Protein: HIF1N_HUMAN

Hypoxia-inducible factor 1-alpha inhibitor

FUNCTION: 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. CATALYTIC ACTIVITY: Peptide L-aspartate + 2-oxoglutarate + O(2) = peptide 3-hydroxy-L-aspartate + succinate + CO(2). COFACTOR: Iron. more...

SUBUNIT: Homodimer. Interacts with VHL and HIF1A. Part of a complex with VHL, HIF1A and HDAC1 or HDAC2 or HDAC3.

SUBCELLULAR LOCATION: Nucleus (Potential).

SIMILARITY: Contains 1 JmjC domain.

GENE SYNONYMS: FIH1.
