group 10 secretory phospholipase A2,group X secretory phospholipase A2,GXPLA2,GXSPLA2,phosphatidylcholine 2-acylhydrolase 10,SPLA2,sPLA2-X.
PA2 catalyzes the calcium-dependent hydrolysis of the 2-acyl groups in 3-sn-phosphoglycerides. Has a powerful potency for releasing arachidonic acid from cell membrane phospholipids. Prefers phosphatidylethanolamine and phosphatidylcholine liposomes to those of phosphatidylserine.
