The aryl-hydrocarbon receptor repressor also known as AHRR is a human gene.[1]



Dioxin is a teratogen that exerts its effects through the aryl hydrocarbon receptor (AhR) in conjunction with the receptor's binding partner, aryl hydrocarbon receptor nuclear translocator (ARNT). The protein encoded by this gene represses signal transduction by the AhR by competing with the ARNT for binding to the arylhydrocarbon receptor.[2] Expression of the repressor is stimulated by the receptor/translocator heterodimer, thereby regulating receptor function through a negative feedback mechanism. In addition, the encoded protein can bind to nuclear factor-kappa B.

The AhRR gene may act as a tumor suppressor.[3][4]

Tissue distribution

The expression of AhRR is high in testis, lung, ovary, spleen and pancreas in adults, whereas expression is low in all tissues in fetuses.[5]
