== Publication Abstract from PubMed ==
Precise regulation of the evolutionarily conserved hypoxia-inducible transcription factor (HIF) ensures proper adaptation to variations in oxygen availability throughout development and into adulthood. Oxygen-dependent regulation of HIF stability and activity are mediated by hydroxylation of conserved proline and asparagine residues, respectively. Because the relevant prolyl and asparginyl hydroxylases use O(2) to effect these posttranslational modifications, these enzymes are implicated as direct oxygen sensors in the mammalian hypoxic response pathway. Here we present the structure of factor-inhibiting HIF-1 (FIH-1), the pertinent asparaginyl hydroxylase involved in hypoxic signaling. Hydroxylation of the C-terminal transactivation domain (CTAD) of HIF by FIH-1 prevents CTAD association with transcriptional coactivators under normoxic conditions. Consistent with other structurally known hydroxylases, FIH-1 is comprised of a beta-strand jellyroll core with both Fe(II) and the cosubstrate 2-oxoglutarate bound in the active site. Details of the molecular contacts at the active site of FIH-1 have been elucidated and provide a platform for future drug design. Furthermore, the structure reveals the presence of a FIH-1 homodimer that forms in solution and is essential for FIH activity.

Function

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.[1] [2] [3] [4] [5] [6] [7] [8]
