Web1 de abr. de 2024 · HIFs are heterodimers consisting of an oxygen-labile HIFα subunit, either HIF1α or HIF2α, and a constitutive HIF1β subunit. In the presence of oxygen, HIF1/2α is hydroxylated by specific prolyl hydroxylases (PHD), facilitating binding of von Hippel–Lindau protein (VHL), ubiquitylation, and proteasomal degradation.
