Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 170 kDa (predicted molecular weight: 126 kDa).Can be blocked with Human 53BP2/ASPP2 peptide (ab36003).
ICC/IF Use a concentration of 5 µg/ml.


  • FunctionRegulator that plays a central role in regulation of apoptosis and cell growth via its interactions. Regulates TP53 by enhancing the DNA binding and transactivation function of TP53 on the promoters of proapoptotic genes in vivo. Inhibits the ability of APPBP1 to conjugate NEDD8 to CUL1, and thereby decreases APPBP1 ability to induce apoptosis. Impedes cell cycle progression at G2/M. Its apoptosis-stimulating activity is inhibited by its interaction with DDX42.
  • Tissue specificityWidely expressed. Expressed in spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocyte. Reduced expression in breast carcinomas expressing a wild-type TP53 protein. Overexpressed in lung cancer cell lines.
  • Sequence similaritiesBelongs to the ASPP family.
    Contains 2 ANK repeats.
    Contains 1 SH3 domain.
  • DomainThe ankyrin repeats and the SH3 domain are required for a specific interactions with TP53.
  • Cellular localizationCytoplasm > perinuclear region. Nucleus. Predominantly found in the perinuclear region. Some small fraction is nuclear. Sequester in the cytoplasm on overexpression of DDX42.

    IRDye 680 Conjugated Goat Anti-Rabbit IgG (H+L) at 1/10000 dilution

    Performed under reducing conditions.

    Predicted band size : 126 kDa
    Observed band size : 170 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 145 kDa. We are unsure as to the identity of these extra bands.
  • ICC/IF image of ab36004 stained T47D 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 ab36004 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 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.
