Our Abpromise guarantee covers the use of ab70739 in the following tested applications.

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

Application Abreviews Notes
IHC-P 1/500 - 1/2000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/2500 - 1/10000. Detects a band of approximately 62 kDa (predicted molecular weight: 57 kDa).
  • Application notesIs unsuitable for IP.
  • Target

    • FunctionCatalyzes the phosphorylation of DNA at 5'-hydroxyl termini and can dephosphorylate its 3'-phosphate termini. Plays an important function in DNA repair following ionizing radiation or oxidative damage.
    • Tissue specificityExpressed in many tissues with highest expression in spleen and testis, and lowest expression in small intestine (PubMed:10446192). Expressed in higher amount in pancreas, heart and kidney and at lower levels in brain, lung and liver (PubMed:10446193).
    • Involvement in diseaseDefects in PNKP are the cause of microcephaly seizures and development delay (MCSZ) [MIM:613402]. It is characterized by microcephaly, infantile-onset seizures, severe intellectual disability and delayed motor milestones with absent speech or only achieving a few words. Most patients also have behavioral problems with hyperactivity. Microcephaly is progressive and without neuronal migration or structural abnormalities, consistent with primary microcephaly.
    • Sequence similaritiesIn the N-terminal section; belongs to the DNA 3' phosphatase family.
    • Post-translational
      Phosphorylated upon DNA damage, probably by ATM or ATR.
    • Cellular localizationNucleus.
