Hif and hypoxia
WebHypoxia-inducible factors (HIFs) control transcriptional responses to reduced O2 availability. HIFs are heterodimeric proteins composed of an O2-regulated HIF-α subunit and a constitutively expressed HIF-1β subunit. HIF-α subunits are subject to prolyl hydroxylation, which targets the proteins for degradation under normoxic conditions.
