Summary

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. [provided by RefSeq, Jul 2020]

Forensic Context

A study in a Wistar rat model of acute carbon dioxide poisoning demonstrated that the NR1I3 mRNA expression levels in the hypothalamus were not significantly different between any experimental CO2 exposure groups and the control group [Sato et al. DOI:10.1016/J.Legalmed.2015.07.014]. A study in human myocardial samples from explanted hearts demonstrated that the NR1I3 mRNA expression was significantly upregulated in dilated cardiomyopathy (8.16-fold, p < 0.0002) and ischemic cardiomyopathy (4.33-fold, p < 0.002) compared to a healthy control group [Tatrai et al. DOI:10.1016/J.Forsciint.2011.05.010].
