Dgat2 Gene Summary [Rat]
Enables diacylglycerol O-acyltransferase activity. Involved in diacylglycerol metabolic process; regulation of primary metabolic process; and response to nutrient. Predicted to be located in several cellular components, including lipid droplet; mitochondrion; and perinuclear endoplasmic reticulum membrane. Predicted to be active in endoplasmic reticulum membrane. Used to study steatotic liver disease. Biomarker of chronic kidney disease and metabolic dysfunction-associated steatotic liver disease. Human ortholog(s) of this gene implicated in metabolic dysfunction-associated steatotic liver disease. Orthologous to human DGAT2 (diacylglycerol O-acyltransferase 2).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Dgat2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
