== Function ==
== Function ==
[[http://www.uniprot.org/uniprot/ARNT_HUMAN ARNT_HUMAN]] Required for activity of the Ah (dioxin) receptor. This protein is required for the ligand-binding subunit to translocate from the cytosol to the nucleus after ligand binding. The complex then initiates transcription of genes involved in the activation of PAH procarcinogens. The heterodimer with HIF1A or EPAS1/HIF2A functions as a transcriptional regulator of the adaptive response to hypoxia. [[http://www.uniprot.org/uniprot/AHR_MOUSE AHR_MOUSE]] Ligand-activated transcriptional activator. Binds to the XRE promoter region of genes it activates. Activates the expression of multiple phase I and II xenobiotic chemical metabolizing enzyme genes (such as the CYP1A1 gene). Mediates biochemical and toxic effects of halogenated aromatic hydrocarbons. Involved in cell-cycle regulation. Likely to play an important role in the development and maturation of many tissues.<ref>PMID:1314586</ref> <ref>PMID:7961644</ref> <ref>PMID:7969080</ref> <ref>PMID:8806883</ref> <ref>PMID:9427285</ref> <ref>PMID:10973493</ref> <ref>PMID:10639156</ref>
