WebHIFs mainly control transcription of genes for angiogenesis, erythropoiesis and glycolysis in response to hypoxia. In normoxia HIF-α’s are constantly degraded. Degradation is prevented in hypoxia, the HIF-α’s form heterodimers with HIF-β’s, translocate to the nucleus and become transcriptionally active.
