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

    • Function

      Binds and presumably selects ubiquitin-conjugates for destruction. Displays selectivity for longer polyubiquitin chains. Modulates intestinal fluid secretion.
    • Sequence similarities

      Belongs to the proteasome subunit S5A family.
      Contains 2 UIM (ubiquitin-interacting motif) repeats.
      Contains 1 VWFA domain.
    • Domain

      The 2 UIM motifs are involved in the binding to a multi-ubiquitin chain in a cooperative way.
    • Post-translational

      Phosphorylated upon DNA damage, probably by ATM or ATR.
