Pike protein consists of S1 and S2 subunit. S1 is head and S2 is rod-shape part, intermolecular effort can bind each other. S1 can bind with host cell epimembranal acceptor. S2 can fix integral Spike protein on the cellular membrane and mediate cell-fusion with virus and host cell. There are significant antigen determinant of virus in Spike protein, genic heterogenesis can effect viral pathogenicity. SARS-CoV Spike protein, which has 23 pieces larvaceous glycosylation sit, consists of 1256 amino acid. Its N-terminals and C-terminals is corresponding conservative.
蛋白是I型膜糖蛋白,介导病毒与宿主细胞膜上的受体结合并与宿主细胞膜相融合。S蛋白由S1和S2两个亚基组成。S1形成球状部分,S2形成棒状部分,两者之间通过分子间的作用力相互结合。S1能与宿主细胞上的受体结合,S2可把整个S蛋白固定在细胞膜上,并介导病毒包膜与宿主细胞膜融合。S蛋白上有重要的病毒抗原决定簇,S基因的突变会影响病毒的致病性。
