Single-stranded oligodeoxyribonucleotide (ssODN)-mediated repair of CRISPR/Cas9-induced DNA double-strand breaks (DSB) can effectively be used to introduce small genomic alterations in a defined locus. Here, we reveal DNA mismatch repair (MMR) activity is crucial for efficient nucleotide substitution distal from the Cas9-induced DNA break when the substitution is instructed by the 3′ half of the ssODN. Furthermore, protecting the ssODN 3′ end with phosphorothioate linkages enhances MMR-dependent gene editing events. Our findings can be exploited to optimize efficiencies of nucleotide substitutions distal from the DSB and imply that oligonucleotide-mediated gene editing is effectuated by templated break repair.
