【摘要】 蛋白质泛素化作为一种重要的翻译后修饰,通过介导特定蛋白质的降解,广泛地参与到植物生长发育、胁迫响应、信号转导等一系列生命活动过程中,在植物的生命周期中具有重要意义。E3泛素连接酶能够特异性地识别靶蛋白,在泛素化途径中起决定性作用。因此,研究植物E3泛素连接酶的功能及其作用机理具有重要的意义。该文介绍了目前E3泛素连接酶分类与功能方面的研究进展,为深入探讨E3泛素连接酶在植物生命活动过程中的调控机制提供借鉴。更多还原

【Abstract】 Protein ubiquitination mediates the degradation of specific proteins as an important posttranslation modification,which is widely involved in a series of life processes,such as plant growth and development,stress response,signal transduction,etc.E3 ubiquitin ligase can specifically recognize target proteins and play a decisive role in the ubiquitin pathway.Therefore,it is of great significance to study the function and mechanism of plant E3 ubiquitin ligase.In this paper,the progress in the classification and function of E3 ubiquitin ligase are reviewed in order to provide references for further exploring the regulation mechanism of E3 ubiquitin ligase in plants.更多还原
