摘要

冠状病毒的蛋白质分为非结构蛋白、结构蛋白和辅助蛋白。除了它们的前体外,还有16种非结构病毒蛋白(1a和1ab多聚蛋白)。这些非结构蛋白被命名为nsp1到nsp16,它们作为酶、辅酶和结合蛋白来促进病毒的复制、转录和翻译。结构蛋白与核衣壳中的RNA (N-蛋白)或病毒包膜的脂质双层膜结合。脂质双分子层蛋白包括膜蛋白(M)、包膜蛋白(E)和刺突蛋白(S)。它们除了作为结构蛋白的作用外,还对宿主细胞的结合和侵袭至关重要。SARS-CoV-2包含6个辅助蛋白,参与病毒复制、组装和病毒与宿主的相互作用。SARS-CoV-2的附属蛋白为orf3a、orf6、orf7a、orf7b、orf8和orf10。SARS-CoV-2的功能尚不为人所知,其在SARS-CoV中相应蛋白的功能要么为人所知,要么研究不足。最近,牛津大学和阿斯利康、辉瑞、BioNTech等公司都以刺突蛋白基因为靶点,研制出了SARS-CoV-2疫苗。美国食品和药物管理局(FDA)和英国卫生当局已经批准并开始使用辉瑞和BioNTech mRNA疫苗进行疫苗接种。此外,美国FDA已批准使用Regeneron制药公司生产的两种单克隆抗体,以靶向刺突蛋白治疗COVID-19。SARS-CoV-2蛋白可用于诊断、药物靶标和COVID-19疫苗试验。在未来的新冠病毒研究中,应进一步阐明SARS-CoV- 2蛋白的功能和结构,将其作为新冠病毒药物和疫苗的靶点。特别要关注SARS-CoV-2 nsp3、orf8和orf10的广泛研究。

关键词: nsp3,刺突蛋白,orf3, orf8, orf10, sars冠状病毒。
