HIF prolyl 4-hydroxylases (HIF-P4Hs or PHDs) are proyl hydroxylase domain-containing enzymes (PHD1, PHD2, PHD3, and P4H-TM) that mediate key physiological responses to hypoxia by modulating HIF1 alpha levels. PHD member proteins have a wide but varied tissue expression and PHD4/HIF Prolyl Hydroxylase 4 (P4H-TM) is a novel member of this family that localize to ER membrane as single-pass type II membrane protein with its catalytic site inside the lumen. P4H-TM is expressed mainly in pancreas, heart, skeletal muscle, brain, placenta, kidney and adrenal gland tissues and gets induced upon hypoxic trigger. P4H-TM catalyzes the post-translational formation of 4-hydroxyproline in HIF alpha proteins and hydroxylates HIF1A at 'Pro-402'/'Pro-564' sites. P4H-TM has been proposed to function as a cellular oxygen sensor and, under normoxic conditions, it targets HIF through hydroxylation for proteasomal degradation via VHL/von Hippel-Lindau ubiquitination complex. Ectopic over-expression of P4H-TM in cultured neuroblastoma cells was found to reduce HIF-1alpha ODDD reporter levels, whereas its knockdown increased HIF-1alpha protein levels. HIF-P4Hs plays a critical role in several pathologies such as myocardial infarction, stroke, peripheral vascular disease, inflammation, diabetes, carcinogenesis and severe anemias.
