This gene encodes one of two enzymes which catalyzes the final reaction in the synthesis of triglycerides in which diacylglycerol is covalently bound to long chain fatty acyl-CoAs. The encoded protein catalyzes this reaction at low concentrations of magnesium chloride while the other enzyme has high activity at high concentrations of magnesium chloride. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]
GeneCards Summary for DGAT2 Gene
DGAT2 (Diacylglycerol O-Acyltransferase 2) is a Protein Coding gene. Diseases associated with DGAT2 include Autosomal Dominant Charcot-Marie-Tooth Disease Type 2 Due To Dgat2 Mutation and Mental Retardation, Autosomal Dominant 38. Among its related pathways are Glycerophospholipid biosynthesis and triacylglycerol biosynthesis. Gene Ontology (GO) annotations related to this gene include protein homodimerization activity and 2-acylglycerol O-acyltransferase activity. An important paralog of this gene is DGAT2L6.
UniProtKB/Swiss-Prot Summary for DGAT2 Gene
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 (PubMed:27184406). 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) (By similarity). Also able to use 1-monoalkylglycerol (1-MAkG) as an acyl acceptor for the synthesis of monoalkyl-monoacylglycerol (MAMAG) (PubMed:28420705).
Diacylglycerol O-Acyltransferases (DGATs), EC 220.127.116.11, are enzymes that catalyze the final step of triglyceride (TG) synthesis, the covalent attachment of fatty acyl-CoA and diacylglycerol (DAG). There have been two DGAT isoforms identified to date, DGAT1 and DGAT2.
