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 ...
