Poor inhibitor of platelet aggregation. The disintegrin inhibits the adhesion of cells expressing the RGD-dependent integrin alpha-5/beta-1 (ITGA5/ITGB1) to immobilized fibronectin. Inhibition on alpha-2b/beta-3 (ITGA2B/ITGB3) is low. Heterodimer with EO5B; disulfide-linked. Expressed by the venom gland. Does not inhibit alpha-1/beta-1 (ITGA1/ITGB1), alpha-2/beta-1 (ITGA2/ITGB1) and alpha-6/beta-1 (ITGA6/ITGB1) integrins. Belongs to the disintegrin family. Dimeric disintegrin subfamily.
