Abstract[English]
Disclosed herein include methods, compositions, and kits suitable for use in gene editing. RT editing systems are provided herein comprising a fusion protein comprising a Cas9 nickase and a reverse transcriptase, and a template armed guide RNA (tagRNA) comprising from 5' to 3' a spacer sequence, a scaffold sequence, an editing template and a flap binding sequence. In some embodiments, the RT editing system further comprises an enhancer guide RNA (egRNA).[French]
L'invention concerne des procédés, des compositions et des kits appropriés pour une utilisation dans l'édition génomique. L'invention concerne des systèmes d'édition RT comprenant une protéine de fusion comprenant une nickase Cas9 et une transcriptase inverse, et un ARN guide armé d'un modèle (ARNtag) comprenant de 5' à 3' une séquence d'espaceur, une séquence d'échafaudage, un modèle d'édition et une séquence de liaison de lambeau. Dans certains modes de réalisation, le système d'édition de RT comprend en outre un ARN guide amplificateur (ARNeg).
