Nr1h4 Gene Summary [Rat]
Enables several functions, including DNA-binding transcription factor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chenodeoxycholic acid binding activity. Contributes to double-stranded DNA binding activity. Involved in several processes, including cellular response to bile acid; cholesterol homeostasis; and regulation of biosynthetic process. Part of receptor complex. Used to study extrahepatic cholestasis; intrahepatic cholestasis; and portal hypertension. Biomarker of bile duct disease (multiple); liver disease (multiple); and obesity. Human ortholog(s) of this gene implicated in extrahepatic cholestasis; hepatocellular carcinoma; and progressive familial intrahepatic cholestasis 5. Orthologous to human NR1H4 (nuclear receptor subfamily 1 group H member 4). [provided by Alliance of Genome Resources, Apr 2025]

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 Nr1h4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
