Our Abpromise guarantee covers the use of ab70323 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB 1/1000 - 1/10000. Detects a band of approximately >220 kDa (predicted molecular weight: 214 kDa).
IP Use at 1-4 µg/mg of lysate.
Flow Cyt Use 0.25µg for 106 cells.

0.25 μg per 1 million cells in a 150 mcl reaction.

ab171870-Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
IHC-P 1/1000 - 1/5000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • 功能May have a role in checkpoint signaling during mitosis. Enhances TP53-mediated transcriptional activation. Plays a role in the response to DNA damage.
  • 疾病相关Note=A chromosomal aberration involving TP53BP1 is found in a form of myeloproliferative disorder chronic with eosinophilia. Translocation t(5;15)(q33;q22) with PDGFRB creating a TP53BP1-PDGFRB fusion protein.
  • 序列相似性Contains 2 BRCT domains.
  • 翻译后修饰Asymmetrically dimethylated on Arg residues by PRMT1. Methylation is required for DNA binding.
    Phosphorylated at basal level in the absence of DNA damage. Hyper-phosphorylated in an ATM-dependent manner in response to DNA damage induced by ionizing radiation. Hyper-phosphorylated in an ATR-dependent manner in response to DNA damage induced by UV irradiation.
  • 细胞定位Nucleus. Chromosome > centromere > kinetochore. Associated with kinetochores. Both nuclear and cytoplasmic in some cells. Recruited to sites of DNA damage, such as double stand breaks. Methylation of histone H4 at 'Lys-20' is required for efficient localization to double strand breaks.
