Snake venom zinc metalloproteinase-disintegrin-like that blocks the interaction between platelets and collagen fibers through its binding to collagen fibers, resulting in the blockade of collagen-mediated platelet functions such as adhesion, release reaction, thromboxane formation, and aggregation. Binds selectively to collagen type I with high affinity. Also exerts proteolytic activity to matrix. Binds 1 zinc ion per subunit. Monomer. Expressed by the venom gland. Belongs to the venom metalloproteinase (M12B) family. P-III subfamily. P-IIIa sub-subfamily.
