  • Application notes
    Is unsuitable for Flow Cyt.
  • Target

    • Function

      Inhibits 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 specificity

      Expressed in all tissues examined.
    • Sequence similarities

      Belongs to the NF-kappa-B inhibitor family.
      Contains 6 ANK repeats.
    • Post-translational
      modifications

      Phosphorylated by RPS6KA1; followed by degradation. Interaction with NKIRAS1 and NKIRAS2 probably prevents phosphorylation.
    • Cellular localization

      Cytoplasm. Nucleus.

      Observed band size: 48 kDa
      why is the actual band size different from the predicted?

    • Lane 1: Wild type HAP1 whole cell lysate (20 µg)
      Lane 2: IKB beta knockout HAP1 whole cell lysate (20 µg)
      Lane 3: HeLa whole cell lysate (20 µg)

      Lanes 1 - 3: Merged signal (red and green). Green - unpurified ab109509 observed at 45 kDa. Red - loading control, ab18058, observed at 130 kDa.

      ab109509 was shown to specifically react with IKB beta in wild type cells as signal was lost in IKB beta knockout cells. Wild-type and IKB beta knockout samples were subjected to SDS-PAGE. ab109509 and ab18058 (Mouse anti-Vinculin loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
