BRCA1 facilitates DNA end resection and RAD51 filament formation during homologous recombination. Zong et al. demonstrate that the RNF168-mediated chromatin ubiquitylation pathway acts redundantly with BRCA1 to promote RAD51-dependent homologous recombination. RNF168 activity is essential to prevent overt genome instability and tumorigenesis in BRCA1 heterozygous mice, independent of p53 mutation.
