Abstract
The present invention refers to methods for selectively recognizing a base pair in a DNA sequence by a polypeptide, to modified polypeptides which specifically recognize one or more base pairs in a DNA sequence and, to DNA which is modified so that it can be specifically recognized by a polypeptide and to uses of the polypeptide and DNA in specific DNA targeting as well as to methods of modulating expression of target genes in a cell.
Claims3
A non-human animal cell or in vitro human cell comprising a fusion protein, the fusion protein comprising an artificial transcription activator-like (TAL) effector repeat domain of contiguous repeat units 33 to 35 amino acids in length and an endonuclease domain, wherein the repeat domain is engineered for recognition of a predetermined nucleotide sequence in the non-human animal cell or in vitro human cell, and wherein the fusion protein is capable of recognizing the predetermined nucleotide sequence in the non-human animal cell or in vitro human cell.
