Function
Q89920_HHV2 Envelope glycoprotein that forms spikes at the surface of virion envelope and binds to the host cell entry receptors MYH9/NMMHC-IIA and MYH10/NMMHC-IIB, promoting the virus entry into host cells. Essential for the initial attachment to heparan sulfate moieties of the host cell surface proteoglycans. Involved in fusion of viral and cellular membranes leading to virus entry into the host cell: following initial binding to its host cell entry receptors, membrane fusion is mediated by the fusion machinery composed at least of gB and the heterodimer gH/gL. May be involved in the fusion between the virion envelope and the outer nuclear membrane during virion egress. Also plays a role, together with gK, in virus-induced cell-to-cell fusion (syncytia formation).[ARBA:ARBA00055014]
