Inactive precursor of the viral replicase, which is activated by cleavages carried out by the viral protease nsP2.By similarity
The early replication complex formed by the polyprotein P123 and nsP4 synthesizes the minus-strand RNAs (antigenome) (By similarity). Polyprotein P123 is a short-lived polyprotein that accumulates during early stage of infection (Probable). As soon P123 is cleaved into mature proteins, the plus-strand RNAs synthesis begins (By similarity).By similarityCurated
The early replication complex formed by the polyprotein P123' and nsP4 synthesizes minus-strand RNAs (antigenome) (Probable). Polyprotein P123' is a short-lived polyprotein that accumulates during early stage of infection (Probable). As soon P123' is cleaved into mature proteins, the plus-strand RNAs synthesis begins (Probable).Curated
Cytoplasmic capping enzyme that catalyzes two virus-specific reactions: methyltransferase and nsP1 guanylyltransferase (PubMed:26041283). mRNA-capping is necessary since all viral RNAs are synthesized in the cytoplasm, and host capping enzymes are restricted to the nucleus (Probable). The enzymatic reaction involves a covalent link between 7-methyl-GMP and nsP1, whereas eukaryotic capping enzymes form a covalent complex only with GMP (By similarity). NsP1 capping consists in the following reactions: GTP is first methylated into 7-methyl-GMP and then is covalently linked to nsP1 to form the m7GMp-nsP1 complex from which 7-methyl-GMP complex is transferred to the mRNA to create the cap structure (PubMed:26041283). NsP1 is also needed for the initiation of the minus-strand RNAs synthesis (By similarity). Probably serves as a membrane anchor for the replication complex composed of nsP1-nsP4 (By similarity). Nsp1 is needed for the initiation of the minus-strand RNAs synthesis (By similarity). Palmitoylated nsP1 is remodeling host cell cytoskeleton, and induces filopodium-like structure formation at the surface of the host cell (By similarity).By similarityCurated1 Publication
Multifunctional protein whose N-terminus is part of the RNA polymerase complex and displays NTPase, RNA triphosphatase and helicase activities (By similarity). NTPase and RNA triphosphatase are involved in viral RNA capping and helicase keeps a check on the dsRNA replication intermediates (By similarity). The C-terminus harbors a protease that specifically cleaves the polyproteins and releases the mature proteins (By similarity). Required for the shutoff of minus-strand RNAs synthesis (By similarity). Inhibits host translation to ensure maximal viral gene expression and evade host immune response (PubMed:27318152).By similarity1 Publication
Seems to be essential for minus-strand RNAs and subgenomic 26S mRNAs synthesis (By similarity). Displays mono-ADP-ribosylhydrolase activity (PubMed:28150709, PubMed:27440879). ADP-ribosylation is a post-translational modification that controls various processes of the host cell and the virus probably needs to revert it for optimal viral replication (PubMed:28150709). Binds proteins of FXR family and sequesters them into the viral RNA replication complexes thereby inhibiting the formation of host stress granules on viral mRNAs (PubMed:27509095). The nsp3-FXR complexes bind viral RNAs and probably orchestrate the assembly of viral replication complexes, thanks to the ability of FXR family members to self-assemble and bind DNA (PubMed:27509095).By similarity3 Publications

RNA dependent RNA polymerase (By similarity). Replicates genomic and antigenomic RNA by recognizing replications specific signals. The early replication complex formed by the polyproteins P123/P123' and nsP4 synthesizes minus-strand RNAs (By similarity). The late replication complex composed of fully processed nsP1-nsP4 is responsible for the production of genomic and subgenomic plus-strand RNAs (By similarity).By similarity

Miscellaneous

Viral replication produces dsRNA in the late phase of infection, resulting in a strong activation of host EIF2AK2/PKR, leading to almost complete phosphorylation of EIF2A (By similarity). This inactivates completely cellular translation initiation, resulting shutoff of host proteins synthesis (By similarity). However, phosphorylation of EIF2A is probably not the only mechanism responsible for the host translation shutoff (By similarity). The viral translation can still occur normally because it relies on a hairpin structure in the coding region of sgRNA and is EIF2A-, EIF2D-, EIF4G- EIF4A-independent (By similarity).By similarity
The genome codes for P123, but readthrough of a terminator codon UGA occurs between the codons for Gln-1879 and Arg-1881 giving rise to P1234 (By similarity). P1234 is cleaved quickly by nsP2 into P123' and nsP4 (By similarity). Further processing of p123' gives nsP1, nsP2 and nsP3' which is 6 amino acids longer than nsP3 since the cleavage site is after the readthrough (By similarity). This unusual molecular mechanism ensures that few nsP4 are produced compared to other non-structural proteins (By similarity). Mutant viruses with no alternative termination site grow significantly slower than wild-type virus (By similarity). The opal termination codon is frequently mutated to a sense codon on passage in cell culture (By similarity). The presence of the opal codon may be a requirement for viral maintenance in both vertebrate and invertebrate hosts and a selective advantage may be conferred in cell culture for the sense codon (By similarity).By similarity

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

    The N-terminus exhibits NTPase and RNA triphosphatase activities and is proposed to have helicase activity, whereas the C-terminus possesses protease activity (By similarity). Contains a nuclear localization signal and a nuclear export signal, these two motifs are probably involved in the shuttling between the cytoplasm and the nucleus of nsP2 (PubMed:17652399).By similarity1 Publication
    In the N-terminus, the macro domain displays a mono-ADP-ribosylhydrolase activity (PubMed:28150709, PubMed:27440879). The central part has a zinc-binding function (By similarity). The C-terminus contains two approximate repeats necessary and sufficient for formation of the nsP3/FXR complex (PubMed:27509095).By similarity3 Publications

    <p>This subsection of the 'Entry information' section provides one or more accession number(s). These are stable identifiers and should be used to cite UniProtKB entries. Upon integration into UniProtKB, each entry is assigned a unique accession number, which is called 'Primary (citable) accession number'.<p><a href='/help/accession_numbers' target='_top'>More...</a></p>AccessioniPrimary (citable) accession number: P27282
