這個基因編碼的蛋白質是芳香烴的受體和配體激活的轉錄因子。編碼的蛋白質作為多蛋白復合物的一部分存在于細胞質中，但在配體結合后被轉運到細胞核。這種蛋白質可以調節許多外源代謝酶的表達。此外，編碼的蛋白可以特異性地結合并抑制乙型肝炎病毒的活性。已經發現了三個編碼不同亞型的轉錄變體。[由RefSeq提供，2014年12月]
The protein encoded by this gene is a receptor for aryl hydrocarbons and a ligand-activated transcription factor. The encoded protein is found in the cytoplasm as part of a multiprotein complex, but upon binding of ligand is transported to the nucleus. This protein can regulate the expression of many xenobiotic metabolizing enzymes. Also, the encoded protein can bind specifically to and inhibit the activity of hepatitis B virus. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2014]
