Predicted to enable diacylglycerol cholinephosphotransferase activity and ethanolaminephosphotransferase activity. Predicted to be involved in phosphatidylethanolamine biosynthetic process. Predicted to act upstream of or within phosphatidylcholine biosynthetic process. Predicted to be located in nuclear membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus and endoplasmic reticulum membrane. Orthologous to human CEPT1 (choline/ethanolamine phosphotransferase 1).
