General annotation (Comments)

Function	Catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. Required for storage lipid synthesis. May be involved in lipid particle synthesis from the endoplasmic reticulum and ergosterol biosynthesis. Ref.2 Ref.3 Ref.4 Ref.7 Ref.8
Catalytic activity	Acyl-CoA + 1,2-diacylglycerol = CoA + triacylglycerol.
Pathway	Glycerolipid metabolism; triacylglycerol biosynthesis.
Subcellular location	Endoplasmic reticulum membrane; Single-pass membrane protein Potential. Lipid droplet Ref.2 Ref.5.
Miscellaneous	Present with 907 molecules/cell in log phase SD medium. Ref.6
Sequence similarities	Belongs to the diacylglycerol acyltransferase family.
