靶标

  • 相关性ASPP proteins (ASPP1, ASPP2 and iASPP) represent a new family of p53 binding proteins. ASPP1 and ASPP2 bind and enhance p53-mediated apoptosis. In contrast, the third member, iASPP, functionally inactivates p53. iASPP (also called protein phosphatase 1 regulatory (inhibitor) subunit 13 like protein, Inhibitor of ASPP protein, Protein iASPP, PPP1R13B-like protein and NFkB-interacting protein 1) plays a central role in regulation of apoptosis and transcription via its interaction with NF-kappa-B and p53/TP53 proteins. iASPP blocks transcription of HIV-1 virus by inhibiting the action of both NF-kappa-B and SP1. This protein also inhibits p53/TP53 function, possibly by preventing the association between p53/TP53 and ASPP1 or ASPP2, and therefore suppressing the subsequent activation of apoptosis. iASPP is predominantly a cytoplasmic protein (isoform 1) but can also be found in the nucleus (isoform 2). iASPP is highly expressed in heart, placenta and prostate and is weakly expressed in brain, liver, skeletal muscle, testis and peripheral blood leukocyte. The N-terminal region of isoform 1 is required for cytoplasmic localization. Defects in iASPP may be a cause of certain breast cancers and the protein is overexpressed in many patients suffering from breast carcinomas and expressing a wild-type p53/TP53 protein.

  • Immunoprecipitation analysis of Human HeLa whole cell lysates. The cells were immunoprecipitated untreated with a Protein A matrix diluted at 4 µg/mg lysate incubated for 2 hours at 4°C in RIPA buffer.

  • Anti-iASPP antibody (ab34898) at 1/1500 dilution (at 4°C, o/n) + 35ug of MCF7 whole cell lysate

    Secondary
    IRDye™800 conjugated anti-Rabbit IgG diluted 1:10000, for 45 min at RT

    Predicted band size : 90 kDa
    Observed band size : 102 kDa (why is the actual band size different from the predicted?)
  • IHC image of ab34898 staining in human breast carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab34898, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Unfortunately we cannot provide the iASPP peptide used as an immunizing peptide. I have found a link to the iASPP EST profile on Unigene that may help you select a negative control.
