platelet-activating factor acetylhydrolase II, HSD-PLA2
This gene encodes platelet-activating factor acetylhydrolase isoform 2, a single-subunit intracellular enzyme that catalyzes the removal of the acetyl group at the SN-2 position of platelet-activating factor (identified as 1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine). However, this lipase exhibits a broader substrate specificity than simply platelet activating factor. Two other isoforms of intracellular platelet-activating factor acetylhydrolase exist, and both are multi-subunit enzymes. Additionally, there is a single-subunit serum isoform of this enzyme.

PAF-AH II exerts strong neuroprotective effects against ischemic injury: the neurological deficit scores, cerebral edema index, and relative infarction volume are all significantly lower in PAFAH2 transgenic mice than in wild-type mice.

Using expressed sequence tag (EST) homology screening, a new human serine dependent phospholipase A2 (HSD-PLA2) was identified that has 40% amino acid identity with human low density lipoprotein-associated phospholipase A2 (LDL-PLA2).
