Принадлежит:

The invention provides a Cas12a variant and an application of the Cas12a variant in gene editing, the Cas12a variant is LbCas12a-K538R, and the amino acid sequence of the Cas12a variant is shown as SED ID NO.2. The invention further provides a gene editing method of the Cas12a variant. The Cas12a variant is obtained through protein modification for the first time, PAM recognition of Cas12a is more strict than that of a corresponding wild type, and therefore the off-target effect is reduced; the three Cas12a variants can perform gene editing on eukaryotic genomes at fixed points under the mediation of crRNA and have a lower off-target effect, and the discovery of the three Cas12a variants further expands the variety of gene editing tools.
