Under normal oxygen tension, HIF-1 α protein expression is negatively regulated by proteasomal degradation and ubiquitination in a pathway involving von Hippel−Lindau protein (pVHL), a tumor suppressor protein and one of the recognized components of an E3 ubiquitin protein ligase 27. Web18 de set. de 2024 · The HIF-1 complex is a heterodimer composed of two basic helix-loop-helix subunits: the HIF-1α and the HIF-1β subunits. HIF-1 β is constitutively expressed whereas HIF-1 α activity is posttranscriptionally regulated by O 2 sensors and O 2 -dependent enzymes including prolyl hydroxylases (PHDs) [ 6 , 7 ].
