背景信息

The Ku-7 (Phospho-Ser5) antibody is a specialized tool used to detect the phosphorylation status of a conserved serine residue at position 5 (Ser5) within the Ku protein complex, which plays a critical role in DNA repair and genomic stability. The Ku heterodimer, composed of Ku70 and Ku80 subunits, is central to non-homologous end joining (NHEJ), the primary pathway for repairing DNA double-strand breaks (DSBs). Post-translational modifications, including phosphorylation, regulate Ku's functions in DNA damage response and repair. Phosphorylation at Ser5. specifically on the Ku80 subunit, has been implicated in modulating Ku’s DNA-binding affinity and its interaction with repair machinery components like DNA-PKcs during DSB repair. This antibody enables researchers to study the activation and regulatory mechanisms of the Ku complex under conditions such as ionizing radiation, chemotherapeutic stress, or other genotoxic insults. Validated in applications like Western blotting and immunofluorescence, it helps assess Ku80 phosphorylation dynamics in cellular models of cancer, aging, and diseases linked to DNA repair deficiencies. Specificity is confirmed using phosphorylation-deficient mutants or phosphatase-treated lysates. Insights from studies using this antibody contribute to understanding how Ku activity is tuned in pathological contexts, including tumor resistance to therapy, and may guide therapeutic strategies targeting DNA repair pathways.
