Snake venom zinc metalloproteinase that inhibits ADP-induced platelet aggregation in human platelet-rich plasma (IC(50) is 175 nM) and cleaves alpha-(FGA) and subsequently the beta-chain (FGG) of bovine fibrinogen, leaving the gamma-chain unaffected. It is also able to inhibit proliferatin of ECV304 cells by inducing apoptosis of these cells. Binds 1 zinc ion per subunit. Expressed by the venom gland. The N-terminus is blocked. The disintegrin domain belongs to the long disintegrin subfamily. Belongs to the venom metalloproteinase (M12B) family. P-II subfamily. P-IIb sub-subfamily. This protein does not undergo proteolytic processing to release the disintegrin domain.
