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 -!- FUNCTION: [Glycoprotein C]: Forms homotetramers with glycoprotein N at
CC the surface of the virion. Attaches the virion to host cell receptors
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 {ECO:0000250|UniProtKB:P08668, ECO:0000250|UniProtKB:P0DTJ1}.
CC -!- SUBUNIT: [Glycoprotein C]: Homodimer. Homotetramer; forms
CC heterotetrameric Gn-Gc spikes in the pre-fusion conformation (By

CC conformation at acidic pH (By similarity). Interacts (via C-terminus)
CC with the nucleoprotein (By similarity). {ECO:0000250|UniProtKB:P08668,

CC localization (By similarity). {ECO:0000250|UniProtKB:P08668,
CC 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}.
