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. Homodimer; disulfide-linked. Expressed by the venom gland. Homodimer. Does no inhibit alpha-1/beta-1 (ITGA1/ITGB1), alpha-2/beta-1 (ITGA2/ITGB1) and alpha-6/beta-1 (ITGA6/ITGB1). Belongs to the disintegrin family. Dimeric disintegrin subfamily.
