Enables O-acyltransferase activity and lysophospholipid acyltransferase activity. Involved in phosphatidylinositol acyl-chain remodeling and regulation of triglyceride metabolic process. Acts upstream of or within layer formation in cerebral cortex; phosphatidylinositol metabolic process; and ventricular system development. Located in membrane. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and respiratory system. Used to study hydrocephalus. Human ortholog(s) of this gene implicated in autosomal recessive non-syndromic intellectual disability. Orthologous to human MBOAT7 (membrane bound O-acyltransferase domain containing 7).
