Previous GeneCards Identifiers for AHR Gene
This gene encodes a ligand-activated transcription factor involved in the regulation of biological responses to planar aromatic hydrocarbons. This receptor has been shown to regulate xenobiotic-metabolizing enzymes such as cytochrome P450. Its ligands included a variety of aromatic hydrocarbons. [provided by RefSeq, Jul 2008]
GeneCards Summary for AHR Gene
AHR (Aryl Hydrocarbon Receptor) is a Protein Coding gene. Diseases associated with AHR include eosinophilic fasciitis and toxic oil syndrome. Among its related pathways are AhR pathway (WikiPathways) and AHR Pathway (Qiagen). GO annotations related to this gene include sequence-specific DNA binding transcription factor activity and protein heterodimerization activity. An important paralog of this gene is AHRR.
UniProtKB/Swiss-Prot for AHR Gene
Ligand-activated transcriptional activator. Binds to the XRE promoter region of genes it activates. Activates the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes (such as the CYP1A1 gene). Mediates biochemical and toxic effects of halogenated aromatic hydrocarbons. Involved in cell-cycle regulation. Likely to play an important role in the development and maturation of many tissues. Regulates the circadian clock by inhibiting the basal and circadian expression of the core circadian component PER1. Inhibits PER1 by repressing the CLOCK-ARNTL/BMAL1 heterodimer mediated transcriptional activation of PER1.
Aryl hydrocarbon receptors (AHRs) are cytosolic transcription factors that exist bound to co-chaperones in the resting state (Hsp90, prostaglandin E synthase 3 and hepatitis B virus X-associated protein 2). Ligand binding causes the co-chaperones to dissociate, allowing AHR to translocate to the nucleus, dimerize with AHR nuclear translocator (ARNT) and alter transcription of target genes. AHR is an evolutionary conserved receptor that has roles in cell proliferation and differentiation and induction of xenobiotic-metabolizing enzymes (for example CYP1A1). The human gene encoding the aryl hydrocarbon receptor has been localized to chromosome 7p15.
