Summary

NR1I3 (nuclear receptor subfamily 1 group I member 3, HGNC:7969) is a protein-coding gene on chromosome 1q23.3, encoding Nuclear receptor subfamily 1 group I member 3 (Q14994). Binds and transactivates the retinoic acid response elements that control expression of the retinoic acid receptor beta 2 and alcohol dehydrogenase 3 genes.

This gene encodes a member of the nuclear receptor superfamily, and is a key regulator of xenobiotic and endobiotic metabolism. The protein binds to DNA as a monomer or a heterodimer with the retinoid X receptor and regulates the transcription of target genes involved in drug metabolism and bilirubin clearance, such as cytochrome P450 family members. Unlike most nuclear receptors, this transcriptional regulator is constitutively active in the absence of ligand but is regulated by both agonists and inverse agonists. Ligand binding results in translocation of this protein to the nucleus, where it activates or represses target gene transcription. These ligands include bilirubin, a variety of foreign compounds, steroid hormones, and prescription drugs. In addition to drug metabolism, the CAR protein is also reported to regulate genes involved in glucose metabolism, lipid metabolism, cell proliferation, and circadian clock regulation. Multiple transcript variants encoding different isoforms have been found for this gene.

UniProt curated annotations — full annotation on UniProt →

Function. Binds and transactivates the retinoic acid response elements that control expression of the retinoic acid receptor beta 2 and alcohol dehydrogenase 3 genes. Transactivates both the phenobarbital responsive element module of the human CYP2B6 gene and the CYP3A4 xenobiotic response element.

Subunit / interactions. Interacts with ECT2. Heterodimer of NR1I3 and RXR. Interacts with PSMC4. Directly interacts with DNAJC7. The DNAJC7-NR1I3 complex may also include HSP90. Interacts with CRY1. Interacts with CRY2 in a ligand-dependent manner.

Subcellular location. Nucleus. Cytoplasm. Cytoskeleton.

Tissue specificity. Predominantly expressed in liver.

Post-translational modifications. Phosphorylated at Thr-38 by PKC, dephosphorylation of Thr-38 is required for nuclear translocation and activation.

Domain organisation. Composed by a short N-terminal domain followed by the DNA binding, hinge, and ligand binding/dimerization domains.

Induction. By dexamethasone.

Similarity. Belongs to the nuclear hormone receptor family. NR1 subfamily.
