Protein attributes

Sequence length	617 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates By similarity.
Catalytic activity	Acyl-CoA + 1,2-diacylglycerol = CoA + triacylglycerol.
Pathway	Lipid metabolism; glycerolipid metabolism.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity.
Sequence similarities	Belongs to the membrane-bound acyltransferase family. Sterol o-acyltransferase subfamily.
Sequence caution	The sequence EAL71801.1 differs from that shown. Reason: Erroneous gene model prediction.
