摘要：
The present invention relates to a method of modifying a target sequence in the genome of a eukaryotic cell, the method comprising the step: (a) introducing into the cell a fusion protein comprising a DNA-binding domain of a Tal effector protein and a non-specific cleavage domain of a restriction nuclease or a nucleic acid molecule encoding the fusion protein in expressible form, wherein the fusion protein specifically binds within the target sequence and introduces a double strand break within the target sequence. The present invention further relates to the method of the invention, wherein the modification of the target sequence is by homologous recombination with a donor nucleic acid sequence further comprising the step: (b) introducing a nucleic acid molecule into the cell, wherein the nucleic acid molecule comprises the donor nucleic acid sequence and regions homologous to the target sequence. The present invention also relates to a method of producing a non-human mammal or vertebrate carrying a modified target sequence in its genome. Furthermore, the present invention relates to a fusion protein comprising a DNA-binding domain of a Tal effector protein and a non-specific cleavage domain of a restriction nuclease.
