reactivity :

specificity :
This item detects human Checkpoint kinase 2 (Chk2), phosphorylated at threonine 68 (Thr68). Chk2 is a serine/threonine-protein kinase which functions as a cell cycle checkpoint regulator. ATM and ATR kinases are activated in response to ionizing and ultraviolet radiation, and phsophorylate Thr68 and other sites in the amino-terminal region of Chk2, leading to Chk2 dimerisation and activation. Activated Chk2 phosphorylates and inhibits Cdc25C phosphatase, preventing the entry into mitosis, and has been shown to stabilize the tumour suppressor protein p53, leading to cell cycle arrest in G1. In addition, Chk2 can phosphorylate BRCA1, allowing BRCA1 to restore survival after DNA damage. Chk2 is a putative tumour suppressor protein, with mutations in to the Chk2 gene linked to Li-Fraumeni syndrome, a familial cancer usually associated with inherited mutations in TP53.

storage stability :
Store at 4 degree C or at -20 degree C if preferred. Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use. Shelf Life: 18 months from date of despatch.
tested application :
ELISA (EIA), Western Blot (WB)*
app notes :
Western Blot: This item detects a band of approximately 61kDa. ELISA: Minimum Dilution: 1/10000; Maximum Dilution: 1/50000. Western Blotting: Minimum Dilution: 1/200; Maximum Dilution: 1/2000; Application Note: For the detection of phosphoproteins, tyrosine phosphatase inhibitors such as 1mM Sodium Orthovanadate should be added to the sample buffer. Milk or other casein-based blocking solutions are not recommended as casein is a phosphoprotein and its use can result in high background.

ncbi summary :
In response to DNA damage and replication blocks, cell cycle progression is halted through the control of critical cell cycle regulators. The protein encoded by this gene is a cell cycle checkpoint regulator and putative tumor suppressor. It contains a forkhead-associated protein interaction domain essential for activation in response to DNA damage and is rapidly phosphorylated in response to replication blocks and DNA damage. When activated, the encoded protein is known to inhibit CDC25C phosphatase, preventing entry into mitosis, and has been shown to stabilize the tumor suppressor protein p53, leading to cell cycle arrest in G1. In addition, this protein interacts with and phosphorylates BRCA1, allowing BRCA1 to restore survival after DNA damage. Mutations in this gene have been linked with Li-Fraumeni syndrome, a highly penetrant familial cancer phenotype usually associated with inherited mutations in TP53. Also, mutations in this gene are thought to confer a predisposition to sarcomas, breast cancer, and brain tumors. This nuclear protein is a member of the CDS1 subfamily of serine/threonine protein kinases. Several transcript variants encoding different isoforms have been found for this gene.
