CC   -!- FUNCTION: Inhibits ADP- (IC(50)=56 nM) and collagen-induced (IC(50)=49
CC       nM) aggregation of human platelets. In vitro, inhibits adhesion of
CC       endothelial cells to vitronectin, type-I collagen and, to a lower
CC       degree, fibronectin and laminin. {ECO:0000269|PubMed:25457103}.
CC   -!- SUBUNIT: Monomer. {ECO:0000250|UniProtKB:P17497}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:25457103}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000305|PubMed:25457103}.
CC   -!- MASS SPECTROMETRY: Mass=7106; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:25457103};
CC   -!- MISCELLANEOUS: The disintegrin belongs to the medium disintegrin
CC       subfamily. {ECO:0000305|PubMed:25457103}.
CC   -!- SIMILARITY: Belongs to the venom metalloproteinase (M12B) family. P-II
CC       subfamily. P-IIa sub-subfamily. {ECO:0000305}.
