Function

Envelope glycoprotein that forms spikes at the surface of virion envelope. 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.

Biological Context

Subcellular Location: Virion membrane (Single-pass type I membrane protein); Host cell membrane (Single-pass type I membrane protein); Host endosome membrane (Single-pass type I membrane protein); Host Golgi apparatus membrane (Single-pass type I membrane protein)

Function

Envelope glycoprotein that forms spikes at the surface of virion envelope. 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 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

Subcellular Location

Virion membrane (Single-pass type I membrane protein); Host cell membrane (Single-pass type I membrane protein); Host endosome membrane (Single-pass type I membrane protein); Host Golgi apparatus membrane (Single-pass type I membrane protein)

Subunit

Homotrimer; disulfide-linked. Binds to heparan sulfate proteoglycans. Interacts with gH/gL heterodimer

Gene: gB  |  Organism: Epstein-Barr virus (strain B95-8)
