成簇规则间隔短回文重复序列 (CRISPR)-CRISPR 相关蛋白的工程继续扩展可用于基因组编辑、重编程基因调控、基因组可视化和活体生物体表观遗传学研究的工具包。在这篇综述中,将介绍使用基于核酸酶缺陷的 CRISPR 的基因表达重编程的新兴设计原则。该审查将重点关注在酵母中在 CRISPR 蛋白和引导 RNA (gRNA) 水平上实施的设计,但也会对在其他相关物种中进行的开创性研究给予应有的认可。除了设计原理之外,本综述还重点介绍了受益于 CRISPR 介导的转录调控的应用,并讨论了进一步扩展核酸酶缺陷型基因组重编程工具包的未来方向。因此,这篇综述应该引起实验者普遍的兴趣,以熟悉使用核酸酶缺陷型 CRISPR 技术重编程基因组功能的能力背后的参数。 CRISPR技术可用于调节基因表达,而无需使用天然转录调节因子。
The engineering of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)-CRISPR-associated proteins continues to expand the toolkit available for genome editing, reprogramming gene regulation, genome visualisation and epigenetic studies of living organisms. In this review, the emerging design principles on the use of nuclease-deficient CRISPR-based reprogramming of gene expression will be presented. The review will focus on the designs implemented in yeast both at the level of CRISPR proteins and guide RNA (gRNA), but will lend due credits to the seminal studies performed in other species where relevant. In addition to design principles, this review also highlights applications benefitting from the use of CRISPR-mediated transcriptional regulation and discusses the future directions to further expand the toolkit for nuclease-deficient reprogramming of genomes. As such, this review should be of general interest for experimentalists to get familiarised with the parameters underlying the power of reprogramming genomic functions by use of nuclease-deficient CRISPR technologies. CRISPR technology can be used for regulating expression of genes without the use of native transcriptional regulators.
