病毒的 nonstructural 蛋白质在包并且非包的病毒在病毒的复制起重要作用。草鲤鱼 reovirus (GCRV ) 的蛋白质 NS38,被推出了是非结构的蛋白质,并且,与另外的 reoviruses 一致,被认为在病毒的粒子汇编与 NS80 蛋白质合作。调查 NS38 的角色的分子的基础,完全的蛋白质第一次在 E.coli 被表示。有在 28 掳 C 而非 37 掳 C 与 IPTG 导致的 NS38 的更好的表情,这被发现。另外,与净化的熔化蛋白质准备并且注入了兔子的 NS38 的抗血清能被用于在 GCRV 检测 NS38 蛋白质表示当没有任何反应,与净化的病毒粒子穿过时,感染了房间 lysate,证实 NS38 不是病毒的结构的蛋白质的一个部件。结果在这报导学习将在 dsRNA 病毒复制为进一步病毒的蛋白质蛋白质和 protein-RNA 相互作用提供证据。关键词草鲤鱼 reovirus (GCRV )- Nonstructural 蛋白质 NS38 - Recombinant 表示基础项目:中国(2009CB118701 ) 的国家基本研究节目(973 ) ;中国的国家自然科学基础(30871940, 30671615 ) 。
Viral nonstructural proteins in both enveloped and non-enveloped viruses play important roles in viral replication. Protein NS38 of Grass carp reovirus (GCRV), has been deduced to be a non-structural protein, and, consistent with other reoviruses, is considered to cooperate with the NS80 protein in viral particle assembly. To investigate the molecular basis of the role ofNS38, a complete protein was expressed in E.coli for the first time. It was found that there is a better expression of NS38 induced with IPTG at 28℃ rather than 37℃. In addition, the antiserum of NS38 prepared with purified fusion protein and injected into rabbit could be used for detecting NS38 protein expression in GCRV infected cell lysate, while there is not any reaction crossed with purified virus particle, confirming NS38 is not a component of the viral structural protein. The result reported in this study will provide evidence for further viral protein-protein and protein-RNA interaction in dsRNA viruses replication
