摘要:

泛素化是蛋白质的翻译后共价修饰过程,可以调节蛋白质的稳定性,涉及多种生理功能。痘病毒在进化过程中形成了扰乱和操纵宿主细胞泛素系统的多种机制,包括编码多种能干扰宿主泛素系统的病毒蛋白质。近年的研究表明痘病毒编码许多具有泛素连接酶活性的蛋白质,如膜相关RING-CH(MARCH)结构域蛋白、p28/Really Interesting New Gene(RING)finger蛋白、锚蛋白重复序列/F-box蛋白、Bric-a-Brac Tramtrack Broad complex(BTB)/Kelch蛋白及APC家族蛋白等。作者在本文着重阐述了痘病毒编码的E3泛素连接酶功能蛋白的研究概况。

Abstract:

Ubiquitylation is a covalent post-translational modification that regulates protein stability and is involved in many biological functions.Many poxviruses have evolved multiple mechanisms to perturb the cell ubiquitin system and manipulate it to their own benefit.Such as the poxvirus family encode ubiquitin ligases with intrinsic activity,including the membrane-associated RING-CH(MARCH) domain,p28/Really Interesting New Gene(RING) finger,ankyrin-repeat/F-box and Broad-complex,Tramtrack and Bric-a-Brac(BTB)/Kelch subgroups of the E3 Ub ligase superfamily.Here we describe and discuss the proteins with E3 ubiquitin ligase function encoded by poxvirus.
