Description

Immunogen

recombinant human Chk2.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% BSA and 15 mM sodium azide.

Specificity

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.

Application

Monoclonal Anti-Chk2 antibody produced in mouse is 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.

Biochem/physiol Actions

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.
