WB
  • 追加情報
    WB on fusion protein: 1/1000. Detects a band of approximately 60 kDa (predicted molecular weight: 58 kDa).


    This antibody has been used to successfully detect PNK as a fusion protein in a yeast lysate (see picture below). However, it has not been successfully used to detect endogenous PNK in cell lines (HepG2, HeLa and 293).

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.

  • ターゲット情報

    • 機能
      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.
    • 組織特異性
      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).
    • 関連疾患
      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.
    • 配列類似性
      In the N-terminal section; belongs to the DNA 3' phosphatase family.
    • 翻訳後修飾
      Phosphorylated upon DNA damage, probably by ATM or ATR.
    • 細胞内局在
      Nucleus.
