Enables 1-acylglycerol-3-phosphate O-acyltransferase activity and 1-acylglycerophosphocholine O-acyltransferase activity. Predicted to be involved in phosphatidylcholine acyl-chain remodeling and phospholipid biosynthetic process. Predicted to act upstream of or within several processes, including negative regulation of phosphatidylcholine biosynthetic process; positive regulation of protein catabolic process; and surfactant homeostasis. Predicted to be located in several cellular components, including Golgi apparatus; endoplasmic reticulum; and lipid droplet. Orthologous to human LPCAT1 (lysophosphatidylcholine acyltransferase 1).
