Enables acylglycerol O-acyltransferase activity; calcium-independent phospholipase A2 activity; and phospholipase A1 activity. Involved in diacylglycerol biosynthetic process; phosphatidylcholine catabolic process; and phosphatidylethanolamine catabolic process. Acts upstream of or within ceramide metabolic process. Located in extracellular space and lysosome. Is expressed in several structures, including adrenal gland; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human PLA2G15 (phospholipase A2 group XV). [provided by Alliance of Genome Resources, Apr 2022]
