CC   -!- FUNCTION: Inhibits fibrinogen interaction with platelets. Acts by
CC       binding to alpha-IIb/beta-3 (ITGA2B/ITGB3) on the platelet surface and
CC       inhibits aggregation induced by ADP, thrombin, platelet-activating
CC       factor and collagen (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Monomer (disintegrin). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- MISCELLANEOUS: The disintegrin belongs to the medium disintegrin
CC       subfamily.
CC   -!- SIMILARITY: Belongs to the venom metalloproteinase (M12B) family. P-II
CC       subfamily. P-IIa sub-subfamily. {ECO:0000305}.
