摘要
Microhomology-mediated end joining (MMEJ) is a mechanism of DNA double-strand-break repair that creates deletions and promotes other types of genome instability. New in vivo and in vitro analyses demonstrate that the heterotrimeric replication protein A (RPA) complex prevents spontaneous annealing of microhomologies, thereby preventing genome-destabilizing MMEJ.
