    See all PNK primary antibodies
  • Description
    Rabbit polyclonal to PNK
  • SpecificityThis antibody detects a band corresponding to PNK in an EM9 cell (hamster) lysate overexpressing PNK, it does not detect this band in a wildtype EM9 cell lysate. It detects a band of the same size in Hela cell lysate.

Application Abreviews Notes
WB 1/1000. Detects a band of approximately 57 kDa (predicted molecular weight: 57 kDa).


  • 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.
