Alternate Names	ARNT interacting protein ARNT-interacting protein Basic-helix-loop-helix-PAS protein MOP1 HIF-1 alpha HIF1 alpha Member of PAS protein 1 hypoxia inducible factor 1, alpha subunit (basic helix-loop-helix transcription factor) hypoxia-inducible factor 1, alpha subunit hypoxia-inducible factor 1, alpha subunit (basic helix-loop-helix transcription factor) member of PAS superfamily 1
Background Information	Cell growth and viability is compromised by oxygen deprivation (hypoxia). Hypoxia-inducible factors, including HIF-1α, HIF-1β (also designated Arnt 1), EPAS-1 (also designated HIF-2α) and HIF-3α, induce glycolysis, erythropoiesis and angiogenesis in order to restore oxygen homeostasis. Hypoxia-inducible factors are members of the Per-Arnt-Sim (PAS) domain transcription factor family. In response to hypoxia, HIF-1α is upregulated and forms a heterodimer with Arnt 1 to form the HIF-1 complex. The HIF-1 complex recognizes and binds to the hypoxia responsive element (HRE) of hypoxia-inducible genes, thereby activating transcription. Hypoxia-inducible expression of some genes such as Glut-1, p53, p21 or Bcl-2, is HIF-1α dependent, whereas expression of others, such as p27, GADD 153 or HO-1, is HIF-1α independent. EPAS-1 and HIF-3α have also been shown to form heterodimeric complexes with Arnt 1 in response to hypoxia.

Entrez Gene Summary	Hypoxia-inducible factor-1 (HIF1) is a transcription factor found in mammalian cells cultured under reduced oxygen tension that plays an essential role in cellular and systemic homeostatic responses to hypoxia. HIF1 is a heterodimer composed of an alpha subunit and a beta subunit. The beta subunit has been identified as the aryl hydrocarbon receptor nuclear translocator (ARNT). This gene encodes the alpha subunit of HIF-1. Overexpression of a natural antisense transcript (aHIF) of this gene has been shown to be associated with nonpapillary renal carcinomas. Two alternative transcripts encoding different isoforms have been identified. [provided by RefSeq].

Purification Method	Affinity Purfied
UniProt Number	Q16665
UniProt Summary	FUNCTION: Functions as a master transcriptional regulator of the adaptive response to hypoxia. Under hypoxic conditions activates the transcription of over 40 genes, including, erythropoietin, glucose transporters, glycolytic enzymes, vascular endothelial growth factor, and other genes whose protein products increase oxygen delivery or facilitate metabolic adaptation to hypoxia. Plays an essential role in embryonic vascularization, tumor angiogenesis and pathophysiology of ischemic disease. Binds to core DNA sequence 5'-[AG]CGTG-3' within the hypoxia response element (HRE) of target gene promoters. Activation requires recruitment of transcriptional coactivators such as CREBPB and EP300. Activity is enhanced by interaction with both, NCOA1 or NCOA2. Interaction with redox regulatory protein APEX seems to activate CTAD and potentiates activation by NCOA1 and CREBBP. SIZE: 826 amino acids; 92670 Da SUBUNIT: Interacts with COPS5 subunit of COP9 signalosome complex, leading to the regulation of its stability. Interacts with TSGA10 (By similarity). Efficient DNA binding requires heterodimerization of an alpha and a beta/ARNT subunit. Binds to the TAZ-type 1 domains of CREBBP and EP300. Interacts with NCOA1, NCOA2, APEX and HSP90. Interacts with VHL which docks HFA1 to the E3 ubiquitin ligase complex for subsequent destruction. Interaction, via the ODD domain, with the beta domain of VHLL, protects HIF1A from destruction by competing against the destructive targeting initiated by VHL. SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Cytoplasmic in normoxia, nuclear translocation in response to hypoxia. TISSUE SPECIFICITY: Expressed in most tissues with highest levels in kidney and heart. Overexpressed in the majority of common human cancers and their metastases, due to the presence of intratumoral hypoxia and as a result of mutations in genes encoding oncoproteins and tumor suppressors. DOMAIN: Contains two independent C-terminal transactivation domains, NTAD and CTAD, which function synergistically. Their transcriptional activity is repressed by an intervening inhibitory domain (ID). PTM: In normoxia, is hydroxylated on Pro-402 and Pro-564 in the oxygen-dependent degradation domain (ODD) by EGLN1/PHD1 and EGLN2/PHD2. EGLN3/PHD3 has also been shown to hydroxylate Pro-564. The hydroxylated prolines promote interaction with VHL, initiating rapid ubiquitination and subsequent proteasomal degradation. Under hypoxia, proline hydroxylation is impaired and ubiquitination is attenuated, resulting in stabilization. & In normoxia, is hydroxylated on Asn-803 by HIF1AN, thus abrogating interaction with CREBBP and EP300 and preventing transcriptional activation. & S-nitrosylation of Cys-800 may be responsible for increased recruitment of p300 coactivator necessary for transcriptional activity of HIF-1 complex. & Acetylation of Lys-532 by ARD1 increases interaction with VHL and stimulates subsequent proteasomal degradation. & Requires phosphorylation for DNA-binding.
