Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 48 kDa (predicted molecular weight: 37 kDa).
IP 1/10 - 1/100.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
ICC 1/100 - 1/250.
  • Application notesIs unsuitable for Flow Cyt.
  • Target

    • FunctionInhibits NF-kappa-B by complexing with and trapping it in the cytoplasm. However, the unphosphorylated form resynthesized after cell stimulation is able to bind NF-kappa-B allowing its transport to the nucleus and protecting it to further NFKBIA-dependent inactivation. Association with inhibitor kappa B-interacting NKIRAS1 and NKIRAS2 prevent its phosphorylation rendering it more resistant to degradation, explaining its slower degradation.
    • Tissue specificityExpressed in all tissues examined.
    • Sequence similaritiesBelongs to the NF-kappa-B inhibitor family.
      Contains 6 ANK repeats.
    • Post-translational
      Phosphorylated by RPS6KA1; followed by degradation. Interaction with NKIRAS1 and NKIRAS2 probably prevents phosphorylation.
    • Cellular localizationCytoplasm. Nucleus.
