Abstract

The small ubiquitin-like modifier (SUMO) is a ubiquitin-like protein that covalently modifies a large number of cellular proteins. SUMO modification has emerged as an important regulatory mechanism for protein function and localization. SUMOylation is a dynamic process that is mediated by activating (E1), conjugating (E2), and ligating (E3) enzymes and readily reversed by a family of ubiquitin-like protein-specific proteases (Ulp) in yeast and sentrin/SUMO-specific proteases (SENP) in human. This review will focus on the de-SUMOylating enzymes with special attention to their biological function.

摘要

小泛素样修饰蛋白(SUMO)是一种类泛素蛋白,可共价修饰大量细胞蛋白。SUMO修饰已成为蛋白质功能和定位的重要调控机制。SUMO化是一个动态过程,由激活酶(E1)、缀合酶(E2)和连接酶(E3)介导,并可被酵母中的泛素样蛋白特异性蛋白酶家族(Ulp)和人类中的sentrin/SUMO特异性蛋白酶(SENP)轻易逆转。本综述将聚焦于去SUMO化酶,特别关注它们的生物学功能。
