Enables lysophospholipase activity. Involved in N-acylphosphatidylethanolamine metabolic process. Acts upstream of or within N-acylethanolamine metabolic process. Predicted to be active in lipid droplet and mitochondrion. Is expressed in central nervous system; dorsal root ganglion; genitourinary system; and retina. Orthologous to human ABHD4 (abhydrolase domain containing 4, N-acyl phospholipase B). [provided by Alliance of Genome Resources, Apr 2022]
