Description
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}.
