Flanking microhomology
WebNov 8, 2012 · Proposed mechanism for repair of a DSB using microhomology. After a break, ends are resected to single-stranded DNA, and microhomology flanking the break (shown in black boxes) are brought together and annealed. Rad52 facilitates repair using microhomology that is 15 bp or longer, and microhomology less than 15 bp is … WebApr 14, 2024 · Here we show microhomologies are identified by a scanning mechanism initiated from the 3' terminus and favoring bidirectional progression into flanking DNA, typically to a maximum of 15 nucleotides into each flank. Polymerase theta is frequently insufficiently processive to complete repair of breaks in microhomology-poor, AT-rich …
