CC -!- FUNCTION: [Glycoprotein G2]: Class I viral fusion protein that directs
CC fusion of viral and host endosomal membranes, leading to delivery of
CC the nucleocapsid into the cytoplasm. Membrane fusion is mediated by
CC irreversible conformational changes induced upon acidification in the
CC endosome. {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- FUNCTION: Stable signal peptide (SSP): cleaved and functions as a
CC signal peptide. In addition, it is also retained as the third component
CC of the GP complex. The SSP is required for efficient glycoprotein
CC expression, post-translational maturation cleavage of GP1 and GP2,
CC glycoprotein transport to the cell surface plasma membrane, formation
CC of infectious virus particles, and acid pH-dependent glycoprotein-
CC mediated cell fusion. {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- FUNCTION: [Glycoprotein G1]: Interacts with the host receptor.
CC {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- SUBUNIT: [Glycoprotein G1]: Homotetramer; disulfide-linked.
CC {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- SUBUNIT: [Glycoprotein G2]: Homotetramer. GP2 homotetramers bind
CC through ionic interactions with GP1 homotetramers to form the GP
CC complex together with the stable signal peptide. The GP-C polyprotein
CC interacts with the host protease MBTPS1/SKI-1 resulting in the
CC polyprotein processing. {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- SUBCELLULAR LOCATION: [Glycoprotein G1]: Virion membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Peripheral membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host endoplasmic reticulum membrane

CC {ECO:0000255|HAMAP-Rule:MF_04084}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host endoplasmic reticulum membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host Golgi apparatus membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host cell membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Single-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Note=Binding to the stable signal
CC peptide masks endogenous ER localization signals in the cytoplasmic
CC domain of G2 to ensure that only the fully assembled, tripartite GP
CC complex is transported for virion assembly. {ECO:0000255|HAMAP-
CC Rule:MF_04084}.
CC -!- SUBCELLULAR LOCATION: [Stable signal peptide]: Virion membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host endoplasmic reticulum membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host Golgi apparatus membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}. Host cell membrane
CC {ECO:0000255|HAMAP-Rule:MF_04084}; Multi-pass membrane protein
CC {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- DOMAIN: The cytoplasmic domain of GP2 plays a role in ER location. It
CC also contains a zinc-binding domain that allows SSP retention in the
CC GPC complex by accepting a cysteine from SSP as the fourth ligand.
CC {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- PTM: Specific enzymatic cleavages in vivo yield mature proteins. GP-C
CC polyprotein is cleaved in the endoplasmic reticulum by the host
CC protease MBTPS1. Only cleaved glycoprotein is incorporated into
CC virions. {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- PTM: The SSP remains stably associated with the GP complex following
CC cleavage by signal peptidase and plays crucial roles in the trafficking
CC of GP through the secretory pathway. {ECO:0000255|HAMAP-Rule:MF_04084}.
CC -!- SIMILARITY: Belongs to the arenaviridae GPC protein family.
CC {ECO:0000255|HAMAP-Rule:MF_04084}.
