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. Acts as a functional inhibitor of gH and maintains gH in
CC       an inhibited form. Upon binding to host integrins, gL dissociates from
CC       gH leading to activation of the viral fusion glycoproteins gB and gH.
CC       {ECO:0000255|HAMAP-Rule:MF_04034}.
CC   -!- SUBUNIT: Interacts with glycoprotein H (gH); 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_04034}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane {ECO:0000255|HAMAP-
CC       Rule:MF_04034}; Peripheral membrane protein {ECO:0000255|HAMAP-
CC       Rule:MF_04034}; Extracellular side {ECO:0000255|HAMAP-Rule:MF_04034}.
CC       Host cell membrane {ECO:0000255|HAMAP-Rule:MF_04034}; Peripheral
CC       membrane protein {ECO:0000255|HAMAP-Rule:MF_04034}; Extracellular side
CC       {ECO:0000255|HAMAP-Rule:MF_04034}. Host Golgi apparatus, host trans-
CC       Golgi network {ECO:0000255|HAMAP-Rule:MF_04034}. Note=gL associates
CC       with the extravirion surface through its binding to gH. During virion
CC       morphogenesis, this protein probably accumulates in the host trans-
CC       Golgi where secondary envelopment occurs. {ECO:0000255|HAMAP-
CC       Rule:MF_04034}.
CC   -!- SIMILARITY: Belongs to the herpesviridae glycoprotein L family.
CC       {ECO:0000255|HAMAP-Rule:MF_04034}.
