芳香族炭化水素受容体核内輸送体ARNT: aryl hydrocarbon receptor nuclear translocator)は、リガンド結合型芳香族炭化水素受容体(AhR)と複合体を形成するタンパク質であり、AhRが受容体として機能するために必要である。また、低酸素誘導因子1(HIF1)のベータサブユニットとしても知られている。TEL-ARNT融合タンパク質の発現をもたらす遺伝子座のt(1; 12)(q21; p13)転座は、急性骨髄芽球性白血病と関連している。この遺伝子について、異なるアイソフォームをコードする3つのスプライスバリアントが報告されている。

AhRは、生体異物代謝に関与するいくつかの酵素の誘導に関与している。リガンドを含まない、細胞質ゾル型のAhRは、熱ショックタンパク質90(Hsp90)と複合体を形成する。ダイオキシン多環芳香族炭化水素を含むリガンドの結合は、リガンド結合サブユニットの核への転座をもたらす[5]。生体異物代謝に関与する酵素の誘導は、これら酵素の遺伝子のプロモーター内の生体異物応答エレメントへのリガンド結合型AhRの結合を介して発生する。
