Enterovirus 70 (EV70), like several other human enteroviruses, can utilize decay-accelerating factor (DAF [CD55]) as an attachment protein. Using chimeric molecules composed of different combinations of the short consensus repeat domains (SCRs) of DAF and membrane cofactor protein (CD46), we show that sequences in SCR1 of DAF are essential for EV70 binding. Of the human enteroviruses that can bind to DAF, only EV70 and coxsackievirus A21 require sequences in SCR1 for this interaction.
肠道病毒70型(EV70)与其他几种人类肠道病毒一样,可利用衰变加速因子(DAF [CD55])作为附着蛋白。我们使用由DAF和膜辅因子蛋白(CD46)的短共有重复序列结构域(SCR)的不同组合组成的嵌合分子,证明DAF的SCR1中的序列对于EV70结合至关重要。在可与DAF结合的人类肠道病毒中,只有EV70和柯萨奇病毒A21型需要SCR1中的序列进行这种相互作用。
