Compositions and methods for modifying genomic DNA sequences are provided. The methods produce double-stranded breaks (DSBs) at pre-determined target sites in a genomic DNA sequence, resulting in mutation, insertion, and/or deletion of DNA sequences at the target site(s) in a genome. 5 Compositions...

Summary: | Compositions and methods for modifying genomic DNA sequences are provided. The methods produce double-stranded breaks (DSBs) at pre-determined target sites in a genomic DNA sequence, resulting in mutation, insertion, and/or deletion of DNA sequences at the target site(s) in a genome. 5 Compositions comprise DNA constructs comprising nucleotide sequences that encode a Cpfl or Csml protein operably linked to a promoter that is operable in the cells of interest. The DNA constructs can be used to direct the modification of genomic DNA at pre-determined genomic loci. Methods to use these DNA constructs to modify genomic DNA sequences are described herein. Additionally, compositions and methods for modulating the expression of genes are provided. Compositions D comprise DNA constructs comprising a promoter that is operable in the cells of interest operably linked to nucleotide sequences that encode a mutated Cpfl or Csml protein with an abolished ability to produce DSBs, optionally linked to a domain that regulates transcriptional activity. The methods can be used to up- or down-regulate the expression of genes at predetermined genomic loci. |
