Secretory calcium-dependent phospholipase A2 that primarily targets extracellular phospholipids. Hydrolyzes the ester bond of the fatty acyl group attached at the sn-2 position of phospholipids (phospholipase A2 activity), the catalytic efficiency decreasing in the following order: phosphatidylglycerols > phosphatidylethanolamines > phosphatidylcholines > phosphatidylserines (PubMed: 11112443). May play a role in lipid mediator production in inflammatory conditions, by providing arachidonic acid to downstream cyclooxygenases and lipoxygenases (By similarity).
