  • contained a region as essential for nuclear export in their N-terminal region
  • a zinc finger MYND type
  • a PKHD (prolyl/lysyl hydroxylase) domain
  • a catalytic domain with potential to react with nitric oxide both at its Fe(II) and at cysteine residues

    basic FUNCTION
  • catalyzing the posttranslational formation of 4- hydroxyproline in hypoxia-inducible factor (HIF) alpha proteins
  • regulator of hypoxia-inducible factor HIF alpha 1 subunit by prolylhydroxylation and targeting it to proteasome degradation
  • important mediator of neurotrophin withdrawal- mediated cell death
  • contributing in a non-redundant manner to the regulation of both HIF-1alpha and HIF-2alpha subunits
  • its regulation is an effective pathway for the control of the hypoxic response
  • enzyme mostly responsible for oxygen-induced degradation of HIF-A proteins
  • may function as a tumor suppressor gene in pancreatic cancer
  • serves as an oxygen sensor that rescues blood supply by regulating vessel formation and shape in case of oxygen shortage
  • regulates arteriogenesis and artery homeostasis by controlling a specific differentiation state in macrophages
  • oxygen/redox-sensitive enzyme that induces cellular adaptations to stress conditions
  • plays a pivotal role in the HIF pathway and has emerged as one of the most intriguing genes with respect to physiology at HA (high altitude)
  • EGLN3 with EGLN1, EGLN2 are cellular oxygen sensors that can mark HIF1A for von Hippel-Lindau protein-mediated proteasomal destruction
