Mouse Cytosolic Phospholipase A2, CPLA2 ELI

Has primarily calcium-dependent phospholipase and lysophospholipase activities, with a major role in membrane lipid remodeling and biosynthesis of lipid mediators of the inflammatory response (PubMed: 1904318, PubMed: 9403692, PubMed: 9403693).

Plays an important role in embryo implantation and parturition through its ability to trigger prostanoid production (PubMed: 9403692, PubMed: 9403693).

Preferentially hydrolyzes the ester bond of the fatty acyl group attached at sn-2 position of phospholipids (phospholipase A2 activity).

Selectively hydrolyzes sn-2 arachidonoyl group from membrane phospholipids, providing the precursor for eicosanoid biosynthesis via the cyclooxygenase pathway.

In an alternative pathway of eicosanoid biosynthesis, hydrolyzes sn-2 fatty acyl chain of eicosanoid lysophopholipids to release free bioactive eicosanoids.

Hydrolyzes the ester bond of the fatty acyl group attached at sn-1 position of phospholipids (phospholipase A1 activity) only if an ether linkage rather than an ester linkage is present at the sn-2 position.

This hydrolysis is not stereospecific.

Has calcium-independent phospholipase A2 and lysophospholipase activities in the presence of phosphoinositides.

Has O-acyltransferase activity.

Catalyzes the transfer of fatty acyl chains from phospholipids to a primary hydroxyl group of glycerol (sn-1 or sn-3), potentially contributing to monoacylglycerol synthesis (By similarity).
