Western blot analysis of extracts from various cell lines using Chk1 (2G1D5) Mouse mAb. Western Blotting
Western blot analysis of extracts from HeLa cells, transfected with 100 nM SignalSilence® Control siRNA (Fluorescein Conjugate) #6201 (-) or SignalSilence® Chk1 siRNA I #6241 or SignalSilence® Chk1 siRNA II (+), using Chk1 (2G1D5) Mouse mAb #2360 and β-Actin (13E5) Rabbit mAb #4970. Chk1 (2G1D5) Mouse mAb confirms silencing of Chk1 expression and β-Actin (13E5) Rabbit mAb is used to control for loading and specificity of Chk1 siRNA. |
| Background | Chk1 kinase acts downstream of ATM/ATR kinase and plays an important role in DNA damage checkpoint control, embryonic development, and tumor suppression (1). Activation of Chk1 involves phosphorylation at Ser317 and Ser345 and occurs in response to blocked DNA replication and certain forms of genotoxic stress (2). While phosphorylation at Ser345 serves to localize Chk1 to the nucleus following checkpoint activation (3), phosphorylation at Ser317 along with site-specific phosphorylation of PTEN allows for reentry into the cell cycle following stalled DNA replication (4). Chk1 exerts its checkpoint mechanism on the cell cycle, in part, by regulating the cdc25 family of phosphatases. Chk1 phosphorylation of cdc25A targets it for proteolysis and inhibits its activity through 14-3-3 binding (5). Activated Chk1 can inactivate cdc25C via phosphorylation at Ser216, blocking the activation of cdc2 and transition into mitosis (6). Centrosomal Chk1 has been shown to phosphorylate cdc25B and inhibit its activation of CDK1-cyclin B1, thereby abrogating mitotic spindle formation and chromatin condensation (7). Furthermore, Chk1 plays a role in spindle checkpoint function through regulation of Aurora B and BubR1 (8). Chk1 has emerged as a drug target for cancer therapy as its inhibition leads to cell death in many cancer cell lines (9).
