abstract::Non-homologous end joining (NHEJ), the major pathway of double-strand break (DSB) repair in mammalian cells, comprises two subpathways: one that requires the three core factors Ku70/80, DNA-PKcs and XRCC4/LigIV (DNA-PK-dependent NHEJ) and the other that is independent of these factors. Using a cell-free NHEJ assay, we...
