Description

General description

The protein encoded by this gene is a serine/threonine-protein kinase that acts as a cell cycle checkpoint regulator and a putative tumor suppressor. It contains a C-terminal kinase domain, an N-terminal regulatory region that is rich in TQ and SQ pairs, and a forked head-associated domain (FHA), which is activated by rapid phosphorylation in response to replication blocks and DNA damage.

Immunogen

recombinant human Chk2.

Application

Monoclonal Anti-Chk2 antibody produced in mouse is suitable for immunocytochemistry, immunohistochemistry (formalin-fixed, paraffin-embedded sections), microarray, immunoprecipitation and for immunoblotting at a concentration of 1-2 μg/mL using whole extract of cultured 293T cells. It was used for Chk2 immunoprecipitation experiments to study the engagement of the ATR-dependent DNA damage response at the human papillomavirus 18 replication centers during the initial amplification

Biochem/physiol Actions

The epitope recognized by the antibody resides within the N-terminal regulatory domain of the Chk2 molecule.

The protein propagates signals from damaged or unreplicated DNA. It 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.

Physical form
