Associations of HIF1AN with chemical compounds

 

Physical interactions of HIF1AN

  • The structural core of FIH-1 consists of a jellyroll-like beta-barrel containing the conserved ferrous-binding triad residues, confirming that FIH-1 is a member of the 2-oxoglutarate-dependent dioxygenase family [13].
  • Siah-1 was found both to interact with the JmjC domain of FIH through its substrate-binding domain and to specifically ubiquitinate FIH via its RING finger domain [14].
 

Enzymatic interactions of HIF1AN

 

Other interactions of HIF1AN

  • Structure of human FIH-1 reveals a unique active site pocket and interaction sites for HIF-1 and von Hippel-Lindau [13].
  • Except for the core structure and triad residues, FIH-1 has many structural deviations from other family members including N- and C-terminal insertions and various deletions in the middle of the structure [13].
  • Sequence analyses involving FIH link the 2-OG oxygenases with members of the cupin superfamily, including Zn(II)-utilizing phosphomannose isomerase, revealing structural and evolutionary links between these metal-binding proteins that share common motifs [8].
  • Recent biochemical and candidate gene approach studies have led to the discovery of three HIF-regulatory prolyl hydroxylases, PHD-1, -2 and -3 and an asparaginyl hydroxylase, also known as FIH (factor inhibiting HIF) [16].
  • Furthermore, the asparagine hydroxylase FIH-1 (factor inhibiting HIF) has been found to hydroxylate Asp803 of the HIF-1 C-terminal transactivation domain, which results in the decreased ability of HIF-1 to bind to the transcriptional coactivator p300/CBP [17].
