WebApr 15, 1999 · Hypoxia-inducible factor-1 (HIF-1) is a master regulator of mammalian oxygen homeostasis. HIF-1 consists of two subunits, HIF-1alpha and the aryl hydrocarbon receptor nuclear translocator (ARNT). Whereas hypoxia prevents proteasomal degradation of HIF-1alpha, ARNT expression is thought to be oxygen-independent. WebThe aromatic hydrocarbon receptor protein, together with its heterodimerization partner, the aromatic hydrocarbon receptor nuclear translocator protein, mediates dioxin action. There are notable similarities between the mechanism of dioxin action and the mechanisms of steroid/retinoid/thyroid hormone action.

WebIn response to dioxin stimulation AhR can form an AhR–ARNT–ERα (estrogen receptor α) complex, which can activate ERα-responsive genes even in the absence of estrogen. On the other hand, ERα is less responsive to estrogen stimulation when it is in the AhR–ARNT–ERα complex. The ARNT gene encodes the aryl hydrocarbon receptor nuclear translocator protein that forms a complex with ligand-bound aryl hydrocarbon receptor (AhR), and is required for receptor function. The encoded protein has also been identified as the beta subunit of a heterodimeric transcription factor, hypoxia … See more Aryl hydrocarbon receptor nuclear translocator has been shown to interact with: • AIP, • AHR, • EPAS1, See more • Haase VH (2006).
