靶标

  • 功能
    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'.
  • 组织特异性
    High expression is found in testis, spleen, colon and peripheral blood leukocytes. Low expression is found in other tissues.
  • 疾病相关
    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].
  • 序列相似性
    Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CHK2 subfamily.
    Contains 1 FHA domain.
    Contains 1 protein kinase domain.
  • 翻译后修饰

  • HeLa (human epithelial cell line from cervix adenocarcinoma) cells stained for Chk2 (phospho T383) (green) using ab59408 at 1/100 dilution in ICC/IF, in the presence (right panel) or absence (left panel) of immunizing phosphopetide.

  • ab59408 staining Chk2 (phospho T383) in human colon carcinoma cells by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.5% Triton X-100 and blocked with 1% BSA for 30 minutes at 37°C. Samples were incubated with primary antibody (1/100 in PBS + 1% BSA) for 1 hour at 37°C. A FITC-conjugated goat anti-rabbit IgG polyclonal (1/100) was used as the secondary antibody.
