Plasma membrane phospholipids are hydrolyzed to arachidonic acid and lysophospholipid through the action of phospholipase A2 (PLA2). The PLA2 enzymes are classified into the calcium-dependent secreted sPLA2 and cytosolic cPLA2 and the calcium independent iPLA2 categories and further divided into several groups and subgroups. PLA2s catalyze the release of fatty acids from the sn-2 position of phospholipids. Of the cPLA2s, the group IV-A member known as Pla2g4a, preferentially hydrolyzes membrane
