CC -!- FUNCTION: [Polyprotein P1234]: Inactive precursor of the viral
CC replicase, which is activated by cleavages carried out by the viral
CC protease nsP2. {ECO:0000250|UniProtKB:Q8JUX6}.
CC -!- FUNCTION: [Polyprotein P123]: The early replication complex formed by
CC the polyprotein P123 and nsP4 synthesizes the minus-strand RNAs
CC (antigenome) (By similarity). Polyprotein P123 is a short-lived
CC polyprotein that accumulates during early stage of infection
CC (Probable). As soon P123 is cleaved into mature proteins, the plus-
CC strand RNAs synthesis begins (By similarity).
CC {ECO:0000250|UniProtKB:P03317, ECO:0000305}.
CC -!- FUNCTION: [Polyprotein P123']: The early replication complex formed by
CC the polyprotein P123' and nsP4 synthesizes minus-strand RNAs
CC (antigenome) (Probable). Polyprotein P123' is a short-lived polyprotein
CC that accumulates during early stage of infection (Probable). As soon
CC P123' is cleaved into mature proteins, the plus-strand RNAs synthesis
CC begins (Probable). {ECO:0000305}.
CC -!- FUNCTION: [mRNA-capping enzyme nsP1]: Cytoplasmic capping enzyme that
CC catalyzes two virus-specific reactions: methyltransferase and nsP1
CC guanylyltransferase (PubMed:26041283). mRNA-capping is necessary since
CC all viral RNAs are synthesized in the cytoplasm, and host capping
CC enzymes are restricted to the nucleus (Probable). The enzymatic
CC reaction involves a covalent link between 7-methyl-GMP and nsP1,
CC whereas eukaryotic capping enzymes form a covalent complex only with
CC GMP (Probable). NsP1 capping consists in the following reactions: GTP
CC is first methylated into 7-methyl-GMP and then is covalently linked to
CC nsP1 to form the m7GMp-nsP1 complex from which 7-methyl-GMP complex is
CC transferred to the mRNA to create the cap structure (PubMed:26041283).
CC NsP1 is also needed for the initiation of the minus-strand RNAs
CC synthesis (By similarity). Probably serves as a membrane anchor for the
CC replication complex composed of nsP1-nsP4 (By similarity). Nsp1 is
CC needed for the initiation of the minus-strand RNAs synthesis (By
CC similarity). Palmitoylated nsP1 is remodeling host cell cytoskeleton,
CC and induces filopodium-like structure formation at the surface of the
CC host cell (By similarity). {ECO:0000250|UniProtKB:P03317,
CC ECO:0000250|UniProtKB:P08411, ECO:0000250|UniProtKB:Q8JUX6,
CC ECO:0000269|PubMed:26041283, ECO:0000305}.
CC -!- FUNCTION: [Protease nsP2]: Multifunctional protein whose N-terminus is
CC part of the RNA polymerase complex and displays NTPase, RNA
CC triphosphatase and helicase activities (By similarity). NTPase and RNA
CC triphosphatase are involved in viral RNA capping and helicase keeps a
CC check on the dsRNA replication intermediates (By similarity). The C-
CC terminus harbors a protease that specifically cleaves the polyproteins
CC and releases the mature proteins (By similarity). Required for the
CC shutoff of minus-strand RNAs synthesis (By similarity). Inhibits host
CC translation to ensure maximal viral gene expression and evade host
CC immune response (By similarity). {ECO:0000250|UniProtKB:P03317,
CC ECO:0000250|UniProtKB:P08411, ECO:0000250|UniProtKB:P27282,
CC ECO:0000250|UniProtKB:Q8JUX6}.
CC -!- FUNCTION: [Non-structural protein 3]: Seems to be essential for minus-
CC strand RNAs and subgenomic 26S mRNAs synthesis (By similarity).
CC Displays mono-ADP-ribosylhydrolase activity (By similarity). ADP-
CC ribosylation is a post-translational modification that controls various
CC processes of the host cell and the virus probably needs to revert it
CC for optimal viral replication (By similarity). Binds proteins of FXR
CC family and sequesters them into the viral RNA replication complexes
CC thereby inhibiting the formation of host stress granules on viral mRNAs
CC (By similarity). The nsp3-FXR complexes bind viral RNAs and probably
CC orchestrate the assembly of viral replication complexes, thanks to the
CC ability of FXR family members to self-assemble and bind DNA (By
CC similarity). {ECO:0000250|UniProtKB:P03317,
CC ECO:0000250|UniProtKB:P27282}.

