基因组编辑已经通过CRISPR系统的开发得到利用,来自普雷沃氏菌和弗朗西斯氏菌1(Cpf 1)系统的CRISPR已经成为CRISPR-Cas9在各种情况下使用的有希望的替代品。尽管Cpf 1相对于Cas9具有固有的多重优势,但由于靶依赖性indel效率不足,Cpf 1的采用一直不令人满意。在这里,我们报告了一种通过Cpf 1进行高效基因组编辑的工程化CRISPR RNA(crRNA),其包括20个碱基的靶互补序列和富含尿苷酸的3′-突出端。当crRNA转录产生时,具有20个碱基的靶互补序列加上U4 AU 4 3′-突出端的crRNA是最佳构型。富含U的crRNA还最大化了AsCpf 1突变体的效用,并使用mRNA作为多种crRNA的来源进行多重基因组编辑。此外,富含U的crRNA能够在人类细胞中使用Cpf 1进行高度安全和特异性的基因组编辑,有助于增强基因组编辑工具箱。Cpf 1是Cas9的一种有前景的替代方案,尽管插入缺失产生效率是靶依赖性的。在这里,作者表明,添加polyU 3′突出端可以提高低效向导RNA的效率。
Genome editing has been harnessed through the development of CRISPR system, and the CRISPR from Prevotella and Francisella 1 (Cpf1) system has emerged as a promising alternative to CRISPR-Cas9 for use in various circumstances. Despite the inherent multiple advantages of Cpf1 over Cas9, the adoption of Cpf1 has been unsatisfactory because of target-dependent insufficient indel efficiencies. Here, we report an engineered CRISPR RNA (crRNA) for highly efficient genome editing by Cpf1, which includes a 20-base target-complementary sequence and a uridinylate-rich 3′-overhang. When the crRNA is transcriptionally produced, crRNA with a 20-base target-complementary sequence plus a U4AU4 3′-overhang is the optimal configuration. U-rich crRNA also maximizes the utility of the AsCpf1 mutants and multiplexing genome editing using mRNA as the source of multiple crRNAs. Furthermore, U-rich crRNA enables a highly safe and specific genome editing using Cpf1 in human cells, contributing to the enhancement of a genome-editing toolbox. Cpf1 is a promising alternative to Cas9 though indel generation efficiency is target dependent. Here the authors show that the addition of a polyU 3′ overhang can improve the efficiency of low efficiency guide RNAs.
