可以通过AAV递送用于体内基因组编辑的紧凑型CRISPR/Cas9系统对于临床应用具有很大的希望。侧孢短芽孢杆菌Cas9(BlatCas 9)是一种紧凑的Cas9核酸酶,已被鉴定用于植物基因组编辑。在这里,我们将BlatCas 9描述为哺乳动物基因组编辑的替代工具。我们证明了BlatCas 9偏好N4 CNAA原型间隔区邻近基序(PAM),但N4 C PAM在哺乳动物细胞中也是可编辑的。我们接下来证明了BlatCas 9能够在多种细胞类型中进行基因组编辑。此外,BlatCas 9可以包装到AAV中用于基因组编辑。最后,我们描述了BlatCas 9的特异性。总之,BlatCas 9为基础研究和临床应用提供了一种替代工具。
Compact CRISPR/Cas9 systems that can be delivered by AAV for in vivo genome editing hold great promise for clinical applications. Brevibacillus laterosporus Cas9 (BlatCas9) is a compact Cas9 nuclease that has been identified for plant genome editing. Here, we characterize BlatCas9 as an alternative tool for mammalian genome editing. We demonstrate that BlatCas9 prefers a N4CNAA protospacer adjacent motif (PAM), but N4C PAM is also editable in mammalian cells. We next demonstrate that BlatCas9 enables genome editing in a variety of cell types. Furthermore, BlatCas9 can be packaged into AAV for genome editing. Finally, we characterize the specificity of BlatCas9. In summary, BlatCas9 offers an alternative tool for both basic research and clinical applications.
