Also known as: ARAT; HMFN1045; GS1999FULL
Summary: 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]

A binding assay utilizing (125)I-labeled imidazopyridine demonstrated that the level of imidazopyridine binding to DGAT2 mutant enzymes, H161A and H163A, dramatically decreased to 11-17% of that of the wild-type enzyme, indicating that these residues are critical for imidazopyridines to bind to DGAT2.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
