Summary: Enables 2-acylglycerol O-acyltransferase activity and diacylglycerol O-acyltransferase activity. Involved in several processes, including acylglycerol metabolic process; fatty acid homeostasis; and long-chain fatty-acyl-CoA metabolic process. Located in intracellular membrane-bounded organelle and membrane. Is active in endoplasmic reticulum membrane. Is expressed in several structures, including brain; genitourinary system; liver; skin; and yolk sac. Human ortholog(s) of this gene implicated in cardiomyopathy and congenital diarrhea 7 with exudative enteropathy. Orthologous to human DGAT1 (diacylglycerol O-acyltransferase 1).

Study demonstrated that Dgat1-/- mice have alterations in the process of autophagy-mediated cytoplasmic liquid droplets mobilization in enterocytes, likely due to the impairments of autophagic vesicles turnover and lysosome acidification during early stage of dietary fat absorption.
Title: DGAT1 deficiency disrupts lysosome function in enterocytes during dietary fat absorption.
Study shows that inactivation of DGAT1 or DGAT2 in adult mouse heart results in a moderate suppression of triglycerides (TG) synthesis and turnover. Partial inhibition of DGAT activity increases cardiac fatty acid oxidation without affecting PPARalpha signaling, myocardial energetics or contractile function. Thus, the two DGAT isoforms in the heart have partially redundant function.

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.
