CC -!- FUNCTION: [Capsid protein C]: Plays a role in virus budding by binding CC to the cell membrane and gathering the viral RNA into a nucleocapsid CC that forms the core of a mature virus particle (By similarity). During CC virus entry, may induce genome penetration into the host cytoplasm CC after hemifusion induced by the surface proteins (By similarity). Can CC migrate to the cell nucleus where it modulates host functions (By CC similarity). Overcomes the anti-viral effects of host EXOC1 by CC sequestering and degrading the latter through the proteasome CC degradation pathway (PubMed:23522008). {ECO:0000250|UniProtKB:P17763, CC ECO:0000269|PubMed:23522008}. CC -!- FUNCTION: [Capsid protein C]: Inhibits RNA silencing by interfering CC with host Dicer. {ECO:0000250|UniProtKB:P03314}. CC -!- FUNCTION: [Peptide pr]: Prevents premature fusion activity of envelope CC proteins in trans-Golgi by binding to envelope protein E at pH6.0. CC After virion release in extracellular space, gets dissociated from E CC dimers. {ECO:0000250|UniProtKB:P17763}. CC -!- FUNCTION: [Protein prM]: Acts as a chaperone for envelope protein E CC during intracellular virion assembly by masking and inactivating CC envelope protein E fusion peptide. prM is the only viral peptide CC matured by host furin in the trans-Golgi network probably to avoid CC catastrophic activation of the viral fusion activity in acidic Golgi CC compartment prior to virion release. prM-E cleavage is inefficient, and CC many virions are only partially matured. These uncleaved prM would play CC a role in immune evasion. {ECO:0000250|UniProtKB:P17763}. CC -!- FUNCTION: [Small envelope protein M]: May play a role in virus budding. CC Exerts cytotoxic effects by activating a mitochondrial apoptotic CC pathway through M ectodomain. May display a viroporin activity. CC {ECO:0000250|UniProtKB:P17763}. CC -!- FUNCTION: [Envelope protein E]: Binds to host cell surface receptor and CC mediates fusion between viral and cellular membranes (PubMed:15367621). CC Envelope protein is synthesized in the endoplasmic reticulum in the CC form of heterodimer with protein prM (By similarity). They play a role CC in virion budding in the ER, and the newly formed immature particle is CC covered with 60 spikes composed of heterodimer between precursor prM CC and envelope protein E (By similarity). The virion is transported to CC the Golgi apparatus where the low pH causes dissociation of PrM-E CC heterodimers and formation of E homodimers (By similarity). prM-E CC cleavage is inefficient, and many virions are only partially matured CC (By similarity). These uncleaved prM would play a role in immune CC evasion (By similarity). {ECO:0000250|UniProtKB:P17763}. CC -!- FUNCTION: [Non-structural protein 1]: Involved in immune evasion, CC pathogenesis and viral replication. Once cleaved off the polyprotein, CC is targeted to three destinations: the viral replication cycle, the CC plasma membrane and the extracellular compartment. Essential for viral CC replication. Required for formation of the replication complex and CC recruitment of other non-structural proteins to the ER-derived membrane CC structures. Excreted as a hexameric lipoparticle that plays a role CC against host immune response. Antagonizing the complement function. CC Binds to the host macrophages and dendritic cells. Inhibits signal CC transduction originating from Toll-like receptor 3 (TLR3). CC {ECO:0000250|UniProtKB:Q9Q6P4}. CC -!- FUNCTION: [Non-structural protein 2A]: Component of the viral RNA CC replication complex that functions in virion assembly and antagonizes CC the host alpha/beta interferon antiviral response. CC {ECO:0000250|UniProtKB:P14335}. CC -!- FUNCTION: [Serine protease subunit NS2B]: Required cofactor for the CC serine protease function of NS3. May have membrane-destabilizing CC activity and form viroporins (By similarity). CC {ECO:0000250|UniProtKB:P17763, ECO:0000255|PROSITE-ProRule:PRU00859}. CC -!