    摘要: The identification and use of two major DNA-PKcs autophosphorylation sites. Threonine (T) 2609 and Serine (S) 2056, including antibodies specific for phosphorylated T2609 and 52056. Peptides and polynucleotides encoding same, that feature these two sites of phosphorylation. The antibodies do not bind to the unphosphorylated DNA-PKcs protein or peptide, thus providing diagnostic tools to monitor the effectiveness of treatments which target the DNA repair pathway of cancer cells, and the ability to intervene or inhibit in phosphorylation of T2609 or 52056, either through application of a drug or an antibody, to increase the radiosensitivity of cancer cells.
