Snake venom phospholipase A2 that inhibits blood coagulation and platelet aggregation induced by ADP and arachidonic acid. Inhibits tumor cell adhesion and migration in a dose-dependent manner. Abolishes the attachment of human brain microvascular endothelial cells (HBMEC) to fibrinogen (IC(50)=0.2 uM) and dramatically reduces it adhesion to fibronectin (IC(50)=0.3 uM), whereas no effect is observed on type I collagen, vitronectin or laminin 1. Also blocks the cell migration toward fibronectin and fibrinogen. These effects are not dependent of the catalytic activity, but are mediated by alpha-5/beta-1 (ITGA5/ITGB1) and alpha-v-containing (ITGAV) integrins. Also shows anti-angiogenic activity in chicken chorioallantoix membrane assay. Has a relatively high enzymatic activity. PLA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. a 1,2-diacyl-sn-glycero-3-phosphocholine + H2O = a 1-acyl-sn-glycero-3-phosphocholine + a fatty acid + H(+) Binds 1 Ca(2+) ion. Expressed by the venom gland. Glycosylated (2.5%). Does not show cytotoxic activity on human fibrosarcoma and melanoma cell lines. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily.
