Most proteins receive an acetyl group at the N terminus while in their nascency as the result of modification by co-translationally acting N-terminal acetyltransferases (NATs). The N-terminal acetyl group can influence several aspects of protein functionality. From studies of NAT-lacking cells, it is evident that several cellular processes are affected by this modification. More recently, an increasing number of genetic cases have demonstrated that N-terminal acetylation has crucial roles in human physiology and pathology. In this Cell Science at a Glance and the accompanying poster, we provide an overview of the human NAT enzymes and their properties, substrate coverage, cellular roles and connections to human disease.
大多数蛋白质在其初生阶段会在 N 端接受乙酰基,这是共翻译作用的 N 端乙酰转移酶 (NATs) 修饰的结果。N 端乙酰基可以影响蛋白质功能的几个方面。从缺乏 NAT 的细胞研究中可以明显看出,这种修饰会影响几个细胞过程。最近,越来越多的遗传病例表明,N 端乙酰化在人类生理学和病理学中起着至关重要的作用。在这篇《细胞科学一览》及其配套海报中,我们概述了人类 NAT 酶及其特性、底物覆盖范围、细胞作用以及与人类疾病的联系。
