This recombinant protein hydrolyzes fibronectin, but has no effect on type I gelatin and type I to V collagens. Selectively hydrolyzes the Aalpha-chain of fibrinogen (FGA), but has no effect on fibrin. Inhibits ADP-induced platelet aggregation. Recombinant metalloproteinase-disintegrin Mt-d-I (393-408): hydrolyzes type I gelatin, type III and V collagens, but has no effect on type I, II, IV collagens and fibronectin. Selectively hydrolyzes the Aalpha-chain of fibrinogen, but has no effect on fibrin. May induce hemorrhage in vascular tissue. Strongly inhibits ADP-induced platelet aggregation. When concentrated, Mt-d-I undergoes autoproteolytic processing into metalloproteinase and disintegrin. Binds 1 zinc ion per subunit. Homodimer; disulfide-linked (disintegrin). Expressed by the venom gland. The disintegrin belongs to the dimeric disintegrin subfamily. Belongs to the venom metalloproteinase (M12B) family. P-II subfamily. P-IId sub-subfamily.
