MetaCyc Polypeptide: procollagenase

Gene: MMP2 Accession Number: HS01565 (MetaCyc)

Synonyms: CLG4A, 72 kDa gelatinase, gelatinase A, matrix metalloproteinase-2, MMP-2, TBE-1

Species: Homo sapiens

Alternative forms of procollagenase: type IV collagenase (extended summary available)

Summary:
Proteins of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, and tissue remodeling, as well as in disease processes, such as arthritis and metastasis. Most MMP's are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases.

MMP2 is a ubiquitinous metalloproteinase that is involved in diverse functions such as remodeling of the vasculature, angiogenesis, tissue repair, tumor invasion, inflammation, and atherosclerotic plaque rupture. It degrades gelatin type I and collagen types IV, V, VII, and X. It cleaves the collagen-like sequence Pro-Gln-Gly-|-Ile-Ala-Gly-Gln.

The propeptide is processed by MMP14 (MT-MMP1) and MMP16 (MT-MMP3). The active protein binds 4 calcium ions and 2 zinc ions per subunit. In addition, autocatalytic cleavage in the C-terminal produces the anti-angiogenic peptide PEX. This processing appears to be facilitated by binding integrinv/beta3.
