Hif 2 α
Web25 de fev. de 2024 · Hypoxia-inducible factor-1alpha (HIF-1 α ) is a major transcription factor that adapts to low oxygen homeostasis and regulates the expression of several hypoxic genes, which aid in cancer survival and development. It has recently piqued the interest of translational researchers in the disciplines of cancer sciences.

WebFurthermore, the oxygen-dependent degradation domains (ODD) in the two HIF-α subunits, including the two critical proline residues, exhibit a high degree of homology . Prolyl-hydroxylase domain (PHD) 2 binds to both HIF-α subtypes and catalyzes the hydroxylation of Pro-402 and Pro-564 in HIF-1α and Pro-405 and Pro-531 in HIF-2α. WebHypoxia inducible factors (HIFs) are transcriptional heterodimer complexes, consisting of an inducible α subunit (HIF-1α, HIF-2α and HIF-3α) and constitutively expressed β subunits. The family members HIF-1 and HIF-2 are regulators of oxygen homeostasis 68,69 , whereas the role of HIF-3 still remains unclear.
