The protein encoded by this gene represses signal transduction by the AhR by competing with the arylhydrocarbon receptor for binding to the ARNT.[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 distributionThe expression of AhRR is high in testis, lung, ovary, spleen and pancreas in adults, whereas expression is low in all tissues in fetuses.[5] {{Clear}}References1. ^{{cite journal | vauthors = Baba T, Mimura J, Gradin K, Kuroiwa A, Watanabe T, Matsuda Y, Inazawa J, Sogawa K, Fujii-Kuriyama Y | title = Structure and expression of the Ah receptor repressor gene | journal = J.
