Flanking microhomology

WebJan 1, 2014 · Resection unmasks flanking microhomology, and the exposed microhomology anneals to each other in a manner independent of Rad52, the primary annealing factor in HR. The single-strand DNA-binding replication protein A (RPA) complex limits spontaneous annealing of microhomology and thereby antagonizes MMEJ. WebMicrohomology-mediated end joining (MMEJ) is an error-prone repair mechanism that involves alignment of microhomologous sequences internal to the broken ends before joining, and is associated with deletions and insertions that mark the original break site, as well as chromosome translocations.
