CC -!- FUNCTION: Ubiquitinous metalloproteinase that is involved in diverse
CC functions such as remodeling of the vasculature, angiogenesis, tissue
CC repair, tumor invasion, inflammation, and atherosclerotic plaque
CC rupture. As well as degrading extracellular matrix proteins, can also
CC act on several nonmatrix proteins such as big endothelial 1 and beta-
CC type CGRP promoting vasoconstriction. Also cleaves KISS at a Gly-|-Leu
CC bond. Appears to have a role in myocardial cell death pathways.
CC Contributes to myocardial oxidative stress by regulating the activity
CC of GSK3beta. Cleaves GSK3beta in vitro. Involved in the formation of
CC the fibrovascular tissues. {ECO:0000256|ARBA:ARBA00059630}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Cleavage of gelatin type I and collagen types IV, V, VII, X.
CC Cleaves the collagen-like sequence Pro-Gln-Gly-|-Ile-Ala-Gly-Gln.;
CC EC=3.4.24.24; Evidence={ECO:0000256|ARBA:ARBA00000178};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000256|PIRSR:PIRSR621190-2};
CC Note=Can bind about 5 Ca(2+) ions per subunit.
CC {ECO:0000256|PIRSR:PIRSR621190-2};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000256|PIRSR:PIRSR621190-2};
CC Note=Binds 2 Zn(2+) ions per subunit. {ECO:0000256|PIRSR:PIRSR621190-
CC 2};
CC -!- SUBUNIT: Interacts (via the C-terminal hemopexin-like domains-
CC containing region) with the integrin alpha-V/beta-3; the interaction
CC promotes vascular invasion in angiogenic vessels and melamoma cells.
CC Interacts (via the C-terminal PEX domain) with TIMP2 (via the C-
CC terminal); the interaction inhibits the degradation activity. Interacts
CC with GSK3B. {ECO:0000256|ARBA:ARBA00026006}.
CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC matrix {ECO:0000256|ARBA:ARBA00004498}.
CC -!- SIMILARITY: Belongs to the peptidase M10A family.
CC {ECO:0000256|ARBA:ARBA00010370}.
