CC -!- FUNCTION: Envelope glycoprotein that plays a role in host cell entry,
CC cell to-cell virus transmission, and fusion of infected cells. May be
CC involved in the initial attachment via binding to heparan sulfate
CC together with the gM/gN complex that binds heparin with higher
CC affinity. Interacts with host integrin ITGB1, PDGFRA and EGFR that
CC likely serve as postattachment entry receptors. Participates also in
CC the fusion of viral and cellular membranes leading to virus entry into
CC the host cell. Membrane fusion is mediated by the fusion machinery
CC composed at least of gB and the heterodimer gH/gL.
CC {ECO:0000269|PubMed:12433371, ECO:0000269|PubMed:19193805}.
CC -!- SUBUNIT: Homotrimer; disulfide-linked. Binds to heparan sulfate
CC proteoglycans. Interacts with gH/gL heterodimer (By similarity).
CC Interacts with host TLR1 and TLR2. Interacts with host C-type lectin
CC CD209/DC-SIGN. Interacts with host ITGB1, EGFR, and PDGFRA.
CC {ECO:0000255|HAMAP-Rule:MF_04032, ECO:0000269|PubMed:12433371,
CC ECO:0000269|PubMed:17082626, ECO:0000269|PubMed:20660204}.
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:0000250}.
CC -!- SIMILARITY: Belongs to the herpesviridae glycoprotein B family.
CC {ECO:0000255|HAMAP-Rule:MF_04032}.
