    • The present invention relates to methods of detecting and regulating cellular DNA damage as well as methods of screening compounds suitable for modulating cellular DNA damage. The methods of the present invention utilize antibodies that selectively bind to a phosphorylated tyrosine residue in a SQEY tyrosine phosphorylation motif sequence or a phosphorylated serine residue in a KENSSQ phosphorylation motif sequence, where the phosphorylated serine residue is closest to the glutamine residue. Also encompassed by the present invention are methods of treating a subject having cancer. These methods involve the administration of an agent that modulates the phosphorylation of the tyrosine residue in a SQEY motif. Suitable agents for modulating the phosphorylation of the tyrosine residue of the SQEY motif are also disclosed.
    • 本发明涉及检测和调节细胞DNA损伤的方法以及筛选适于调节细胞DNA损伤的化合物的方法。 本发明的方法利用选择性结合SQEY酪氨酸磷酸化基序序列中的磷酸化酪氨酸残基或KENSSQ磷酸化基序序列中的磷酸化丝氨酸残基的抗体,其中磷酸化丝氨酸残基最接近谷氨酰胺残基。 本发明还包括治疗患有癌症的受试者的方法。 这些方法涉及施用调节SQEY基序中酪氨酸残基的磷酸化的试剂。 还公开了用于调节SQEY基元的酪氨酸残基磷酸化的合适试剂。
