Document Type and Number:
WIPO Patent Application WO/1992/015615
Kind Code:
A1
Abstract:
A novel serum calcium depressing factor derived from swine pancreas, which has a molecular weight of 26,500 to 28,000 D as determined by polyacrylamide gel electrophoresis, an isoelectric point of about 4.5 as determined by isoelectric electrophoresis, and an amino acid sequence of Val-Val-Gly-Gly-Gln-Asn-Ala-Ile-Pro-His-Ser-Trp-Pro-Trp-Gln-Ile-Arg-Leu- at or near the N-terminus. It has a protease activity and is inhibited by PMSF, chymostatin and trypsin inhibitor but not by APMSF and E-64. The novel depressing factor is expected to be applicable as a medicine for treating and preventing bone diseases such as osteoporosis.
