Web15 de jul. de 2024 · Section snippets Hypoxic signalling by the HIFs. The heterodimeric HIF transcription factors, members of the basic helix-loop-helix Per-Arnt-Sim (bHLH-PAS) family, are composed of an oxygen-regulated HIF-α subunit and a constitutively active aryl hydrocarbon receptor nuclear translocator (Arnt) subunit (also known as HIF-β) that form … Web6 de jun. de 2015 · Both types of HIF hydroxylase are members of the Fe(II) and 2-oxoglutarate dependent dioxygenase superfamily. Catalysis couples the oxidation (hydroxylation) of HIFalpha to the oxidative decarboxylation of 2-oxoglutarate to succinate and carbon dioxide (for review see 15).This process is inhibited by hypoxia allowing …
