At the lipid- aqueous interface, hydrolyzes the ester bond of fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity) (PubMed:10066756, PubMed:18434304). Specifically targets phospholipids with a short-chain fatty acyl group at sn-2 position. Can hydrolyze phospholipids with long fatty acyl chains, only if they carry oxidized functional groups. Hydrolyzes and inactivates platelet- activating factor (PAF, 1-O-alkyl-2-acetyl-sn-glycero-3- phosphocholine), a potent proinflammatory signaling lipid that acts through PTAFR on various innate immune cells (PubMed:10066756, PubMed:18434304). Hydrolyzes oxidatively truncated phospholipids carrying an aldehyde group at omega position, preventing their accumulation in lipoprotein particles and uncontrolled proinflammatory effects. As part of high-density lipoprotein (HDL) particles, can hydrolyze phospholipids having long-chain fatty acyl hydroperoxides at sn-2 position and protect against potential accumulation of these oxylipins in the vascular wall. Catalyzes the release from membrane phospholipids of F2-isoprostanes, lipid biomarkers of cellular oxidative damage. [The UniProt Consortium]
