Inhibits fibrinogen interaction with platelets. Acts by binding to alpha-IIb/beta-3 (ITGA2B/ITGB3) on the platelet surface and inhibits aggregation induced by ADP, thrombin, platelet-activating factor and collagen (By similarity). Inhibits cell adhesion to vitronectin, probably by blocking its receptor integrin alpha-V/beta-3 (ITGAV/ITGB3), and to fibronectin in vitro (PubMed:26163300, PubMed:27060015). Shows little to no cytotoxicity in vitro (PubMed:26163300, PubMed:27060015). Expressed by the venom gland. The disintegrin belongs to the medium disintegrin subfamily. Belongs to the venom metalloproteinase (M12B) family. P-II subfamily. P-IIa sub-subfamily.
