Application Abreviews Notes
ICC/IF Use a concentration of 5 µg/ml.

IP Use at 2-5 µg/mg of lysate.


  • Function

    Regulator that plays a central role in regulation of apoptosis via its interaction with p53/TP53. Regulates TP53 by enhancing the DNA binding and transactivation function of TP53 on the promoters of proapoptotic genes in vivo.
  • Tissue specificity

    Reduced expression in breast carcinomas expressing a wild-type TP53 protein.
  • Sequence similarities

    Belongs to the ASPP family.
    Contains 2 ANK repeats.
    Contains 1 SH3 domain.
  • Domain

    The ankyrin repeats and the SH3 domain are required for specific interactions with TP53.
  • Cellular localization

    Cytoplasm. Nucleus. Predominantly cytoplasmic. Some fraction is nuclear.

    Predicted band size: 121 kDa
    Observed band size: 145 kDa
    why is the actual band size different from the predicted?

    Exposure time: 3 minutes
  • Immunoprecipitation/ Western Blot of ASPP1.
    Lane 1: ab71163 at 3µg/mg whole cell lysate.
    Lane 2: Control IgG.
    All lanes: Whole cell lysate from Hela cells at 1mg for IP, 20% of IP loaded.

  • ICC/IF image of ab71163 stained HepG2 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab71163, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h.Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
