Especificidade

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.

Imunogênio

recombinant human Chk2.

Aplicação

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.

Ações bioquímicas/fisiológicas

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.

forma física

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

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

CHEK2 (previously known as "CHK2") is a cell-cycle-checkpoint kinase that phosphorylates p53 and BRCA1 in response to DNA damage. A protein-truncating mutation, 1100delC in exon 10, which abolishes the kinase function of CHEK2, has been found in families with Li-Fraumeni