CC {ECO:0000250|UniProtKB:P03317, ECO:0000305}.
CC -!- FUNCTION: [RNA-directed RNA polymerase nsP4]: RNA dependent RNA
CC polymerase (By similarity). Replicates genomic and antigenomic RNA by
CC recognizing replications specific signals. The early replication
CC complex formed by the polyprotein P123 and nsP4 synthesizes minus-
CC strand RNAs (By similarity). The late replication complex composed of
CC fully processed nsP1-nsP4 is responsible for the production of genomic
CC and subgenomic plus-strand RNAs (By similarity).

CC -!- DOMAIN: [Protease nsP2]: The N-terminus exhibits NTPase and RNA
CC triphosphatase activities and is proposed to have helicase activity,
CC whereas the C-terminus possesses protease activity (By similarity).
CC Contains a nuclear localization signal and a nuclear export signal,
CC these two motifs are probably involved in the shuttling between the

CC -!- PTM: [Polyprotein P1234]: Specific enzymatic cleavages in vivo yield
CC mature proteins (By similarity). The processing of the polyprotein is
CC temporally regulated (By similarity). In early stages (1.7 hpi), P1234
CC is first cleaved in trans through its nsP2 protease activity, releasing
CC P123' and nsP4, which associate to form the early replication complex
CC (By similarity). At the same time, P1234 is also cut at the nsP1/nsP2
CC site early in infection but with lower efficiency (By similarity).
CC After replication of the viral minus-strand RNAs (4 hpi), the
CC polyproteins are cut at the nsP1/nsP2 and nsP2/nsP3 sites very
CC efficiently, preventing accumulation of P123' and P1234 and allowing
CC the formation of the late replication complex (By similarity).
CC NsP3'/nsP4 site is not cleaved anymore and P34 is produced rather than
CC nsP4 (By similarity). {ECO:0000250|UniProtKB:P03317}.

CC -!- PTM: [RNA-directed RNA polymerase nsP4]: Ubiquitinated; targets the
CC protein for rapid degradation via the ubiquitin system (By similarity).
CC Nsp4 is present in extremely low quantities due to low frequency of
CC translation through the amber stop-codon and the degradation by the
CC ubiquitin pathway (By similarity). {ECO:0000250|UniProtKB:P03317}.
CC -!- MISCELLANEOUS: Viral replication produces dsRNA in the late phase of
CC infection, resulting in a strong activation of host EIF2AK2/PKR,
CC leading to almost complete phosphorylation of EIF2A (By similarity).
CC This inactivates completely cellular translation initiation, resulting
CC shutoff of host proteins synthesis (By similarity). However,
CC phosphorylation of EIF2A is probably not the only mechanism responsible
CC for the host translation shutoff (By similarity). The viral translation
CC can still occur normally because it relies on a hairpin structure in
CC the coding region of sgRNA and is EIF2A-, EIF2D-, EIF4G- EIF4A-
CC independent (By similarity). {ECO:0000250|UniProtKB:P03317}.
CC -!- MISCELLANEOUS: [Polyprotein P1234]: The genome codes for P123, but
CC readthrough of a terminator codon UGA occurs between the codons for
CC Gln-1879 and Arg-1881 giving rise to P1234 (By similarity). P1234 is
CC cleaved quickly by nsP2 into P123' and nsP4 (By similarity). Further
CC processing of p123' gives nsP1, nsP2 and nsP3' which is 6 amino acids
CC longer than nsP3 since the cleavage site is after the readthrough (By
CC similarity). This unusual molecular mechanism ensures that few nsP4 are
CC produced compared to other non-structural proteins (By similarity).
CC Mutant viruses with no alternative termination site grow significantly
CC slower than wild-type virus (By similarity). The opal termination codon
CC is frequently mutated to a sense codon on passage in cell culture (By
CC similarity). The presence of the opal codon may be a requirement for
CC viral maintenance in both vertebrate and invertebrate hosts and a
CC selective advantage may be conferred in cell culture for the sense
CC codon (By similarity). {ECO:0000250|UniProtKB:O90368,
