CC   -!- FUNCTION: [Glycoprotein N]: Forms homotetramers with glycoprotein C at
CC       the surface of the virion (By similarity). Attaches the virion to host
CC       cell receptors including integrin ITGAV/ITGB3 (By similarity). This
CC       attachment induces virion internalization predominantly through
CC       clathrin-dependent endocytosis (By similarity). Mediates the assembly
CC       and budding of infectious virus particles through its interaction with
CC       the nucleocapsid protein and the viral genome (By similarity). May
CC       dysregulate normal immune and endothelial cell responses through an
CC       ITAM motif (By similarity). Translocates to mitochondria, binds to host
CC       TUFM and recruits MAP1LC3B (By similarity). These interactions induce
CC       mitochondrial autophagy and therefore destruction of host MAVS leading
CC       to inhibition of type I interferon (IFN) responses (By similarity).
CC       Concomitant breakdown of glycoprotein N is apparently prevented by the
CC       nucleoprotein that may inhibit Gn-stimulated autophagosome-lysosome
CC       fusion (By similarity). Interacts with the viral genomic RNA (By
CC       similarity). {ECO:0000250|UniProtKB:P08668,
CC       ECO:0000250|UniProtKB:P27312}.

CC       including integrin ITGAV/ITGB3. This attachment induces virion
CC       internalization predominantly through clathrin-dependent endocytosis.
CC       Class II fusion protein that promotes fusion of viral membrane with
CC       host endosomal membrane after endocytosis of the virion.
CC       {ECO:0000250|UniProtKB:P08668}.
CC   -!- SUBUNIT: [Glycoprotein N]: Homodimer (By similarity). Homotetramer;
CC       forms heterotetrameric Gn-Gc spikes in the pre-fusion conformation (By
CC       similarity). Interacts (via C-terminus) with the nucleoprotein (By
CC       similarity). Interacts with host TUFM; this interaction contributes to
CC       the virus-induced degradation of mitochondria by autophagy, which leads
CC       to degradation of host MAVS and inhibition of type I interferon (IFN)
CC       responses (By similarity). Interacts with host MAP1LC3B; this
CC       interaction contributes to the virus-induced degradation of
CC       mitochondria by autophagy, which leads to degradation of host MAVS and
CC       inhibition of type I interferon (IFN) responses (By similarity).

CC   -!- SUBUNIT: [Glycoprotein C]: Homodimer. Homotetramer; forms
CC       heterotetrameric Gn-Gc spikes in the pre-fusion conformation.
CC       Homotrimer; forms homotrimer in the post-fusion conformation at acidic
CC       pH (By similarity). Interacts (via C-terminus) with the nucleoprotein
CC       (By similarity). {ECO:0000250|UniProtKB:P08668,

CC   -!- SUBCELLULAR LOCATION: [Glycoprotein N]: Virion membrane
CC       {ECO:0000250|UniProtKB:P08668}; Multi-pass membrane protein. Host cell
CC       surface {ECO:0000250|UniProtKB:P08668}. Host Golgi apparatus membrane
CC       {ECO:0000250|UniProtKB:P08668}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P08668}. Host endoplasmic reticulum membrane
CC       {ECO:0000250|UniProtKB:P08668}; Multi-pass membrane protein
CC       {ECO:0000250|UniProtKB:P08668}. Host mitochondrion
CC       {ECO:0000250|UniProtKB:P08668}. Note=Interaction between glycoprotein N
CC       and glycoprotein C is essential for proper targeting of glycoprotein N
CC       to the host Golgi complex, where virion budding occurs.
CC       {ECO:0000250|UniProtKB:P27312}.
CC   -!- SUBCELLULAR LOCATION: [Glycoprotein C]: Virion membrane
CC       {ECO:0000250|UniProtKB:P08668}; Single-pass type I membrane protein.
CC       Host cell surface {ECO:0000250|UniProtKB:P08668}. Host Golgi apparatus
CC       membrane {ECO:0000250|UniProtKB:P08668}; Single-pass type I membrane
CC       protein {ECO:0000250|UniProtKB:P08668}. Host endoplasmic reticulum
CC       membrane {ECO:0000250|UniProtKB:P08668}; Single-pass type I membrane
CC       protein {ECO:0000250|UniProtKB:P08668}. Note=Budding probably takes
CC       place at the host Golgi (Probable). Glycoprotein C cytoplasmic tail is
CC       important for efficient Golgi localization (By similarity).
CC       {ECO:0000250|UniProtKB:P08668, ECO:0000305}.
CC   -!- DOMAIN: [Glycoprotein N]: The YxxL motif at the C-terminus is
CC       indispensable for the interaction with MAP1LC3B and for the Gn-mediated
CC       induction of mitochondrial autophagy (By similarity). The cytoplasmic
CC       tail is involved in the inhibition of the host innate immune response
CC       (By similarity). The C-terminus of the cytoplasmic tail is involved in
CC       binding to the viral genome and the nucleocapsid (By similarity).
CC       Contains 2 contiguous zinc-fingers (By similarity).
CC       {ECO:0000250|UniProtKB:P08668, ECO:0000250|UniProtKB:P0DTJ1,
CC       ECO:0000250|UniProtKB:P27312, ECO:0000250|UniProtKB:Q9E006}.
CC   -!- DOMAIN: [Glycoprotein C]: The C-terminus is necessary for proper
CC       localization in the Golgi (By similarity). The cytoplasmic tail is
CC       involved in binding to the nucleocapsid (By similarity).
CC       {ECO:0000250|UniProtKB:P27312}.
CC   -!- PTM: [Envelopment polyprotein]: Envelope polyprotein precursor is
CC       quickly cleaved in vivo just after synthesis, presumably by host signal
CC       peptidase. {ECO:0000250|UniProtKB:P08668}.
CC   -!- SIMILARITY: Belongs to the hantavirus envelope glycoprotein family.
CC       {ECO:0000305}.
