The virus contains a surface '''glycoprotein PG''' that is responsible for binding to target cells and subsequent fusion of viral and host-cell membranes. GP is expressed as a single-chain precursor that is posttranslationally processed into disulfide-linked fragments of '''GP1''' and '''GP2''' <ref>PMID:10077567</ref>. Viral infections is initiated by interactions between the viral protein glycoprotein PG1 and its cognate receptor. The GP2 subunit is thought to mediate membrane fusion.
