哺乳动物受精卵介导的基因组工程通过重复的规则间隔短回文重复序列(CRISPR)/Cas目前用于产生基因组修饰的动物。在这里,我们报告了空肠弯曲杆菌来源的orthopedic CRISPR/Cas系统识别5′-NNNVRYAC序列作为小鼠受精卵中的原型间隔区邻近基序,并且适用于有效产生敲除小鼠。此外,这种新的CRISPR/Cas可以用于在独特的基因座处进行合子介导的敲入,这表明该系统可以帮助扩大合子介导的基因组修饰动物的产生的可行性。
Mammalian zygote-mediated genome-engineering by Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR)/Cas is currently used for the generation of genome-modified animals. Here, we report that a Campylobacter jejuni-derived orthologous CRISPR/Cas system recognizes a 5′-NNNVRYAC sequence as a protospacer-adjacent motif in mouse zygotes, and is applicable for efficient generation of knockout mice. Moreover, this novel CRISPR/Cas can be used for zygote-mediated knock-in at a unique locus, suggesting that this system could help to expand the feasibility of the zygote-mediated generation of genome-modified animals.
