DNA-PK promotes DNA end resection at DNA double strand breaks in G0 cells
9 May 2022
Abstract excerpt
DNA double-strand break (DSB) repair by homologous recombination is confined to the S and G 2 phases of the cell cycle partly due to 53BP1 antagonizing DNA end resection in G 1 phase and non-cycling quiescent (G 0 ) cells where DSBs are predominately repaired by non-homologous end joining (NHEJ). Unexpectedly, we uncovered extensive MRE11- and CtIP-dependent DNA end resection at DSBs in G 0 murine and human...
