RNA-guided human genome engineering
A method of altering a eukaryotic cell is provided including transfecting the eukaryotic cell with a nucleic acid encoding RNA complementary to genomic DNA of the eukaryotic cell, transfecting the eukaryotic cell with a nucleic acid encoding an enzyme that interacts with the RNA and cleaves the genomic DNA in a site specific manner, wherein the cell expresses the RNA and the enzyme, the RNA binds to complementary genomic DNA and the enzyme cleaves the genomic DNA in a site specific manner.
1. A method of altering a eukaryotic cell comprising
providing the eukaryotic cell with a guide RNA having a spacer sequence complementary to genomic DNA of the eukaryotic cell and a scaffold sequence,
providing the eukaryotic cell with a codon optimized Cas9 that interacts with the guide RNA and cleaves the genomic DNA in a site specific manner,
wherein the guide RNA binds to complementary genomic DNA and the codon optimized Cas9 cleaves the genomic DNA in a site specific manner, and wherein the codon optimized Cas9 is a human codon optimized Cas9 encoded by a nucleic acid comprising SEQ ID NO:22.
2. The method of claim 1 wherein the eukaryotic cell is provided with the guide RNA by introducing into the eukaryotic cell a nucleic acid encoding the guide RNA and wherein the eukaryotic cell is provided with the codon optimized Cas9 by introducing into the eukaryotic cell a nucleic acid encoding the codon optimized Cas9.
3. The method of claim 1 wherein the eukaryotic cell is a yeast cell, a plant cell or a mammalian cell.
4. The method of claim 1 wherein the guide RNA includes between about 10 to about 250 nucleotides.
5. The method of claim 1 wherein the guide RNA includes between about 20 to about 100 nucleotides.

7. A method of altering a eukaryotic cell at a plurality of genomic DNA sites comprising
providing the eukaryotic cell with a plurality of guide RNAs, each guide RNA having a spacer sequence complementary to a different site on genomic DNA of the eukaryotic cell and a scaffold sequence,
providing the eukaryotic cell with a codon optimized Cas9,
wherein the guide RNAs bind to complementary genomic DNA and the codon optimized Cas9 cleaves the genomic DNA in a site specific manner, and wherein the codon optimized Cas9 is a human codon optimized Cas9 encoded by a nucleic acid comprising SEQ ID NO:22.
8. The method of claim 7 wherein the eukaryotic cell is provided with the plurality of guide RNAs by introducing into the eukaryotic cell a plurality of nucleic acids encoding the guide RNAs and wherein the eukaryotic cell is provided with the codon optimized Cas9 by introducing into the eukaryotic cell a nucleic acid encoding the codon optimized Cas9.
9. The method of claim 7 wherein the eukaryotic cell is a yeast cell, a plant cell or a mammalian cell.
10. The method of claim 7 wherein the guide RNA includes between about 10 to about 250 nucleotides.
11. The method of claim 7 wherein the guide RNA includes between about 20 to about 100 nucleotides.
