    摘要: A composition is disclosed that comprises at least one protein component of an RNA-guided endonuclease (RGEN) and at least one cell-penetrating peptide (CPP), wherein the RGEN protein component and CPP are covalently or non-covalently linked to each other in an RGEN protein-CPP complex. The RGEN protein-CPP complex can traverse (i) a cell membrane, or (ii) a cell wall and cell membrane, of a cell. The RGEN protein component of an RGEN protein-CPP complex in certain embodiments can be associated with a suitable RNA component to provide an RGEN capable of specific DNA targeting. Further disclosed are compositions comprising at least one protein component of a guide polynucleotide/Cas endonuclease complex and at least one CPP, as well as methods of delivering RGEN proteins into microbial cells, as well as methods of targeting DNA with RGENs.

    摘要: Compositions and methods are provided for modifying a nucleotide sequence in the genome of a cell. The methods and compositions employ a guide polynucleotide, a protected polynucleotide modification template and a Cas endonuclease to modify a nucleotide sequence and/or to increase the frequency of homologous directed repair. The methods can further be used to decrease the frequency of off-site integration of any modification template. The present disclosure also describes methods for selecting a cell comprising a modified target site in its genome and methods for selecting a cell comprising a polynucleotide of interest inserted into a target site in its genome.
