Application Abreviews Notes
WB 1/500. Detects a band of approximately 50 kDa (predicted molecular weight: 40 kDa).

By Western blot, this antibody detects a 50 kDa protein representing proteasome 19S subunit S5A in HeLa cell lysate.

IP Use at an assay dependent concentration.


  • FunctionBinds and presumably selects ubiquitin-conjugates for destruction. Displays selectivity for longer polyubiquitin chains. Modulates intestinal fluid secretion.
  • Sequence similaritiesBelongs to the proteasome subunit S5A family.
    Contains 2 UIM (ubiquitin-interacting motif) repeats.
    Contains 1 VWFA domain.
  • DomainThe 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.
