General annotation (Comments)

Function	Catalyzes the formation of diacylglycerol from 2-monoacylglycerol and fatty acyl-CoA. Also able to catalyze the terminal step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. Has a preference toward palmitoyl-CoA and oleoyl-CoA. May be involved in absorption of dietary fat in the small intestine by catalyzing the resynthesis of triacylglycerol in enterocytes. Ref.1
Catalytic activity	Acyl-CoA + 2-acylglycerol = CoA + diacylglycerol. Ref.1 Acyl-CoA + 1,2-diacylglycerol = CoA + triacylglycerol. Ref.1
Pathway	Glycerolipid metabolism; triacylglycerol biosynthesis.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein By similarity Ref.1.
Tissue specificity	Selectively expressed in the digestive system. Highly expressed in the ileum, and at lower level in jejunum, duodenum, colon, cecum and the rectum. Not expressed in the stomach and the esophagus and trachea. Expressed at very low level in liver. Ref.1
Sequence similarities	Belongs to the diacylglycerol acyltransferase family.
Biophysicochemical properties	Kinetic parameters: Vmax=9.3 nmol/min/mg enzyme with diacylglycerol as substrate Vmax=22.8 nmol/min/mg enzyme with 2-monoacylglycerol as substrate
Sequence caution	The sequence AAD45832.1 differs from that shown. Reason: Erroneous gene model prediction.
