Overview

  • Product nameAnti-Chk2 (phospho T68) antibody
    See all Chk2 primary antibodies
  • Description
    Rabbit polyclonal to Chk2 (phospho T68)
  • Specificityab3501 was tested using MCF7 cells treated with different amounts of doxorubicin (a DNA damaging agent). As the treatment increased the WB signal at 60kDa representing Chk2 increased, indicating that ab3501 was detecting the phosphorylated form of the protein. It has also been shown by peptide ELISA to be specific for the phosphorylated form of the immunizing peptide versus the non-phosphorylated form.
  • Tested applicationsSuitable for: WBmore details
  • Species reactivity
    Reacts with: Human
    Predicted to work with: Mouse, Rat, Chimpanzee
  • Immunogen

    Synthetic peptide: (C)ETVSTpQELYS, corresponding to amino acids 64-73 of Chk2.

Application Abreviews Notes
WB 1/200 - 1/2000. Detects a band of approximately 61 kDa (predicted molecular weight: 61 kDa).

Target

  • FunctionRegulates cell cycle checkpoints and apoptosis in response to DNA damage, particularly to DNA double-strand breaks. Inhibits CDC25C phosphatase by phosphorylation on 'Ser-216', preventing the entry into mitosis. May also play a role in meiosis. Regulates the TP53 tumor suppressor through phosphorylation at 'Thr-18' and 'Ser-20'.
  • Tissue specificityHigh expression is found in testis, spleen, colon and peripheral blood leukocytes. Low expression is found in other tissues.
  • Involvement in diseaseDefects in CHEK2 are associated with Li-Fraumeni syndrome 2 (LFS2) [MIM:609265]; a highly penetrant familial cancer phenotype usually associated with inherited mutations in p53/TP53.
    Defects in CHEK2 may be a cause of susceptibility to prostate cancer (PC) [MIM:176807]. It is a malignancy originating in tissues of the prostate. Most prostate cancers are adenocarcinomas that develop in the acini of the prostatic ducts. Other rare histopathologic types of prostate cancer that occur in approximately 5% of patients include small cell carcinoma, mucinous carcinoma, prostatic ductal carcinoma, transitional cell carcinoma, squamous cell carcinoma, basal cell carcinoma, adenoid cystic carcinoma (basaloid), signet-ring cell carcinoma and neuroendocrine carcinoma.
    Defects in CHEK2 are found in some patients with osteogenic sarcoma (OSRC) [MIM:259500].
  • Sequence similaritiesBelongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CHK2 subfamily.
    Contains 1 FHA domain.
    Contains 1 protein kinase domain.
  • Post-translational
    modifications
    Phosphorylated by PLK4.
  • Cellular localizationNucleus; Nucleus. Isoform 10 is present throughout the cell and Nucleus > PML body. Nucleus > nucleoplasm. Recruited into PML bodies together with TP53.
