| + | [https://www.uniprot.org/uniprot/HIF1N_HUMAN HIF1N_HUMAN] Hydroxylates HIF-1 alpha at 'Asp-803' in the C-terminal transactivation domain (CAD). Functions as an oxygen sensor and, under normoxic conditions, the hydroxylation prevents interaction of HIF-1 with transcriptional coactivators including Cbp/p300-interacting transactivator. Involved in transcriptional repression through interaction with HIF1A, VHL and histone deacetylases. Hydroxylates specific Asn residues within ankyrin repeat domains (ARD) of NFKB1, NFKBIA, NOTCH1, ASB4, PPP1R12A and several other ARD-containing proteins. Also hydroxylates Asp and His residues within ARDs of ANK1 and TNKS2, respectively. Negatively regulates NOTCH1 activity, accelerating myogenic differentiation. Positively regulates ASB4 activity, promoting vascular differentiation.<ref>PMID:12080085</ref> <ref>PMID:12042299</ref> <ref>PMID:17003112</ref> <ref>PMID:18299578</ref> <ref>PMID:19245366</ref> <ref>PMID:17573339</ref> <ref>PMID:21251231</ref> <ref>PMID:21177872</ref> | ||

A set of four non-heme iron(II) and 2-oxoglutarate-dependent enzymes catalyze the post-translational modification of a transcription factor, hypoxia inducible factor (HIF), that mediates the hypoxic response in animals. Hydroxylation of HIF both causes its degradation and limits its activity. We describe how the use of structural data coupled to solid-phase synthesis led to the discovery of a selective inhibitor of one of the HIF hydroxylases. The inhibitor N-oxalyl-d-phenylalanine was shown to inhibit the HIF asparaginyl hydroxylase (FIH) but not a HIF prolyl hydroxylase. A crystal structure of the inhibitor complexed to FIH reveals that it binds in the 2OG and, likely, in the dioxygen binding site. The results will help to enable the modulation of the hypoxic response for the up-regulation of specific genes of biomedical importance, such as erythropoietin and vascular endothelial growth factor. | A set of four non-heme iron(II) and 2-oxoglutarate-dependent enzymes catalyze the post-translational modification of a transcription factor, hypoxia inducible factor (HIF), that mediates the hypoxic response in animals.
