Hif 1 α

WebRegulation of HIF-1α stability can also be mediated by an oxygen-independent pathway. In the cytoplasm, HIF-1α is bound to heat-shock protein 90 (Hsp90), leading to enhanced HIF-1α stability. Displacement if Hsp90 by inhibitors allows RACK (receptor of activated protein C kinase) to bind and recruit ubiquitin ligase machinery, leading to HIF ...

WebStructure of hypoxia inducible factor 1-α (HIF-1α). The NH2-terminal of HIF-1α and HIF-1β consists of bHLH (basic helix–loop–helix) and PAS (Per-ARNT-Sim homology) domains that are required for heterodimerization and DNA binding. The COOH-terminal of HIF-1α (residues 531–826) contains two transactivation domains (TADs).
