Scorpion venom phospholipase A2 (PLA2) that impacts angiogenesis in vitro and in vivo without showing any cytotoxic or apoptotic signs (PubMed:27940138). The antiangiogenic effect is independent from the catalytic activity and seems to be held by its small subunit (PubMed:27940138). 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. Heterodimer composed of a small subunit and a large subunit; disulfid-linked. Expressed by the venom gland. Belongs to the phospholipase A2 family. Group III subfamily. The large subunit has no homology with other group III PA2 family members, but the small subunit does.
