Enables 1-acylglycerophosphocholine O-acyltransferase activity. Involved in phosphatidylcholine acyl-chain remodeling. Predicted to be located in endoplasmic reticulum. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human LPCAT4 (lysophosphatidylcholine acyltransferase 4). [provided by Alliance of Genome Resources, Apr 2022]
