Collisions of transcription and replication machineries on the same DNA strand threaten genomic stability. Here, the authors show that RAD52 prevents these collisions by regulating R-loop formation and resolution. RAD52 deficiency leads to increased R-loops, exacerbated collisions, DNA damage, and higher mutational burden in tumors.
