In some case, the cell does not naturally produce Cas protein and is genetically engineered to produce a Cas protein. As set forth elsewhere in this disclosure, a DNA-binding domain can be engineered to bind to virtually any desired sequence.
Pat. Nos. 6,453,242 and 6,794,136), one or more of the individual zinc fingers of a multi-finger binding domain can bind to overlapping quadruplet subsites. Pat. Nos. 8,586,526; 8,592,645; 8,399,218; 8,329,986; 7,888,121; 6,453,242; and 6,534,261 and U.S. See, also, U.S.
Patent Publication Nos. See, e.g., U.S. Pat. The disclosed methods and compositions include fusion proteins comprising a DNA-binding domain (e.g., ZFP, TALE, etc.) and a regulatory domain or cleavage (e.g., nuclease) domain (or a cleavage half-domain), in which the DNA-binding domain, by binding to a sequence in cellular chromatin in one or more plant genes, induces cleavage and targeted integration of one or more exogenous sequences (including transgenes) into the vicinity of the target sequence.
