General annotation (Comments)

Function

Ubiquitinous metalloproteinase that is involved in diverse functions such as remodeling of the vasculature, angiogenesis, tissue repair, tumor invasion, inflammation, and atherosclerotic plaque rupture. As well as degrading extracellular matrix proteins, can also act on several nonmatrix proteins such as big endothelial 1 and beta-type CGRP promoting vasoconstriction. Also cleaves KISS at a Gly-|-Leu bond. Appears to have a role in myocardial cell death pathways. Contributes to myocardial oxidative stress by regulating the activity of GSK3beta. Cleaves GSK3beta in vitro By similarity. Ref.4

PEX, the C-terminal non-catalytic fragment of MMP2, posseses anti-angiogenic and anti-tumor properties and inhibits cell migration and cell adhesion to FGF2 and vitronectin. Ligand for integrin alpha-v/beta-3 on the surface of blood vessels By similarity. Ref.4

Isoform 2: Mediates the proteolysis of CHUK/IKKA and initiates a primary innate immune response by inducing mitochondrial-nuclear stress signaling with activation of the pro-inflammatory NF-kappaB, NFAT and IRF transcriptional pathways. Ref.4

Catalytic activity

Cleavage of gelatin type I and collagen types IV, V, VII, X. Cleaves the collagen-like sequence Pro-Gln-Gly-|-Ile-Ala-Gly-Gln.

Cofactor

Binds 4 calcium ions per subunit By similarity.

Binds 2 zinc ions per subunit By similarity.

Subunit structure

Interacts (via the C-terminal hemopexin-like domains-containing region) with the integrin alpha-V/beta-3; the interaction promotes vascular invasion in angiogenic vessels and melamoma cells. Interacts (via the C-terminal PEX domain) with TIMP2 (via the C-terminal); the interaction inhibits the degradation activity. Interacts with GSK3B By similarity.

Subcellular location

Isoform 1: Secreted › extracellular space › extracellular matrix By similarity. Membrane By similarity. Nucleus By similarity. Note: Colocalizes with integrin alphaV/beta3 at the membrane surface in angiogenic blood vessels and melanomas. Found in mitochondria, along microfibrils, and in nuclei of cardiomyocytes By similarity. Ref.4

Isoform 2: Cytoplasm. Mitochondrion Ref.4.

Developmental stage

Present in unfertilized eggs and at the zygote and cleavage stages. Levels increase at the blastocyst stage and with endoderm differentiation. Ref.3

Domain

The conserved cysteine present in the cysteine-switch motif binds the catalytic zinc ion, thus inhibiting the enzyme. The dissociation of the cysteine from the zinc ion upon the activation-peptide release activates the enzyme.

Post-translational modification

Phosphorylation on multiple sites modulates enzymatic activity. Phosphorylated by PKC in vitro By similarity.

The propeptide is processed by MMP14 (MT-MMP1) and MMP16 (MT-MMP3) By similarity. Autocatalytic cleavage in the C-terminal produces the anti-angiogenic peptide, PEX. This processing appears to be facilitated by binding integrinv/beta3 By similarity.

Sequence similarities

Belongs to the peptidase M10A family.

Contains 3 fibronectin type-II domains.

Contains 4 hemopexin-like domains.
