Previous Symbols for AHRR Gene
The protein encoded by this gene participates in the aryl hydrocarbon receptor (AhR) signaling cascade, which mediates dioxin toxicity, and is involved in regulation of cell growth and differentiation. It functions as a feedback modulator by repressing AhR-dependent gene expression. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

GeneCards Summary for AHRR Gene
AHRR (Aryl-Hydrocarbon Receptor Repressor) is a Protein Coding gene. Among its related pathways are AhR pathway (WikiPathways) and AHR Pathway (Qiagen). GO annotations related to this gene include signal transducer activity and protein dimerization activity. An important paralog of this gene is HIF3A.
UniProtKB/Swiss-Prot for AHRR Gene
Mediates dioxin toxicity and is involved in regulation of cell growth and differentiation. Represses the transcription activity of AHR by competing with this transcription factor for heterodimer formation with the ARNT and subsequently binding to the xenobiotic response element (XRE) sequence present in the promoter regulatory region of variety of genes. Represses CYP1A1 by binding the XRE sequence and recruiting ANKRA2, HDAC4 and/or HDAC5. Autoregulates its expression by associating with its own XRE site.
