Flanking microhomology
WebNov 3, 2024 · The STRs in nad7-1 have a 7-bp microhomology (TAG7) flanking the repeat array. We then scanned the mitogenomes of 136 seed plants to understand the role of microhomology in the formation of STR and mitogenome evolution. A total of 13,170 STRs were identified, and almost half of them were associated with microhomologies. 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.
