UniProt code: P45448.

Organism: Mus musculus (Mouse).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Mus; Mus.
 
Function: Nuclear receptor that acts as a key metabolic sensor by regulating the expression of genes involved in bile acid synthesis, cholesterol homeostasis and triglyceride synthesis. Together with the oxysterol receptors NR1H3/LXR-alpha and NR1H2/LXR-beta, acts as an essential transcriptional regulator of lipid metabolism. Plays an anti- inflammatory role during the hepatic acute phase response by acting as a corepressor: inhibits the hepatic acute phase response by preventing dissociation of the N-Cor corepressor complex. Key regulator of cholesterol 7-alpha-hydroxylase gene (CYP7A) expression in liver. May also contribute to the regulation of pancreas-specific genes and play important roles in embryonic development (By similarity). Activates the transcription of CYP2C38 (PubMed:30555544). {ECO:0000250|UniProtKB:O00482, ECO:0000269|PubMed:30555544}.
 
Subunit: Binds DNA as a monomer (By similarity). Interacts with GRIP1, NCOA2 and NR0B2 (PubMed:12820970, PubMed:15976031). Interacts (when sumoylated) with GPS2; interaction with GPS2 onto hepatic acute phase protein promoters prevents N-Cor corepressor complex dissociation (By similarity). {ECO:0000250|UniProtKB:O00482, ECO:0000269|PubMed:12820970, ECO:0000269|PubMed:15976031}.
Subcellular location: Nucleus {ECO:0000250|UniProtKB:O00482}.
Ptm: Sumoylated by SUMO1 at Lys-289 during the hepatic acute phase response, leading to promote interaction with GPS2 and prevent N-Cor corepressor complex dissociation. {ECO:0000250|UniProtKB:O00482}.
Similarity: Belongs to the nuclear hormone receptor family. NR5 subfamily. {ECO:0000305}.
