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}.
