Anti-MMP-7, clone ID-2

Matrix metalloproteinases (MMPs) are a family of enzymes that are responsible for the degradation of extracellular matrix components such as collagen, laminin and proteoglycans. In addition to sequence homology, all MMPs share the following characteristics: the catalytic mechanism is dependent upon a zinc ion at the active center, they cleave one or more extracellular matrix components, they are secreted as zymogens which are activated by removal of an approximately 10 kDa segment from the N-terminus and they are inhibited by tissue inhibitor of metalloproteinases (TIMP). These enzymes are involved in normal physiological processes such as embryogenesis and tissue remodeling and may play an important role in angiogenesis, arthritis, periodontitis, and metastasis. 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 28 kDa proenzyme and can be activated in vitro by organomercurials (e.g., 4-aminophenylmercuric acetate, APMA) and trypsin and in vivo by MMP-3 to a 18 kDa 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, pancreatic carcinomas and approximately 50% of gliomas.

Matrilysin; PUMP-1

ID-2

Antibody recognizes proteins of ~28 kDa and ~18 kDa which are identified as pro (latent) and active forms of matrix metalloproteinase-7. The antibody shows no cross-reaction with the pro and active forms of other MMPs.

Cellular Localization: Cytoplasmic (Visscher et al., 1994).
