RX PubMed=2841484; RA Whitbeck J.C., Bello L.J., Lawrence W.C.; RT "Comparison of the bovine herpesvirus 1 gI gene and the herpes simplex RT virus type 1 gB gene."; RL J. Virol. 62:3319-3327(1988). CC -!- FUNCTION: Envelope glycoprotein that forms spikes at the surface of CC virion envelope. Essential for the initial attachment to heparan CC sulfate moieties of the host cell surface proteoglycans. Involved in CC fusion of viral and cellular membranes leading to virus entry into the CC host cell. Following initial binding to its host receptors, membrane CC fusion is mediated by the fusion machinery composed at least of gB and CC the heterodimer gH/gL. May be involved in the fusion between the virion CC envelope and the outer nuclear membrane during virion egress. CC {ECO:0000255|HAMAP-Rule:MF_04032}. CC -!- SUBUNIT: Homotrimer; disulfide-linked. Binds to heparan sulfate CC proteoglycans. Interacts with gH/gL heterodimer. {ECO:0000255|HAMAP- CC Rule:MF_04032}. CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000255|HAMAP- CC Rule:MF_04032}; Single-pass type I membrane protein {ECO:0000255|HAMAP- CC Rule:MF_04032}. Host cell membrane {ECO:0000255|HAMAP-Rule:MF_04032}; CC Single-pass type I membrane protein {ECO:0000255|HAMAP-Rule:MF_04032}. CC Host endosome membrane {ECO:0000255|HAMAP-Rule:MF_04032}; Single-pass CC type I membrane protein {ECO:0000255|HAMAP-Rule:MF_04032}. Host Golgi CC apparatus membrane {ECO:0000255|HAMAP-Rule:MF_04032}; Single-pass type CC I membrane protein {ECO:0000255|HAMAP-Rule:MF_04032}. Note=During CC virion morphogenesis, this protein probably accumulates in the CC endosomes and trans-Golgi where secondary envelopment occurs. It is CC probably transported to the cell surface from where it is endocytosed CC and directed to the trans-Golgi network (TGN). {ECO:0000255|HAMAP- CC Rule:MF_04032}. CC -!- PTM: A proteolytic cleavage by host furin generates two subunits that CC remain linked by disulfide bonds. {ECO:0000305}. CC -!- SIMILARITY: Belongs to the herpesviridae glycoprotein B family. CC {ECO:0000255|HAMAP-Rule:MF_04032}.
