应用 Ab评论 说明
IP 1/50.
WB 1/1000 - 1/5000. Detects a band of approximately 62 kDa (predicted molecular weight: 61 kDa).
Dot blot 1/500.
  • 应用说明Is unsuitable for Flow Cyt,ICC or IHC.
  • 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Phosphorylated by PLK4.
    • 细胞定位Nucleus; Nucleus. Isoform 10 is present throughout the cell and Nucleus > PML body. Nucleus > nucleoplasm. Recruited into PML bodies together with TP53.
