共同进化军备竞赛是创新的沃土。移动遗传元件(MGEs)对其原核宿主施加的强大选择压力证明了这一点,产生了限制性内切酶和CRISPR-Cas核酸酶等强大的技术。聚集的、有规律间隔的短回文重复序列(CRISPR)和CRISPR相关基因(Cas)是原核生物适应性免疫系统的一个多样化家族,已成为一种生物技术工具和治疗方法。CRISPR-Cas系统的蛋白质抑制剂,称为“抗crispr”(Acrs)的发现,使开发更可控和精确的CRISPR-Cas工具成为可能。本文将讨论Acr蛋白在原核生物和哺乳动物细胞、生物和生态系统中用于CRISPR-Cas系统翻译后控制的应用。
Co-evolutionary arms races are fertile ground for innovation. The strong selective pressures exerted by mobile genetic elements (MGEs) on their prokaryotic hosts exemplify this, yielding robust technologies such as restriction enzymes and CRISPR-Cas nucleases. Clustered, regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) genes, a diverse family of prokaryotic adaptive immune systems, have emerged as a biotechnological tool and therapeutic. The discovery of protein inhibitors of CRISPR-Cas systems, called “anti-CRISPRs” (Acrs), enables the development of more controllable and precise CRISPR-Cas tools. The applications of Acr proteins for post-translational control of CRISPR-Cas systems in prokaryotic and mammalian cells, organisms, and ecosystems will be discussed here.
