The aryl hydrocarbon receptor (AhR or AHR) is a protein that in humans is encoded by the AHR gene. The aryl hydrocarbon receptor is 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.The aryl hydrocarbon receptor is a member of the family of basic helix-loop-helix transcription factors.
