Web20 de ago. de 2024 · In the absence of O 2, HIF-α is no longer hydroxylated and ubiquitinated, thereby escaping from proteasomal degradation. Upon stabilization, HIF-α dimerizes with the HIF-1β subunit in the nucleus, and the heterodimeric HIF binds the hypoxia response element (5′-A/GCGTG-3′, HRE) to enhance gene transcription.
