Biological function summary

HIF prolyl hydroxylases play an essential role in oxygen sensing and homeostasis by regulating the activity of HIF-α subunits. Under normoxic conditions the hydroxylation of HIF-α by these hydroxylases permits recognition by the von Hippel-Lindau (VHL) protein leading to proteasomal degradation. In hypoxic conditions the decreased activity of HIF prolyl hydroxylases allows HIF-α stabilization and heterodimerization with HIF-β facilitating transcription of target genes involved in angiogenesis and metabolism. PHD2 is predominantly responsible for targeting HIF-1α.

Pathways

HIF prolyl hydroxylases integrate into the hypoxia response pathway. Oxygen-dependent regulation of HIF by these hydroxylases affects processes such as angiogenesis and erythropoiesis through interaction with several proteins including endothelial growth factor (VEGF) and erythropoietin (EPO). Beyond the hypoxia pathway they participate in metabolic pathways influencing cellular energy homeostasis thereby impacting proteins involved in metabolic regulation.
