    basic FUNCTION
  • functional modulator of the transcriptional activation function Wilms tumor suppressor gene (WT1)
  • required for the maturation of extramitochondrial Fe/S proteins (Srinavasan 2007)
  • apoptosome-activating protein
  • in the CIA pathway, CIAO1 cooperates with CIAO2A, CIAO2B, and MMS19 targeting factors to form various complexes that mediate the dedicated maturation of specific Fe/S recipient proteins
  • CIAO1 an essential component of the cytosolic iron-sulfur protein assembly (CIA) machinery, is crucial for Fe/S cluster insertion into RSAD2 and hence for RSAD2 antiviral activity
    • CELLULAR PROCESS protein, post translation
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • essential component of the cytosolic Fe/S protein assembly machinery
  • FAM96B-CIAO1-MMS19 complex binds to and facilitates assembly of most cytosolic-nuclear Fe/S proteins
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with WT1
  • CIAO2B and CIAO1 associate with the C terminus of MMS19 (
  • CIAO2A and CIAO2B form mutually exclusive complexes with CIAO1 to allow for selective interaction with different target Fe/S protein
