells

To demonstrate Cas9-mediated cutting in Jurkat T cells, S. aureus Cas9 and a gRNA designed against the TCR alpha chain (TRAC-233 (GUGAAUAGGCAGACAGACUUGUCA) (SEQ ID NO:474)) were delivered as a ribonucleic acid protein complex (RNP) by electroporation. In this embodiment, the Cas9 was expressed in E. coli and purified. Specifically, the HJ29 plasmid encoding Cas9 was transformed into Rosetta™ 2 (DE3) chemically competent cells (EMD Millipore #71400-4) and plated onto LB plates with appropriate antibiotics for selection and incubated at 37°C overnight. A lOmL starter culture of Brain Heart Infusion Broth (Teknova #B9993) with appropriate antibiotics was inoculated with 4 colonies and grown at 37°C with shaking at 220rpms. After growing overnight, the starter culture was added to 1L of Terrific Broth Complete (Teknova #T7060) with appropriate antibiotics plus supplements and grown at 37°C with shaking at 220rpms. The temperature was gradually reduced to 18°C and expression of the gene was induced by addition of IPTG to 0.5mM when the OD600 was greater than 2.0. The induction was allowed to continue overnight followed by harvesting the cells by centrifugation and resuspension in TG300 (50mM Tris pH8.0, 300mM NaCl, 20% glycerol, ImM TCEP, protease inhibitor tablets (Thermo Scientific #88266)) and stored at -80°C.

The cells were lysed by thawing the frozen suspension, followed by two passes through a LM10 Microfluidizer® set to 18000psi. The extract was clarified via centrifugation and the soluble extract was captured via batch incubation with Ni-NTA Agarose resin (Qiagen #30230) at 4°C. The slurry was poured into a gravity flow column, washed with TG300+30mM Imidazole and then eluted the protein of interest with TG300+300mM Imidazole. The Ni eluent was diluted with an equal volume of HG100 (50mM Hepes pH7.5, lOOmM NaCl, 10% glycerol, 0.5mM TCEP) and loaded onto a HiTrap SP HP column (GE Healthcare Life Sciences #17- 1152-01) and eluted with a 30 column volume gradient from HG100 to HG1000 (50mM Hepes pH7.5, 1 OOOmM NaCl, 10% glycerol, 0.5mM TCEP). Appropriate fractions were pooled after assaying with an SDS-PAGE gel and concentrated for loading onto a SRT10 SEC300 column (Sepax #225300-21230) equilibrated in HG150 (lOmM Hepes pH7.5, 150mM NaCl, 20% glycerol, ImM TCEP). Fractions were assayed by SDS-PAGE and appropriately pooled, concentrated to at least 5mg/ml.

The gRNA was generated by in vitro transcription using a T7 polymerase. A 5' ARCA cap was added to the RNA simultaneous to transcription while a polyA tail was added after transcription to the 3 ' end of the RNA species by an E. coli polyA polymerase. Prior to introduction into the cells, the purified Cas9 and gRNA were mixed and allowed to form complexes for 10 minutes. The RNP solution was subsequently introduced into Jurkat T cells by electroporation. Prior to and after electroporation, the cells were cultured in RPMI1640 media supplemented with 10% FBS. CD3 expression on the cells was monitored at 24, 48 and 72 hours post electroporation by flow cytometry using a fluorescein conjugated antibody specific for CD3. At 48 and 72 hours, a population of CD3 negative cells was observed (Fig. 18A and Fig. 18B). To confirm that the generation of CD3 negative cells was a result of genome editing at the TRAC locus, genomic DNA was harvested and a T7E1 assay was performed. Indeed, the data confirm the presence of DNA modifications at the TRAC locus (Fig. 18C).

Example 5: Assessing effect of gRNA modifications on T cell viability

In order to assess how gRNA modifications affect T cell viability, S. pyogenes Cas9 mRNA was delivered to Jurkat T cells in combination with an AAVS1 gRNA (GUCCCCUCCACCCCACAGUG) (SEQ ID NO:51201) with or without modification. Specifically, 4 different combinations of modification were analyzed, (1) gRNA with a 5' Anti-Reverse Cap Analog (ARCA) cap (see Fig. 19) and polyA tail, (2) gRNA with a 5' ARCA cap only, (3) gRNA with a polyA tail only, (4) gRNA without any modification. In order to generate all of four of the aforemention versions of modified gRNAs, a DNA template comprising a T7 promoter, AAVS 1 gRNA target sequence (GUCCCCUCCACCCCACAGUG) (SEQ ID NO:51201), and S. pyogenes TRACR sequence. For all gRNAs, T7 polymerase was used to generate the gRNA in the presence of 7.5 mM UTP, 7.5 mM GTP, 7.5 mM CTP and 7.5 mM ATP. In order to modify the gRNAs with a 5' ARCA cap, 6.0 mM of ARCA analog was added to the NTP pool. Consequently, only 1.5 mM of GTP was added while the rest of the NTP pool remained at the same concentration: 7.5 mM UTP, 7.5 mM CTP and 7.5 mM ATP. In order to add a polyA tail to the gRNAs a recombinant polyA polymerase that was purified from E. coli was used to add a series of As to the end of the transcribed gRNA after the in vitro polymerase reaction was terminated. Termination was achieved by eliminating the DNA template with DNase I. The polyA tail reaction was performed for approximately 40 minutes. Regardless of the gRNA modification, all gRNA preparations were purified by

