Abstract[English]
The present invention belongs to the field of nucleic acid editing, and particularly the technical field of clustered regularly interspaced short palindromic repeats (CRISPRs). Specifically, provided in the present invention is a Cas mutant protein having an improved activity and an improved editing efficiency. Compared with a wild-type parental Cas protein, the Cas mutant protein of the present invention has significantly improved activity, and has a wide application prospect.[French]
La présente invention appartient au domaine de l'édition des acides nucléiques, et plus particulièrement au domaine technique des courtes répétitions palindromiques groupées régulièrement espacées (CRISPR). Plus spécifiquement, la présente invention fournit une protéine mutante Cas présentant une activité améliorée et une efficacité d'édition améliorée. Comparée à une protéine Cas parentale de type sauvage, la protéine Cas mutante de la présente invention présente une activité nettement améliorée, et ses perspectives d'application sont vastes.[Chinese]
