4. prolyl 4-hydroxylase domain(English)

   • the concentration of cytosolic oxygen is sensed by these proteins that act on HIF-1α. Under normoxia, they hydroxylate two highly conserved proline residues (Pro402 and Pro564) located within the oxygen-dependent degradation domain. There are three isoforms
   • HIF-1α, pVHL, ODDD
   • Oxygen
