    Abstract: The present invention relates to Transcription Activator-Like Effector (TALE) derived proteins that allow to efficiently target and/or process double stranded nucleic acid sequences. The proteins of the invention are typically chimeric protein monomers composed of a core scaffold comprising Repeat Variable Dipeptide regions (RVDs) having binding specificity to a DNA target sequence, to which is fused a catalytic domain to its N-terminal. This later catalytic domain, which can be a monomer of a nuclease, is placed at this position to possibly interact with another catalytic domain fused to another TAL monomer, such that, when said monomers are binding to their respective target DNA sequences, both catalytic domains form a catalytic entity likely to process DNA in the proximity of these target sequences. This new TAL architecture makes it possible to target only one DNA strand, which is not the case, for instance, with classical TALEN architectures. The present invention also relates to vectors encoding such proteins and compositions or kits in which Transcription Activator-Like Effector (TALE) proteins of the present invention are used.

    Abstract translation: 本发明涉及允许有效靶向和/或加工双链核酸序列的转录激活子样效应子（TALE）衍生蛋白。 本发明的蛋白质通常是由包含对DNA靶序列具有结合特异性的重复可变二肽区域（RVD）的核心支架构成的嵌合蛋白质单体，将催化结构域融合到其N-末端。 该后续的催化结构域（其可以是核酸酶的单体）置于该位置以可能与另一个与另一个TAL单体融合的另一催化结构域相互作用，使得当所述单体与其各自的靶DNA序列结合时，两个催化结构域 形成可能在这些靶序列附近处理DNA的催化实体。 这种新的TAL架构使得可以仅靶向一条DNA链，而不是例如经典的TALEN架构。 本发明还涉及编码这样的蛋白质的载体，其中使用本发明的转录激活剂样效应子（TALE）蛋白质的组合物或试剂盒。
