    特异性
    This affinity purified antibody is directed against the phosphorylated form of human CHK2 at the pT68 residue. The product was affinity purified from monospecific antiserum by immunoaffinity purification. Antiserum was first purified against the phosphorylated form of the immunizing peptide. The resultant affinity purified antibody was then cross adsorbed against the non-phosphorylated form of the immunizing peptide. Reactivity occurs against human CHK2 pT68 protein and the antibody is specific for the phosphorylated form of the protein. Reactivity with non-phosphorylated human CHK2 is minimal by ELISA. The antibody does not cross-react with Chk2 phosphorylated at other sites. A BLAST analysis was used to suggest reactivity with this protein from human and chimpanzee based on 100 % homology for the immunogen sequence. Cross reactivity with CHK2 protein from mouse and rat may occur as sequence homology varies by one amino acid residues in this sequence (90 % homology). Cross reactivity with CHK2 homologues from other sources has not been determined.
    纯化方法
    Immunoaffinity chromatography.
    免疫原
    This affinity purified antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding aa 64-73 of Human CHK2.

  • 应用备注
    Suitable for use in ELISA (1/10,000-1/50,000) and Western blot (1/200-1/2,000). Expect aband approx. 61 kDa in size corresponding to CHK2 by Western blotting in the appropriate celllysate or extract. Less than 1 % reactivity is observed against the non-phosphorylated formof the immunizing peptide.
    Other applications not tested.
    Optimal dilutions are dependent on conditions and should be determined by the user.

    背景
    CHK2 is a serine/threonine-protein kinase involved in the control of cell cycle checkpoints and may also participate in transduction of the DNA damage and replicational stress signals. CHK2 is the mammalian ortholog of the budding yeast Rad53 and fission yeast Cds1 checkpoint kinases. The amino-terminal domain of CHK2 contains a series of seven serine and threonine residues (Ser19, Thr26, Ser28, Ser33, Ser35, Ser50 and Thr68) followed by glutamine (SQ or TQ motif). These are known to be preferred sites for phosphorylation by ATM/ATR kinases. Indeed, after DNA damage by ionizing radiation (IR), UV irradiation or hydroxyurea treatment, Thr68 and other sites in this region become phosphorylated by ATM/ATR. The SQ/TQ cluster domain, therefore, seems to have a regulatory function. Phosphorylation at Thr68 is a prerequisite for the subsequent activation step, which is attributable to autophosphorylation of Chk2 on residues Thr383 and Thr387 in the activation loop of the kinase domain. CHK2 inhibits CDC25C phosphatase by phosphorylating it on Ser-216, preventing the entry into mitosis. This kinase may have a role in meiosis as well. Kinase activity is up regulated by autophosphorylation and the protein is rapidly phosphorylated in response to DNA damage and to replication block. CHK2 shows a nuclear localization and is highly expressed in testis, spleen, colon and peripheral blood leukocytes. Low levels of expression are found in other tissues. Defects in CHEK2 are associated with Li-Fraumeni syndrome (LFS), a highly penetrant familial cancer phenotype usually associated with inherited mutations in p53/TP53. Defects in CHEK2 are also found in some patients with prostate cancer (CaP) or osteosarcoma (OSRC). Substantial amino acid variants exist in some cancer tissues. Numerous truncated splice variants exist for this protein.Synonyms: CHEK-2, CHEK2, CHK-2, CHK2 checkpoint homolog, Cds1, RAD53, Serine/threonine-protein kinase Chk2
