HIF prolyl-hydroxylase

HIF prolyl-hydroxylase is an enzyme involved in the HIF (Hypoxia-inducible factor) signalling pathways, and is the target for a set of therapeutic drugs called HIF prolyl-hydroxylase inhibitors.

Hypoxia-inducible factor (HIF) is an evolutionarily conserved transcription factor[1] that allows the cell to respond physiologically to low concentrations of oxygen.[2] A class of prolyl hydroxylases which act specifically on HIF has been identified;[3] hydroxylation of HIF allows the protein to be targeted for degradation.[3] HIF prolyl-hydroxylase has been targeted by a variety of inhibitors that aim to treat stroke,[4] kidney disease,[5] ischemia,[6] anemia,[7] and other important diseases.
