Impairs hemostasis in the envenomed animal. Inhibits platelet aggregation induced by ADP. Acts by inhibiting fibrinogen interaction with platelet receptors GPIIb/GPIIIa (ITGA2B/ITGB3). Also inhibits platelet aggregate dissociation in human platelet-rich plasma. Binds 1 zinc ion per subunit. Heterodimer with piscivostatin-alpha; 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-IIe sub-subfamily.
