Predicted to enable glycerol-3-phosphate O-acyltransferase activity. Predicted to be involved in acyl-CoA metabolic process; phosphatidylcholine biosynthetic process; and triglyceride biosynthetic process. Predicted to act upstream of or within several processes, including acylglycerol metabolic process; glandular epithelial cell maturation; and lactation. Predicted to be located in endoplasmic reticulum and membrane. Orthologous to human GPAT4 (glycerol-3-phosphate acyltransferase 4). [provided by Alliance of Genome Resources, Apr 2022]
