Snake venom phospholipase A2 (PLA2) that displays an inhibitory effect, independent from its catalytic activity, on tumor cell adhesion and migration. This effect is mediated via specific inhibition of integrins alpha-5/beta-1 (ITGA5/ITGB1), alpha-v/beta-3 (ITGAV/ITGB3) and alpha-v/beta-6 (ITGAV/ITGB6). 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. Concentrations up to 2 uM during 4 days does not induce detectable cytotoxicity on human melanoma and fibrosarcoma cell lines. Belongs to the phospholipase A2 family. Group II subfamily. D49 sub-subfamily.
