CC -!- FUNCTION: Has primarily calcium-dependent phospholipase and
CC lysophospholipase activities, with a major role in membrane lipid
CC remodeling and biosynthesis of lipid mediators of the inflammatory
CC response (By similarity). Plays an important role in embryo
CC implantation and parturition through its ability to trigger prostanoid
CC production (By similarity). Preferentially hydrolyzes the ester bond of
CC the fatty acyl group attached at sn-2 position of phospholipids
CC (phospholipase A2 activity). Selectively hydrolyzes sn-2 arachidonoyl
CC group from membrane phospholipids, providing the precursor for
CC eicosanoid biosynthesis via the cyclooxygenase pathway. In an
CC alternative pathway of eicosanoid biosynthesis, hydrolyzes sn-2 fatty
CC acyl chain of eicosanoid lysophopholipids to release free bioactive
CC eicosanoids. Hydrolyzes the ester bond of the fatty acyl group attached
CC at sn-1 position of phospholipids (phospholipase A1 activity) only if
CC an ether linkage rather than an ester linkage is present at the sn-2
CC position. This hydrolysis is not stereospecific. Has calcium-
CC independent phospholipase A2 and lysophospholipase activities in the
CC presence of phosphoinositides. Has O-acyltransferase activity.
CC Catalyzes the transfer of fatty acyl chains from phospholipids to a
CC primary hydroxyl group of glycerol (sn-1 or sn-3), potentially
CC contributing to monoacylglycerol synthesis (By similarity).
