Background: 53BP1 counteracts BRCA1 in DNA repair. Results: RIF1 acts downstream of 53BP1 and counteracts BRCA1 in DNA end resection. It also has a 53BP1-independent role in regulating BLM chromatin association. Conclusion: RIF1 is the major downstream effector of 53BP1. Significance: These results reveal that RIF1 antagonizes BRCA1, functions in DNA end protection, and prevents homologous recombination repair.
