CC -!- FUNCTION: Snake venom zinc metalloproteinase that inhibits ADP-induced CC human platelet aggregation (IC(50)=120 nM (native) and IC(50)=248 nM CC (recombinant)). May act by binding to the receptor GPIIb/GPIIIa CC (ITGA2B/ITGB3) on the platelet surface (PubMed:14511668). Degrades the CC alpha-chain of fibrinogen completely and the beta-chain partially, CC leaving the gamma chain intact (Ref.2). Also inhibits the growth of CC several cell lines, including human liver cancer cells (Bel7402), human CC leukemia cells (K562) and human gastric carcinoma cells (BGC823) CC (PubMed:19732785). {ECO:0000269|PubMed:14511668, CC ECO:0000269|PubMed:19732785, ECO:0000269|Ref.2}. CC -!- COFACTOR: CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250}; CC Note=Binds 1 zinc ion per subunit. {ECO:0000250}; CC -!- ACTIVITY REGULATION: Fibrinogenolytic activity is completely inhibited CC by EDTA, but not by PMSF. {ECO:0000269|Ref.2}. CC -!- SUBUNIT: Monomer. {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:14511668}. CC -!- TISSUE SPECIFICITY: Expressed by the venom gland. CC {ECO:0000305|PubMed:14511668}. CC -!- PTM: The N-terminus is blocked. {ECO:0000269|PubMed:14511668}. CC -!- MISCELLANEOUS: Negative results: does not show hemorrhagic activities CC after intradermal injection in mice. Does not show pro-coagulant and CC anti-coagulant activities (Ref.2). CC -!- MISCELLANEOUS: The disintegrin domain belongs to the long disintegrin CC subfamily. {ECO:0000305}. CC -!- SIMILARITY: Belongs to the venom metalloproteinase (M12B) family. P-II CC subfamily. P-IIb sub-subfamily. {ECO:0000305}.
