CC -!- FUNCTION: Essential acyltransferase that catalyzes the terminal and
CC only committed step in triacylglycerol synthesis by using
CC diacylglycerol and fatty acyl CoA as substrates. Required for synthesis
CC and storage of intracellular triglycerides. Probably plays a central
CC role in cytosolic lipid accumulation (By similarity).
