Oxygen is absolutely critical for the survival of mammalian cells.
Hypoxia induced factor (HIF) is a transcriptional complex that plays a central role in mammalian oxygen homeostasis.
There are 3-types of alpha subunits (HIF1-3alpha) and one HIF-beta subunits.
However, the three HIF-alpha subunits are regulated by oxygen in a similar fashion, i.e.
by regulated stabilization of the alpha-subunits.
Under normal conditions, HIF-alpha Prolines are hydroxylated at Pro-402 and Pro-564.
This allows binding of von Hippel-Lindau (VHL), the substrate recognition component of the E3 ubiquinated ligase complex, subsequent ubiquitination and degradation of HIF-alpha by the proteasome.
Under hypoxic conditions, hydroxylation of HIF-alpha is inhibited and this prevents HIF-alpha degradation.
The enzymes responsible for HIF-hydroxylation are known as HIF-prolyl hydroxylases (PHD1-3 or HPH1, HPH2, and HPH3).
The three PHDs have been identified to hydroxylate the motif, LXXLAP* with *P being the hydroxyproline.
PHD1 (human 407-aa, chromosome 19; also known as Egl nine homolog 2, EGLN2 (Hypoxia-inducible factor prolyl hydroxylase 1) (HIF-prolyl hydroxylase 1) (HIF-PH1) (HPH-3) (Prolyl hydroxylase domain-containing protein 1) (PHD1) (Estrogen-induced tag 6) is a hydroxylates HIF-1 alpha at Pro-402 and Pro-564, and HIF-2 alpha.
PHD1 is expressed abundantly in all tissues with highest expression in testis.
It is expressed in hormone responsive tissues, including normal and cancerous mammary, ovarian and prostate epithelium.
