Previous GeneCards Identifiers for NR1H3 Gene
The protein encoded by this gene belongs to the NR1 subfamily of the nuclear receptor superfamily. The NR1 family members are key regulators of macrophage function, controlling transcriptional programs involved in lipid homeostasis and inflammation. This protein is highly expressed in visceral organs, including liver, kidney and intestine. It forms a heterodimer with retinoid X receptor (RXR), and regulates expression of target genes containing retinoid response elements. Studies in mice lacking this gene suggest that it may play an important role in the regulation of cholesterol homeostasis. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]
GeneCards Summary for NR1H3 Gene
NR1H3 (Nuclear Receptor Subfamily 1 Group H Member 3) is a Protein Coding gene. Among its related pathways are Gene Expression and Nuclear Receptor transcription pathway. GO annotations related to this gene include transcription factor activity, sequence-specific DNA binding and transcription coactivator activity. An important paralog of this gene is NR4A2.
UniProtKB/Swiss-Prot for NR1H3 Gene
Nuclear receptor. Interaction with RXR shifts RXR from its role as a silent DNA-binding partner to an active ligand-binding subunit in mediating retinoid responses through target genes defined by LXRES. LXRES are DR4-type response elements characterized by direct repeats of two similar hexanuclotide half-sites spaced by four nucleotides. Plays an important role in the regulation of cholesterol homeostasis, regulating cholesterol uptake through MYLIP-dependent ubiquitination of LDLR, VLDLR and LRP8. Interplays functionally with RORA for the regulation of genes involved in liver metabolism (By similarity). Exhibits a ligand-dependent transcriptional activation activity (PubMed:25661920).
Liver X receptors (LXRs) and farnesoid X receptors (FXRs) are members of the steroid analog-activated nuclear receptor subfamily, which form heterodimers with members of the retinoid X receptor family. There are two closely related isoforms of each of these enzymes; alpha and beta.
