Protein Information (annotations from UniProt)

Database IDHIV0000797
UniProt IDO75907
Primary gene name(s)DGAT1
Synonym gene name(s)AGRP1, DGAT
Protein nameDiacylglycerol O-acyltransferase 1
Protein functionCatalyzes the terminal and only committed step in triacylglycerol synthesis by using diacylglycerol and fatty acyl CoA as substrates. In contrast to DGAT2 it is not essential for survival. May be involved in VLDL, very low density lipoprotein assembly. In liver, plays a role in esterifying exogenous fatty acids to glycerol. Functions as the major acyl-CoA retinol acyltransferase, ARAT in the skin, where it acts to maintain retinoid homeostasis and prevent retinoid toxicity leading to skin and hair disorders. {ECO:0000269|PubMed:16214399, ECO:0000269|PubMed:9756920}.
Subcellular locationEndoplasmic reticulum membrane {ECO:0000250|UniProtKB:Q9Z2A7};
Multi-pass membrane protein {ECO:0000250|UniProtKB:Q9Z2A7}.
