Abstract:

Targeted DNA double-strand breaks introduced by rare-cleaving designer endonucleases can be harnessed for gene disruption applications by engaging mutagenic nonhomologous end-joining DNA repair pathways. However, endonuclease-mediated DNA breaks are often subject to precise repair, which limits the efficiency of targeted genome editing. To address this issue, we coupled designer endonucleases to DNA end-processing enzymes to drive mutagenic break resolution, achieving up to 25-fold enhancements in gene disruption rates.
