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 -!- SIMILARITY: Belongs to the herpesviridae glycoprotein B family.
CC {ECO:0000255|HAMAP-Rule:MF_04032}.
