  • 功能
    Binds and presumably selects ubiquitin-conjugates for destruction. Displays selectivity for longer polyubiquitin chains. Modulates intestinal fluid secretion.
  • 序列相似性
    Belongs to the proteasome subunit S5A family.
    Contains 2 UIM (ubiquitin-interacting motif) repeats.
    Contains 1 VWFA domain.
  • 结构域
    The 2 UIM motifs are involved in the binding to a multi-ubiquitin chain in a cooperative way.
  • 翻译后修饰
    Phosphorylated upon DNA damage, probably by ATM or ATR.

  • Proteasome 19S S5A was immunoprecipitated using 0.5mg Hela whole cell extract, 5µg of Mouse monoclonal to Proteasome 19S S5A and 50µl of protein G magnetic beads (+). No antibody was added to the control (-).

    The antibody was incubated under agitation with Protein G beads for 10min, Hela whole cell extract lysate diluted in RIPA buffer was added to each sample and incubated for a further 10min under agitation.

    Proteins were eluted by addition of 40µl SDS loading buffer and incubated for 10min at 70°C; 10µl of each sample was separated on a SDS PAGE gel, transferred to a nitrocellulose membrane, blocked with 5% BSA and probed with ab20239.

    Secondary: Goat polyclonal to mouse IgG light chain specific (HRP) at 1/20,000 dilution.

    Band: 41kDa; Proteasome 19S S5A

  • ab20239 (1/200) staining Proteasome 19S S5A in Human retinal pigment epithelial (RPE) cells (green). Cells were fixed in Paraformaldehyde, permeabilised with 0.5% Triton X100/PBS and counterstained with DAPI in order to highlight the nucleus (blue). Please refer to Abreview for further details.

  • Overlay histogram showing HeLa cells stained with ab20239 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab20239, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
