  • Application notes
    Is unsuitable for ICC or IHC-P.
  • Target

    • Function

      Inhibitor of the E3 ubiquitin-protein ligase ITCH. Acts by interacting with the second WW domain of ITCH, leading to compete with ITCH's substrates and impairing ubiquitination of substrates.
    • Tissue specificity

      Detected in heart, lung, brain, liver, skeletal muscle, pancreas, kidney, spleen, testis and ovary.
    • Sequence similarities

      Belongs to the N4BP1 family.
    • Post-translational

      Monoubiquitinated by NEDD4. Polyubiquitinated, leading to its degradation by the proteasome. Sumoylated by SUMO1, abrogating polyubiquitination and subsequent degradation. Desumoylated by SENP1, leading to accumulation in PML nuclear bodies.
      Phosphorylated upon DNA damage, probably by ATM or ATR.
    • Cellular localization

      Nucleus > nucleolus. Nucleus > PML body. Primarily localizes to the nucleolus. Also localizes to the PML nuclear bodies, when desumoylated.
