HIF-1 is a heterodimer composed of HIF-1 alpha and HIF-1 beta subunits which are bHLH proteins of PAS (PER, ARNT, SIM) family. HIF-1 beta forms heterodimer with AHR, AHRR, HIF1 alpha and EPAS1/HIF2 alpha as well as with other bHLH proteins and its dimerization is required for efficient DNA binding. It has been shown to interact with TACC3 and NOCA7 also. HIF-1 beta is also known as ARNT (AhR nuclear translocator) due to its ability to partner with AhR to form a heterodimeric transcription factor complex which is required for AhR activity. It is essential for the ligand-binding subunit to translocate from the cytosol to the nucleus after ligand binding and the AhR-HIF-1 beta complex then initiates transcription of genes involved in xenobiotic transformation, especially of PAHs. HIF-1 beta heterodimer with HIF1 alpha or EPAS1/HIF2 alpha functions as a transcriptional regulator of the adaptive response to hypoxia. Moreover, a chromosomal translocation resulting in TEL-ARNT fusion protein is associated with AML (acute myeloblastic leukemia) and decreased HIF-1 beta expression levels in pancreatic islets from NIDDM subjects reflects its important role in beta-cell function.
