Glycoprotein GP

Function

The virus contains a surface glycoprotein GP or envelope glycoprotein GP 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 ^[1]. 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.

For details see GP1 of Lassa Virus.
