| abstract |
The invention provides an improved genome editing construct which is capable of editing a target sequence in an HDR-dependent manner (i.e., “HDR-dependent genome editors”) with increased efficiency and reduced indel formation and which does not require a dividing cell. In particular, the instant specification provides a new fusion protein comprising a nucleic acid programmable DNA binding protein (napDNAbp) (e.g., Cas9) with a nickase activity and a single-stranded DNA binding protein (e.g., Rad51) which edits a target DNA in an HDR-dependent manner with greater efficiency (e.g., increased rate of induced HDR) and/or with a lower rate or occurrence of indel formation. |
