Recognition of DNA double-strand breaks during non-homologous end joining is carried out by the Ku70-Ku80 protein, a 150 kDa heterodimer that recruits the DNA repair kinase DNA-dependent protein kinase catalytic subunit (DNA-PKcs) to the lesion. The atomic structure of a truncated Ku70-Ku80 was determined; however, the subunit-specific carboxy-terminal domain of Ku80--essential for binding to DNA-PKcs--was determined only in isolation, and the C-terminal domain of Ku70 was not resolved in its DN ...[more]
