MMP7 (Matrilysin, Matrin, Matrix Metalloproteinase-7, MMP-7, Pump-1 Protease, Uterine Metalloproteinase, MPSL1, PUMP1)

Defensins are a large family of broad-spectrum antimicrobial peptides, identified originally in leukocytes of rabbits and humans. The genes encoding alpha human beta and defensins are clustered in a contiguous segment of chromosome 8p23. Defensins are initially synthesized as inactive prodefensins with a signal peptide that is cleaved off by Matrilysin/MMP7 (a tissue metalloproteinase) to generate mature and bioactive defensin peptide. Matrilysin is expressed in Paneth cell granules together with perhaps more than 20 different -defensins (cryptidins). Disruption of the matrilysin gene prevents the normal posttranslational proteolytic activation of intestinal prodefensins. Matrix metalloproteinase-7 (MMP-7) also known as matrilysin and PUMP (EC 3.4.24.23) cleaves a number of substrates including collagen types IV and X, elastin, fibronectin, gelatin, laminin and proteoglycans. MMP-7 is closely related to the stromelysin family members but is encoded by a different gene. MMP-7 is the smallest of all the MMPs consisting of a pro-peptide domain and a catalytic domain. It lacks the hemopexin-like domain common to other members of the MMPs. MMP-7 is secreted as a 28kD proenzyme and can be activated in vitro by organomercurials and trypsin and in vivo by MMP-3 to a 18kD active MMP-7 enzyme. Once activated, MMP-7 can activate pro-MMP-1 and pro-MMP-9 but not pro-MMP-2. MMP-7 is widely expressed having been reported in elevated levels in cycling endometrium as well as in colorectal cancers and adenomas, hepatocellular carcinomas, rectal carcinomas, and approximately 50% of gliomas.\n\nApplications:\nSuitable for use in ELISA, Western Blot and Immunohistochemistry.
