Hypoxia-inducible factor 1, alpha subunit (basic helix-loop-helix transcription factor), also known as HIF1A, is a protein that in humans is encoded by the HIF1A gene.^[1]^[2] Two alternative transcripts encoding different isoforms have been identified.^[3]

[edit] Structure

HIF1 is a homodimeric basic helix-loop-helix structure^[4] composed of Hif1a, the alpha subunit (this protein), and the aryl hydrocarbon receptor nuclear translocator (Arnt), the beta subunit.

[edit] Function

The protein encoded by HIF1 is a bHLH - PAS transcription factor found in mammalian cells growing at low oxygen concentrations. It plays an essential role in cellular and systemic responses to hypoxia.^[5] This is one of the class of hypoxia inducible factors, a family that includes Hif1a, Hif2a, and Hif3a.

[edit] Regulation

HIF-1alpha abundance (and its subsequent activity) is regulated transcriptionally in an NF-κB-dependent manner.^[6] In addition, the coordinated activity of the prolyl hydroxylases (PHDs) maintain the appropriate balance of HIF-1α protein in the post-translation phase.^[7]

PHDs rely on iron among other molecules to phosphorylate HIF-1alpha; as such, iron chelators such as DFO and DMOG have proven successful in HIF-1alpha stabilization.^{[citation needed]} HBO (Hyperbaric oxygen therapy) and HIF-1alpha imitators such as cobalt chloride have also been successfully utilized.^{[citation needed]}

Factors increasing HIF-1α^[8]

Modulator of Degradation:
- Oxygen-Dependent:
  - EPF UCP (degrades pHVL)
  - VDU2 (de-ubiquitinates HIF-1α)
  - SUMOylation (via RSUME)
  - DeSUMOylation ( via SENP1)
- Oxygen-independent:
  - Calcineurin A ( Ca2+-dependent via RACK1)
Modulators of translation:
- RNA-binding proteins, PTB, and HuR
- PtdIns3K and MAPK pathways
- IRES-mediated translation
- calcium signaling
- miRNAs

Factors decreasing HIF-1α^[8]

Modulator of Degradation:
- Oxygen-Dependent:
  - PHD, pVHL, OS-9 and SSAT2
  - SUMOylation
- Oxygen-independent
  - RACK1 and SSAT1
  - GSK3β
  - FOXO4
Modulators of translation:
- Calcium signaling
- miRNAs

[edit] Interactions

HIF1A has been shown to interact with pVHL,^[9] PSMA7,^[10] NR4A,^[11] STAT3,^[12] CREBB,^[13]^[14]^[15] ARNTL,^[16] ARNT,^[2]^[17] P53,^[18]^[19]^[20]^[21] EP300,^[22]^[23] HIF1AN,^[24] Mdm2,^[18]^[19] VH^[11]^[12]^[15]^[24]^[25]^[26]^[27]^[28]^[29]^[30] and UBC.^[11]^[15]^[30]

[edit] Clinical significance

Overexpression of a natural antisense transcript (aHIF) of this gene is associated with nonpapillary renal carcinomas.^[31]
