CC -!- FUNCTION: The heterodimer glycoprotein H-glycoprotein L is required for
CC the fusion of viral and plasma membranes leading to virus entry into
CC the host cell. Following initial binding to host receptor, membrane
CC fusion is mediated by the fusion machinery composed of gB and the
CC heterodimer gH/gL. May also be involved in the fusion between the
CC virion envelope and the outer nuclear membrane during virion
CC morphogenesis. {ECO:0000255|HAMAP-Rule:MF_04033}.
CC -!- SUBUNIT: Interacts with glycoprotein L (gL); this interaction is
CC necessary for the correct processing and cell surface expression of gH.
CC The heterodimer gH/gL seems to interact with gB trimers during fusion.
CC {ECO:0000255|HAMAP-Rule:MF_04033}.
CC -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000255|HAMAP-
CC Rule:MF_04033}; Single-pass type I membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_04033}. Host cell membrane {ECO:0000255|HAMAP-Rule:MF_04033};
CC Single-pass type I membrane protein {ECO:0000255|HAMAP-Rule:MF_04033}.
CC Host endosome membrane {ECO:0000255|HAMAP-Rule:MF_04033}; Single-pass
CC type I membrane protein {ECO:0000255|HAMAP-Rule:MF_04033}. 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_04033}.
CC -!- PTM: N-glycosylated, O-glycosylated, and sialylated.
CC {ECO:0000255|HAMAP-Rule:MF_04033}.
CC -!- SIMILARITY: Belongs to the herpesviridae glycoprotein H family.
CC {ECO:0000255|HAMAP-Rule:MF_04033}.
