Envelope glycoprotein that forms spikes at the surface of the virion envelope. It is essential for the initial attachment to heparan sulfate moieties of host cell surface proteoglycans. Involved in the fusion of viral and cellular membranes, leading to virus entry into the host cell. Membrane fusion is mediated by the fusion machinery, including gB and the heterodimer gH/gL, following initial binding to host receptors.
