Anti ATM monoclonal Antibody was used to show constitutive activation of the ATM pathway in human urinary bladder cancer.  Anti-ATM Protein Kinase pS1981 (clone # 7C10D8 ) was used to stain normal uroepithelium, early superficial lesions (Ta), and earliest invasive (T1) primary carcinomas. ATM protein is ubiquitously expressed, but Ser 1981-phosphorylated ATM (pS-ATM) is detectable only in tumor tissues.  See Bartkova et al. for additional details.

ATM pS1981 Antibody Description

Background
Anti ATM pS1981 Antibody recognizes the product of the ATM gene that is mutated in the hereditary disease ataxia-telangiectasia. ATM codes for a protein kinase that acts as a master regulator of cellular responses to DNA double-strand breaks. ATM is normally inactive and the question of how it is activated in the event of DNA damage (due to ionizing radiation for instance) is central to understanding its function. ATM protein is now shown to be present in undamaged cells as an inactive dimer. Low doses of ionizing radiation, which induce only a few DNA breaks, activate at least half of the total ATM protein present, possibly in response to changes in chromatin structure.  The ATM gene encodes a 370-kDa protein that belongs to the phosphoinositide 3-kinase (PI(3)K) superfamily, but which phosphorylates proteins rather than lipids. The 350-amino-acid kinase domain at the carboxy terminus of this large protein is the only segment of ATM with an assigned function. Exposure of cells to IR triggers ATM kinase activity, and this function is required for arrests in G1, S and G2 phases of the cell cycle. Several substrates of the ATM kinase participate in these IR-induced cell-cycle arrests. These include p53, Mdm2 and Chk2 in the G1 checkpoint; Nbs1, Brca1, FancD2 and SMC1 in the transient IR-induced S-phase arrest; and Brca1 and hRad17 in the G2/M checkpoint. See Bakkenist, C. J. & Kastan, M. B. Nature 421, 499-506 (2003) for a complete presentation of this antibody's specificity and utility.
Immunogen
This antibody was produced from a synthetic peptide S-L-A-F-E-E-G-Sp-Q-S-T-T-I-S-S corresponding to aa 1974-1988 of human ATM.
Immunogen Type
Peptide
Post Translational Modification
Phosphorylation
Storage Condition
Store vial at -20° C prior to opening. Aliquot contents and freeze at -20° C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
Application Note
This Anti-ATM Protein Kinase pS1981 (MOUSE) Monoclonal Antibody clone has been optimized for IHC, but may also be used for western blotting, flow cytometry, immunoprecipitation, or immunofluorescence microscopy. Indirect immunoperoxidase staining on formaldehyde-fixed, de-paraffinized tissue sections and/or formalin-fixed cultured cells are recommended when using this antibody as described in Bartkova et al 2005.  Product p/n 200-301-400 produced from clone 10H11.E12 has been optimized for WB, IP and IF.
Purity/Specifity
This Protein A Purified Mab antibody is directed against human ATM and is useful in determining its presence by immunohistochemistry. This monoclonal anti-ATM antibody recognizes the phosphorylated form of the protein in native and over-expressed proteins found in various tissues and extracts.  Reactivity is observed against human and mouse ATM.  Cross reactivity with ATM from other mammalian sources has not been tested.
