Impairs hemostasis in the envenomed animal. Disintegrin: Inhibits ADP- (IC(50)=59 nM) and collagen-induced (IC(50)=49 nM) aggregation of human platelets. In vitro, inhibits adhesion of endothelial cells to vitronectin, type-I collagen and, to a lower degree, fibronectin and laminin. Binds 1 zinc ion per subunit. Monomer. Expressed by the venom gland. Disintegrin bothrasperin. The disintegrin belongs to the medium disintegrin subfamily. Belongs to the venom metalloproteinase (M12B) family. P-II subfamily. P-IId sub-subfamily.
