Comment typeDescription
Alternative Products Event=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q96PD7-1; Sequence=Displayed; Name=2; IsoId=Q96PD7-2; Sequence=VSP_020356;
Catalytic Activity Acyl-CoA + 1,2-diacylglycerol = CoA + triacylglycerol. {ECO:0000269|PubMed:16214399}.
Catalytic Activity Acyl-CoA + retinol = CoA + retinyl ester. {ECO:0000269|PubMed:16214399}.
Enzyme Regulation Inhibited by niacin. {ECO:0000250}.
Function Essential acyltransferase that catalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. Required for synthesis and storage of intracellular triglycerides. Probably plays a central role in cytosolic lipid accumulation. In liver, is primarily responsible for incorporating endogenously synthesized fatty acids into triglycerides (By similarity). Functions also as an acyl-CoA retinol acyltransferase (ARAT). {ECO:0000250}.
Pathway Glycerolipid metabolism; triacylglycerol biosynthesis.
Sequence Caution Sequence=BAD38635.1; Type=Erroneous initiation; Evidence={ECO:0000305}; Sequence=CAD38961.1; Type=Erroneous initiation; Evidence={ECO:0000305};
Similarity Belongs to the diacylglycerol acyltransferase family. {ECO:0000305}.
Subcellular Location Endoplasmic reticulum membrane {ECO:0000269|PubMed:14521909}; Multi-pass membrane protein {ECO:0000269|PubMed:14521909}. Lipid droplet {ECO:0000250}.
Subunit Forms multimeric complexes consisting of several DGAT2 subunits. {ECO:0000250}.
Tissue Specificity Predominantly expressed in liver and white adipose tissue. Expressed at lower level in mammary gland, testis and peripheral blood leukocytes. Expressed in sebaceous glands of normal skin but decreased psoriatic skin. {ECO:0000269|PubMed:11481335, ECO:0000269|PubMed:14521909}.
