HIF-1 is a heterodimer consisting of an alpha and a beta subunit, both belonging to the basic-helix-loop-helix Per-aryl hydrocarbon receptor nuclear translocator-Sim (PAS) family of transcription factors.
HIF-1 is a key component of a widely operative transcriptional response activated by hypoxia, cobaltous ions, and iron chelation.
HIF-1 activates transcription of hypoxia-inducible genes, including those encoding: erythropoietin, vascular endothelial growth (VEGF), heme oxygenase-1, inducible nitric oxide synthase, and the glycolytic enzymes aldolase A, enolase 1, lactate dehydrogenase A, phosphofructokinase I, and phosphoglycerate kinase 1.
The C-terminal of HIF-1 alpha binds to p300.
p300/CBP-HIF complexes participate in the induction of hypoxia-responsive genes, including VEGF.
Applications:Suitable for use in ELISA and Immunohistochemistry.
