| 释义 | spike protein noun[ C or U ] biology specializeduk /ˈspaɪk ˌprəʊ.tiːn/ us /ˈspaɪk ˌproʊ.tiːn/ a glycoprotein(= a type of protein that contains a carbohydrate group) that forms a structure that sticks out on the outer edge of a virus, which helps the virus to attach itself to a cell in a person's or animal's body and enter the cell: （病毒表面的）刺突蛋白 Members of the coronavirus family have sharp bumps known as spike proteins that protrude from the surface of their outer envelopes. 冠状病毒科的成员在外壳蛋白表面上有尖锐的突起，被称为刺突蛋白。 The emergence of SARS was probably linked to the adaptation of spike protein to bind strongly to human cells.SARS的出现可能与刺突蛋白结构发生调整使之与人类细胞结合能力加强相关。 Prof Rottier has developed small protein fragments, called peptides, that can attach to these "spike proteins", blocking the entry into cat cells of feline coronavirus. The SARS spike protein gene underwent rapid change, particularly at the beginning of the epidemic. Their research confirmed that the new virus’s spike protein clings to its target on human cells 10 to 20 times as tightly as the SARS spike protein does. After the spike protein binds to the human cell receptor, the viral membrane fuses with the human cell membrane, allowing the genome of the virus to enter human cells and begin infection.
