Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.

SARS-CoV属于巢状病毒目、冠状病毒科，为单正链RNA病毒，基因组全长约29.7kb，已知编码11种蛋白，其中包括4种结构蛋白，分别是刺突蛋白、包膜蛋白、小包膜蛋白和核蛋白或核壳体蛋白。S蛋白三聚体形成突起，伸出包膜表面。S蛋白是病毒的主要表面抗原成分，具有受体结合和膜融合活性，在组织嗜性、细胞融合和毒力等方面起重要作用。N蛋白与基因组RNA结合形成核衣壳。M蛋白和E蛋白是包膜形成所必需的成分。
