The Aryl hydrocarbon Receptor (AhR) also known as the Ah receptor is a ligand-activated transcription factor expressed in various tissues including liver lung and skin. The AhR has a molecular mass of approximately 96 kDa. It forms a complex with the aryl hydrocarbon receptor nuclear translocator (ARNT) upon ligand binding. AhR can bind to several compounds including aryl azide influencing the expression of numerous genes involved in xenobiotic metabolism.

Biological function summary

The AhR plays an important role in the regulation of detoxification enzymes such as cytochrome P450s. This receptor functions as a sensor for environmental toxins activating detoxification pathways once bound to ligands. It also contributes to the modulation of immune responses and development processes. The AhR often forms part of a larger protein complex to exert its effects on gene expression and cellular processes.

Pathways

The AhR significantly participates in the xenobiotic metabolism pathway and the dioxin signaling pathway. It interacts with proteins such as ARNT and cytochrome P450 enzymes to mediate the cellular response to toxins. The activity of AhR regulates the expression of phase I and phase II detoxification enzymes making it an integral part of the body’s defense against environmental chemicals.

Disturbances in AhR activity have been linked to cancer and autoimmune diseases. Altered expression or function of AhR can contribute to aberrant cell proliferation and immune dysregulation. The AhR interacts with other proteins like peroxidase and its substrates playing a role in oxidative stress responses associated with these conditions. Understanding these links can offer insights into therapeutic targets for related diseases.