phenokchoroform extraction followed by isopropanol precipitation. Once the gRNAs were generated, Jurkat T cells were electroporated with S. pyogenes Cas9 mRNA (modified with a 5' ARCA cap and polyA tail) and one of the 4 different modified AAVS 1 -specific gRNAs. Following electroporation cell viability was determined by performing an Annexin-V and propidium iodide double stain. The fraction of live cells, which do not stain for Annexin-V and PI was determined by flow cytometry. The results are quantified in Fig. 20. Based on the fraction of live cells, it is concluded that gRNAs that have been modified wuth both a 5' ARCA cap and polyA tail are the least toxic to Jurkat T cells when introduced by electroporation. Example 6: Delivery of Cas9/gRNA RNP to naive T cells

To demonstrate Cas9-mediated cutting in na ^' ive T cells, S. aureus Cas9 and a gRNA designed against the TCR alpha chain with targeting domain GUGAAUAGGCAGACAGACUUGUCA (SEQ ID NO:474) were delivered as a ribonucleic acid protein complex (RNP) by electroporation. In this embodiment, the Cas9 was expressed in E. coli and purified. Specifically, the HJ29 plasmid encoding

Cas9 was transformed into Rosetta™ 2 (DE3) chemically competent cells (EMD Millipore #71400-4) and plated onto LB plates with appropriate antibiotics for selection and incubated at 37°C overnight. A lOmL starter culture of Brain Heart Infusion Broth (Teknova #B9993) with appropriate antibiotics was inoculated with 4 colonies and grown at 37°C with shaking at 220rpms. After growing overnight, the starter culture was added to 1L of Terrific Broth Complete (Teknova #T7060) with appropriate antibiotics plus supplements and grown at 37°C with shaking at 220rpms. The temperature was gradually reduced to 18°C and expression of the gene was induced by addition of IPTG to 0.5mM when the OD600 was greater than 2.0. The induction was allowed to continue overnight followed by harvesting the cells by centrifugation and resuspension in TG300 (50mM Tris pH8.0, 300mM NaCl, 20% glycerol, ImM TCEP, protease inhibitor tablets (Thermo Scientific #88266)) and stored at -80°C.

The cells were lysed by thawing the frozen suspension, followed by two passes through a LM10 Microfluidizer® set to 18000psi. The extract was clarified via centrifugation and the soluble extract was captured via batch incubation with Ni-NTA Agarose resin (Qiagen #30230) at 4°C. The slurry was poured into a gravity flow column, washed with TG300+30mM Imidazole and then eluted the protein of interest with TG300+300mM Imidazole. The Ni eluent was diluted with an equal volume of HG100 (50mM Hepes pH7.5, lOOmM NaCl, 10% glycerol, 0.5mM TCEP) and loaded onto a HiTrap SP HP column (GE Healthcare Life Sciences #17- 1152-01) and eluted with a 30 column volume gradient from HG100 to HG1000 (50mM Hepes pH7.5, lOOOmM NaCl, 10% glycerol, 0.5mM TCEP). Appropriate fractions were pooled after assaying with an SDS-PAGE gel and concentrated for loading onto a SRT10 SEC300 column (Sepax #225300-21230) equilibrated in HG150 (lOmM Hepes pH7.5, 150mM NaCl, 20% glycerol, ImM TCEP). Fractions were assayed by SDS-PAGE and appropriately pooled, concentrated to at least 5mg/ml.

The gRNA with targeting domain GUGAAUAGGCAGACAGACUUGUCA (SEQ ID NO:474) was generated by in vitro transcription using a T7 polymerase. A 5' ARCA cap was added to the RNA simultaneous to transcription while a polyA tail was added after transcription to the 3' end of the RNA species by an E. coli polyA polymerase. In this embodiment, the T cells were isolated from fresh cord blood by a Ficoll gradient followed by positive selection using CD3 magnetic beads. The cells were subsequently cultured in RPMI1640 media supplemented with 10% FBS, IL-7 (5ng/ml) and IL-15 (5ng/ml). 24 hours after isolation, the cells were electroporated with a RNP solution that was generated by incubating the purified Cas9 and gRNA for 10 minutes at room temperature. CD3 expression on the cells was monitored at 96 hours post electroporation by flow cytometry using an APC-conjugated antibody specific for CD3. A population of CD3 negative cells was observed in cells that in which a functional RNP complex was provided versus a negative control that received the gRNA and a non- functional Cas9 (Fig. 21A and Fig. 21B). To confirm that the generation of CD3 negative cells was a result of genome editing at the TRAC locus, genomic DNA was harvested and a T7E1 assay was performed. Indeed, the data confirm the presence of DNA modifications at the TRAC locus (Fig. 21C).
