WebThe prolyl hydroxylase domain (PHD) / hypoxia-inducible factor (HIF) axis is a critically important oxygen-sensing pathway that mediates tissue adaptation to low oxygen environments primarily via the transcriptional … WebMutations in the EPAS1 gene change single protein building blocks (amino acids) in the HIF-2α protein. These changes prevent HIF-2α from interacting normally with the proteins that target it for degradation. As a result, HIF-2α is not degraded efficiently, and HIF accumulates in cells even when adequate oxygen is available.
