特異性
The epitope recognized by the antibody resides within the FHA domain of the Chk2 molecule. This epitope is likely to be masked by protein-protein interactions in vivo.
免疫原
recombinant human Chk2.
應用
Suitable for immunohistochemistry (formalin-fixed, paraffin-embedded sections) and for immunoblotting at a concentration of 2 to 4 μg/mL using whole extract of cultured 293T cells.
生化／生理作用
The protein propagates signals from damaged or unreplicated DNA. The protein is expressed throughout the cell cycle. Upon activation it phosphorylates and inhibits CDC25C, which leads to increased inhibitory tyrosine phosphorylation of CDK-cyclin complexes, blocking cell cycle progression. It also regulates apoptosis through the phosphorylation of p53, a tumor suppressor protein. The protein regulates DNA repair through phosphorylation of BRCA2. Mutations in this gene have been linked to Li-Fraumeni syndrome, sarcomas, breast cancer, and brain tumors.

The association between the CHEK2 and breast cancer risk in Chinese women is unknown. Here, we screened the full CHEK2 coding sequence in 118 Chinese familial breast cancer cases who are negative for mutations in BRCA1 and BRCA2, one recurrent

The p53 protein is kept labile under normal conditions. This regulation is governed largely by its major negative regulator, Mdm2. In response to stress however, p53 accumulates and becomes activated. For this to occur, the inhibitory effects of Mdm2 have

Checkpoints maintain the order and fidelity of the eukaryotic cell cycle, and defects in checkpoints contribute to genetic instability and cancer. Much of our current understanding of checkpoints comes from genetic studies conducted in yeast. In the fission yeast Schizosaccharomyces

The DNA damage checkpoint kinase, CHK2, promotes growth arrest or apoptosis through phosphorylating targets such as Cdc25A, Cdc25C, BRCA1, and p53. Both germline and somatic loss-of-function CHEK2 mutations occur in human tumours, the former linked to the Li-Fraumeni syndrome, and

Cyclin-dependent kinase two (Cdk2) is the major regulator of the G1/S transition and the target of an activated G1 checkpoint in somatic cells. In the presence of DNA damage, Cdk2 kinase activity is abrogated by a deficiency of Cdc25A phosphatase
