ターゲット情報

  • 機能
    Regulates 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'.
  • 組織特異性
    High expression is found in testis, spleen, colon and peripheral blood leukocytes. Low expression is found in other tissues.
  • 関連疾患
    Defects 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].

  • ab47433 (1/200) detecting Chk2 in HeLa cells in conjunction with a goat anti-mouse secondary antibody conjugated to Cy3 (red). Cells were counterstained with DAPI in order to highlight the nucleus (blue), treated with Bleomycin and incubated with an antibody against Histone H2AX in order to create and expose DNA double strand breaks (green). Please refer to abreviews for further details.
