DNA-PK comprises Ku70/Ku80 heterodimer and the kinase subunit DNA-PKcs (p460). Here, by monitoring protein assembly from human nuclear cell extracts on DNA ends in vitro, we report that recruitment to DNA ends of the XRCC4-ligase IV complex responsible for the key ligation step is strictly dependent on the assembly of both the Ku and p460 components of DNA-PK to these ends. Based on co-immunoprecipitation experiments, we conclude that interactions of Ku and p460 with components of the XRCC4-ligase IV complex are mainly DNA-dependent. In addition, under p460 kinase permissive conditions, XRCC4 is detected at DNA ends in a phosphorylated form. This phosphorylation is DNA-PK-dependent. However, phosphorylation is dispensable for XRCC4-ligase IV loading to DNA ends since stable DNA-PK/XRCC4-ligase IV/DNA complexes are recovered in the presence of the kinase inhibitor wortmannin. These findings extend the current knowledge of the assembly of NHEJ repair proteins on DNA termini and substantiate the hypothesis of a scaffolding role of DNA-PK towards other components of the NHEJ DNA repair process."xsd:string |