- FUNCTION: [Serine protease/Helicase NS3]: Displays three enzymatic CC activities: serine protease, NTPase and RNA helicase. NS3 serine CC protease, in association with NS2B, performs its autocleavage and CC cleaves the polyprotein at dibasic sites in the cytoplasm: C-prM, NS2A- CC NS2B, NS2B-NS3, NS3-NS4A, NS4A-2K and NS4B-NS5. NS3 RNA helicase binds CC RNA and unwinds dsRNA in the 3' to 5' direction (By similarity). NS3 CC supports the separation of RNA daughter and template strands during CC viral replication. The helicase part is involved in the inhibition of CC phosphorylation of host STAT1, and thereby inhibition of host type-I CC IFN signaling (By similarity). In addition, NS3 assists the initiation CC of replication by unwinding the RNA secondary structure in the 3' non- CC translated region (NTR). Inhibits STAT2 translocation in the nucleus CC after IFN-alpha treatment (By similarity). CC {ECO:0000250|UniProtKB:P14335, ECO:0000250|UniProtKB:Q9Q6P4, CC ECO:0000255|PROSITE-ProRule:PRU00860}. CC -!- FUNCTION: [Non-structural protein 4A]: Regulates the ATPase activity of CC the NS3 helicase activity. NS4A allows NS3 helicase to conserve energy CC during unwinding. {ECO:0000250|UniProtKB:Q9Q6P4}. CC -!- FUNCTION: [Peptide 2k]: Functions as a signal peptide for NS4B and is CC required for the interferon antagonism activity of the latter. CC {ECO:0000250|UniProtKB:P17763}. CC -!- FUNCTION: [Non-structural protein 4B]: Induces the formation of ER- CC derived membrane vesicles where the viral replication takes place. CC Inhibits interferon (IFN)-induced host STAT1 phosphorylation and CC nuclear translocation, thereby preventing the establishment of cellular CC antiviral state by blocking the IFN-alpha/beta pathway. Inhibits STAT2 CC translocation in the nucleus after IFN-alpha treatment. CC {ECO:0000250|UniProtKB:Q9Q6P4}. CC -!- FUNCTION: [RNA-directed RNA polymerase NS5]: Replicates the viral (+) CC and (-) RNA genome, and performs the capping of genomes in the CC cytoplasm (PubMed:17267492). NS5 methylates viral RNA cap at guanine N- CC 7 and ribose 2'-O positions (PubMed:17267492). Besides its role in RNA CC genome replication, also prevents the establishment of cellular CC antiviral state by blocking the interferon-alpha/beta (IFN-alpha/beta) CC signaling pathway (By similarity). Inhibits host TYK2 and STAT2 CC phosphorylation, thereby preventing activation of JAK-STAT signaling CC pathway (By similarity). {ECO:0000250|UniProtKB:Q9Q6P4, CC ECO:0000269|PubMed:17267492}.

CC -!- SUBCELLULAR LOCATION: [Non-structural protein 4B]: Host endoplasmic CC reticulum membrane {ECO:0000250|UniProtKB:P17763}; Multi-pass membrane CC protein {ECO:0000250|UniProtKB:P17763}. Note=Located in RE-derived CC vesicles hosting the replication complex. CC {ECO:0000250|UniProtKB:Q9Q6P4}. CC -!- SUBCELLULAR LOCATION: [RNA-directed RNA polymerase NS5]: Host CC endoplasmic reticulum membrane; Peripheral membrane protein; CC Cytoplasmic side. Host nucleus {ECO:0000269|PubMed:16699025}. Host CC cytoplasm {ECO:0000250|UniProtKB:P14335}. Note=Located in RE-associated CC vesicles hosting the replication complex. NS5 protein is mainly CC localized in the nucleus rather than in ER vesicles (By similarity). CC Shuttles between the cytoplasm and nucleus (By similarity). CC {ECO:0000250|UniProtKB:P14335, ECO:0000250|UniProtKB:P17763}. CC -!- DOMAIN: [Small envelope protein M]: The transmembrane domains contain CC an endoplasmic reticulum retention signal. CC {ECO:0000250|UniProtKB:P17763}. CC -!- DOMAIN: [Envelope protein E]: The transmembrane domains contain an CC endoplasmic reticulum retention signal. {ECO:0000250|UniProtKB:P17763}. CC -!- DOMAIN: [RNA-directed RNA polymerase NS5]: Contains a PDZ-binding motif CC that binds to several PDZ-containing cellular proteins. These CC interactions seem necessary for an optimal viral replication. CC {ECO:0000269|PubMed:33547379}. CC -!- PTM: [Genome polyprotein]: Specific enzymatic cleavages in vivo yield CC mature proteins. Cleavages in the lumen of endoplasmic reticulum are CC performed by host signal peptidase, whereas cleavages in the CC cytoplasmic side are performed by serine protease NS3. Signal cleavage CC at the 2K-4B site requires a prior NS3 protease-mediated cleavage at CC the 4A-2K site. {ECO:0000250|UniProtKB:P17763, CC ECO:0000269|PubMed:17067286}. CC -!- PTM: [Protein prM]: Cleaved in post-Golgi vesicles by a host furin, CC releasing the mature small envelope protein M, and peptide pr. This CC cleavage is incomplete as up to 30% of viral particles still carry CC uncleaved prM. {ECO:0000250|UniProtKB:P17763}. CC -!- PTM: [Envelope protein E]: Not N-glycosylated. CC {ECO:0000269|PubMed:2441520}. CC -!- PTM: [Non-structural protein 1]: N-glycosylated.
