2-MAG and DAG are transacylated to TAG by PNPLA2/3 At the endoplasmic reticulum (ER) membrane, a 2-monoacylglycerol (2-MAG) molecule and a diacylglycerol (DAG) molecule are transacylated by patatin-like phospholipase domain-containing proteins 2/3 (PNPLA2/3). This forms triacylglycerol (TAG) and glycerol (Jenkins et al. 2004).
