In mammals, the majority of DNA double-strand breaks are processed by the Non Homologous End-Joining pathway (NHEJ), composed of seven factors: Ku70, Ku80, DNA-PKcs, Artemis, Xrcc4 (X4), DNA Ligase IV (L4) and Cernunnos/XLF. Cernunnos is part of the ligation complex, constituted by X4 and L4. In order to improve our knowledge on the structure...

DNA double-strand break (DSB) repair is initiated by DNA end resection. CtIP acts in short-range resection to stimulate MRE11–RAD50–NBS1 (MRN) to endonucleolytically cleave 5′-terminatedDNAto bypass protein blocks. CtIP also promotes the DNA2 helicase–nuclease to accelerate long-range resection downstream from MRN. Here, using AlphaFold2, we...
