Inhibits the three processes involved in platelet function (adhesion, activation and aggregation). It inhibits platelet adhesion to fibronectin with an IC(50) of 58.6 nM. It inhibits ATP release from platelet induced by ADP with an IC(50) of 19.5 nM on platelet-rich plasma, probably by binding to ADP receptors (P2RY1 and P2RY12). Finally, it inhibits ADP-induced platelet aggregation with IC(50) of 44.7 nM on platelet-rich plasma and 19.3 nM on whole blood, probably by binding to alpha-IIb/beta-3 (ITGA2B/ITGB3) (PubMed:20598348). Inhibits ADP-induced platelet aggregation (IC(50) = 13.8 nM) probably by binding to alpha-IIb/beta-3 (ITGA2B/ITGB3) located on the platelet surface. Monomer (disintegrin). 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.
