Aryl hydrocarbon receptor pathway (Homo sapiens)
From WikiPathways
Description
The Aryl Hydrocarbon receptor (AhR) is ligand activated transcription factor that regulates wide spectrum of gene expression. The main mediator of AhR is 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) or polycyclic aromatic hydrocarbons which are widespread environmental pollutant causing a variety of severe health effects, e.g. immunosuppression, carcinogenesis and hepatotoxicity.
AhR is a member of basic helix-loop-helix-Per-Arnt-Sim (bHLH-PAS) superfamily of transcription factors. In the absence of ligand, the AhR can be found in the cytosol, bound to a dimer of the heat shock protein of 90 kDa (Hsp90) and the immunophilin-like protein, AIP (also known as XAP2 and ARA9). Upon ligand binding, the AHR translocates to the nucleus and binds with ARNT. The AHR/ARNT heterodimer binds to xenobiotic response elements and regulates a diverse set of genes
