CC   -!- FUNCTION: Transcription factor that functions as an obligate
CC       heterodimerization partner for several basic helix-loop-helix PER-ARNT-
CC       SIM (bHLH-PAS) proteins. Forms heterodimers with the aryl hydrocarbon
CC       receptor (AHR) to mediate the transcriptional response to xenobiotics
CC       by binding xenobiotic response elements (XREs) or dioxin response
CC       elements (DREs) in target gene promoters. Also heterodimerizes with
CC       hypoxia-inducible factor alpha subunits (HIF1A, EPAS1, NPAS1 or NPAS3)
CC       to form hypoxia-inducible transcription factors that bind hypoxia
CC       response elements (HREs) and activate genes involved in cellular and
CC       systemic responses to hypoxia, including angiogenesis, erythropoiesis,
CC       and metabolic adaptation (By similarity). Plays a central role in
CC       environmental sensing and developmental and physiological regulation of
CC       gene expression (By similarity). {ECO:0000250|UniProtKB:P27540,
CC       ECO:0000250|UniProtKB:P53762}.
CC   -!- SUBUNIT: Monomer. Homodimer only upon binding to a DNA (By similarity).
CC       Efficient DNA binding requires dimerization with another bHLH-PAS
CC       protein. Interacts with TACC3 (By similarity). Interacts with HIF1A,
CC       EPAS1, NPAS1 and NPAS3; forms a heterodimer that binds core DNA
CC       sequence 5'-TACGTG-3' within the hypoxia response element (HRE) of
CC       target gene promoters (By similarity). Forms a heterodimer with AHRR,
CC       as well as with other bHLH-PAS proteins. Interacts with NOCA7 (By
CC       similarity). Interacts with TACC3 (By similarity). Interacts with
CC       AHR;The heterodimer ARNT:AHR binds to the dioxin response element (DRE)
CC       of target gene promoters and activates their transcription (By
CC       similarity). Interacts with SIM1 and NPAS4 (By similarity).
