冠状病毒是具有包膜的正链RNA病毒，SARS-CoV-2就是一种冠状病毒，其传播和扩散给世界健康和经济带来了巨大影响，冠状病毒的非结构性蛋白1（Nsp1）可以抑制宿主蛋白质合成，SARS-CoV-2的Nsp1 C端结构域可以结合核糖体的mRNA通道来抑制翻译，但是该机制在冠状病毒中是否广泛存在，Nsp1的N端结构域是否结合核糖体，以及...
(1). The NSPs are involved in the replication and transcription of the viral RNA and not incorporated within the virion particles. Coronaviruses include various highly pathogenic strains such as SARS-CoV, MERS-CoV and SARS-CoV2 that have had significant impact on humans as well as strains ...

事实上,Nsp1是这种病毒用来确保自身在人类宿主中复制和传播的核心武器之一。近20年前,与SARS-CoV-2存在亲缘关系的SARS-CoV冠状病毒疫情爆发后,Nsp1就已被确认为一种致病因子,在当时它被发现能抑制受感染细胞的蛋白合成。 在一项新的研究中,来自德国慕尼黑大学和乌尔姆大学医学中心的研究人员确定了大流行性冠状病毒SAR...

We found that in infected cells, there was limited IRF3 and NF-κB nuclear translocation, suggesting SARS-CoV-2 can limit immune activation. Additionally, through promoter luciferase signaling assays, the viral proteins NSP1, the host translation shutoff factor, and NSP13, the RNA helicase, can...
近日,耶鲁大学熊勇教授团队在国际知名期刊Molecular Cell上发表了研究论文“Nonstructural protein 1 of SARS-CoV-2 is a potent pathogenicity factor redirecting host protein synthesis machinery toward viral RNA”,研究人员通过筛选新冠病毒蛋白和转...
The SARS-CoV-2 non-structural protein 1 (Nsp1), also referred to as the host shutoff factor, suppresses host innate immune functions. By combining cryo-electron microscopy and biochemistry, we show that SARS-CoV-2 Nsp1 binds to the human 40S subunit in ribosomal complexes, including the 43...
While SARS-CoV-2 is causing modern human history’s most serious health crisis and upending our way of life, clinical and basic research on the virus is advancing rapidly, leading to fascinating discoveries. Two studies have revealed how the viral virule
