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.


  • 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.

Thank you for your enquiry regarding ab3318. This antibody is a rabbit polyclonal antibody raised against the human recombinant full length proteasome 19S S5A protein. It will therefore recognise multiple epitopes on the protein. The antibody is therefore likely to contain IgGs which recognise a portion only of the protein and therefore I would expect it to recognise your truncated protein. However as this has not been tested I cannot guarantee it. I hope this information will help you in your choice of antibody,
