Enables 2-acylglycerol O-acyltransferase activity and acetyltransferase activity. Acts upstream of or within diacylglycerol biosynthetic process; intestinal absorption; and triglyceride biosynthetic process. Predicted to be located in perinuclear endoplasmic reticulum membrane. Is expressed in several structures, including embryo endoderm; liver; metanephros; somite; and yolk sac endoderm. Orthologous to human MOGAT2 (monoacylglycerol O-acyltransferase 2).
