一般描述
Checkpoint kinase 1 (Chk1) protein is a serine/threonine-protein kinase with a molar mass of 54 kDa. Monoclonal Anti-Chk1 (mouse IgG2b isotype) is derived from the DCS-310 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from a BALB/c mouse immunized with a recombinant human Chk1.
免疫原
recombinant human Chk1.
应用
Monoclonal Anti-Chk1 antibody produced in mouse is suitable for immunohistochemistry (formalin-fixed, paraffin-embedded sections), immunoprecipitation, microarray and western blot at a working concentration of 1-2 μg/mL using whole extract of cultured 293T (human embryonal kidney) cells. It was used for immunohistochemistry in a study to investigate the specific role of Chk1 phosphorylations in cell survival and checkpoint activation. It was used for immunohistochemistry at a working dilution of 1:4000 in a study to explore Chk1 knockdown as a novel therapeutic approach to arrest cell-cycle progression in MM cells, thus increasing the rate of cell death. It was used for the immunoprecipitation and detection of total Chk1 by western blot to study a possible regulatory relationship between Chk1 and CK1, a member of the casein kinase 1 family.
Monoclonal Anti-Chk1 antibody produced in mouse has been used in:
生化/生理作用
Checkpoint kinase 1 (Chk1) protein acts as a cell cycle checkpoint regulator.
The protein propagates signals from damaged or unreplicated DNA. It is expressed and active only in S-G2 phases of the cell cycle. In response to DNA damage, it phosphorylates CDC25C at Ser 216, thus preventing activation of the Cdc2-cyclin B complex and mitotic entry, blocking cell cycle progression. This protein acts to integrate signals from ATM and ATR, two cell cycle proteins involved in DNA damage responses, that also associate with chromatin in meiotic prophase I. Chk1 can phosphorylate Wee1, a negative regulator of G2 to M transition.
