Title:
HIGHLY EFFICIENT AND CONTROLLABLE EXPRESSION SYSTEM FOR ENDOGENOUS PIGGYBACKING EXOGENEOUS GENES
Document Type and Number:
WIPO Patent Application WO/2021/088370
Kind Code:
A1
Abstract:
Provided is a fungal operon, an exogeneous gene site-directed quantitative fixed-time expression system based on the fungal operon, and applications of the system in expressing heterogeneous genes. The system comprises the following sequences connected in series: a host target gene stop codon upstream fragment containing a stop codon, a fungal operon intergenic region, a target gene, and a DNA fragment of a host target gene stop codon downstream fragment. The system utilizes the fungal operon intergenic region to serially connect the target gene, inserts same to the downstream of a host cell expression gene stop codon by means of site-directed gene insertion, and utilizes a promoter of the target gene to complete the transcriptional expression of the target gene.
