Abstract
Methods of cleaving double-stranded DNA that can be recognized and cleaved by a rationally-designed, I-CreI-derived meganuclease are provided. Also provided are recombinant nucleic acids, cells, and organisms containing such recombinant nucleic acids, as well as cells and organisms produced using such meganucleases. Also provided are methods of conducting a custom-designed, I-CreI-derived meganuclease business.
Claims11
A method for cleaving a double-stranded DNA comprising:
- (a) identifying in said DNA at least one recognition site for a rationally-designed I-CreI-derived meganuclease with altered specificity relative to I-CreI, wherein said recognition site is not cleaved by a naturally-occurring I-CreI,
- wherein said recognition site has a four base pair central sequence selected from the group consisting of ATAC, TTGC, and GTGC;
- (b) providing said rationally-designed meganuclease;
- and
- (c) contacting said DNA with said rationally-designed meganuclease;
- whereby said rationally-designed meganuclease cleaves said DNA.
