Application Abreviews Notes
ICC/IF 1/100 - 1/250.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Predicted molecular weight: 57 kDa.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      Catalyzes 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 specificity
      Expressed 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 disease
      Defects 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 similarities
      In the N-terminal section; belongs to the DNA 3' phosphatase family.
    • Post-translational
      Phosphorylated upon DNA damage, probably by ATM or ATR.
