CC -!- FUNCTION: Hydrolyzes the ester bond of the acyl group attached at the
CC sn-1 position of phosphatidylserines (phospholipase A1 activity) and 1-
CC acyl-2-lysophosphatidylserines (lysophospholipase activity) in the
CC pathway of phosphatidylserines acyl chain remodeling (By similarity).
CC Cleaves phosphatidylserines exposed on the outer leaflet of the plasma
CC membrane of apoptotic cells producing 2-acyl-1-lysophosphatidylserines,
CC which in turn enhance mast cell activation and histamine production.
CC Has no activity toward other glycerophospholipids including
CC phosphatidylcholines, phosphatidylethanolamines, phosphatidic acids or
CC phosphatidylinositols, or glycerolipids such as triolein (By
CC similarity). {ECO:0000250|UniProtKB:P97535,
