Research progress on role of envelope protein in morphogenesis of vaccinia virus / 中国生物制品学杂志

ABSTRACT

@#The vaccinia virus(VACV),which belongs to the genus Orthopoxvirus, is utilized as a model virus in various studies and displays the usual traits of its kind.VACV has a genome of about 200 000 bp and contains a highly conserved central coding region sequence(CRS),which can encode key proteins in various stages of virus morphogenesis.Among them,the main envelope proteins related to morphogenesis include A13L,A17L,A27L,A28L and A36R,playing an important role in the morphogenesis of VACV.In this review,the research progress on the role of envelope proteins in the morphogenesis process of VACV membrane such as attachment and membrane fusion,virus particle assembly,intracellular movement of intracellular mature virus(IMV),and intercellular transmission of extracellular enveloped virus(EEV) is reviewed,so as to provide theoretical basis for further exploring the pathogenesis of VACV and other orthopoxviruses(such as monkeypox virus(MPXV),developing antiviral drugs and effectively preventing virus infection.
