P123 and P123' are short-lived polyproteins, accumulating during early stage of infection. P123 is directly translated from the genome, whereas P123' is a product of the cleavage of P1234. They localize the viral replication complex to the cytoplasmic surface of modified endosomes and lysosomes. By interacting with nsP4, they start viral genome replication into antigenome. After these early events, P123 and P123' are cleaved sequentially into nsP1, nsP2 and nsP3/nsP3'. This sequence of delayed processing would allow correct assembly and membrane association of the RNA polymerase complex (By similarity).By similarity
nsP1 is a cytoplasmic capping enzyme. This function is necessary since all viral RNAs are synthesized in the cytoplasm, and host capping enzymes are restricted to the nucleus. The enzymatic reaction involves a covalent link between 7-methyl-GMP and nsP1, whereas eukaryotic capping enzymes form a covalent complex only with GMP. nsP1 capping would consist in the following reactions: GTP is first methylated and then forms the m7GMp-nsP1 complex, from which 7-methyl-GMP complex is transferred to the mRNA to create the cap structure. Palmitoylated nsP1 is remodeling host cell cytoskeleton, and induces filopodium-like structure formation at the surface of the host cell (By similarity).By similarity
nsP2 has two separate domain with different biological activities. The N-terminal section is part of the RNA polymerase complex and has RNA trisphosphatase and RNA helicase activity. The C-terminal section harbors a protease that specifically cleaves and releases the four mature proteins. Also inhibits cellular transcription by inducing rapid degradation of POLR2A, a catalytic subunit of the RNAPII complex. The resulting inhibition of cellular protein synthesis serves to ensure maximal viral gene expression and to evade host immune response (By similarity).By similarity
nsP3 and nsP3' are essential for minus strand and subgenomic 26S mRNA synthesis.By similarity
nsP4 is an RNA dependent RNA polymerase. It replicates genomic and antigenomic RNA by recognizing replications specific signals. Transcribes also a 26S subgenomic mRNA by initiating RNA synthesis internally on antigenomic RNA. This 26S mRNA codes for structural proteins. nsP4 is a short-lived protein regulated by several ways: the opal codon readthrough and degradation by ubiquitin pathway (By similarity).By similarity

Miscellaneous

The genome codes for P123, but readthrough of a terminator codon UGA occurs between the codons for Glu-1794 and Leu-1795. This readthrough produces P1234, cleaved quickly by nsP2 into P123' and nsP4. 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. This unusual molecular mechanism ensures that few nsP4 are produced compared to other non-structural proteins. Mutant viruses with no alternative termination site grow significantly slower than wild-type virus.

Specific enzymatic cleavages in vivo yield mature proteins. The polyprotein is synthesized as P123, or P1234 by stop codon readthrough. These polyproteins are processed differently depending on the stage of infection. In early stages, P1234 is first cleaved in trans, through its nsP2 protease activity, releasing P123' and nsP4. P123/P123' and nsP4 start to replicate the viral genome into its antigenome. After these early events, nsP1 is cleaved in cis by nsP2 protease, releasing the P23/P23' polyprotein. Cleavage of nsP1 exposes an 'activator' at the N-terminus of P23/P23' which induces its cleavage into nsP2 and nsP3 by the viral protease. This sequence of delayed processing would allow correct assembly and membrane association of the RNA-polymerase complex. In the late stage of infection, the presence of free nsP2 in the cytoplasm cleaves P1234 quickly into P12 and P34, then into the four nsP.

nsP4 is ubiquitinated; targets the protein for rapid degradation via the ubiquitin system.By similarity

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. This inactivates completely cellular translation initiation, resulting in a dramatic shutoff of proteins synthesis. Translation of viral non-structural polyprotein and all cellular proteins are stopped in infected cell between 2 and 4 hours post infection. Only the 26S mRNA is still translated into viral structural proteins, presumably through a unique mechanism of enhancer element which counteract the translation inhibition mediated by EIF2A. By doing this, the virus uses the cellular defense for its own advantage: shutoff of cellular translation allows to produce big amounts of structural proteins needed for the virus to bud out of the doomed cell.

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:iB15A37394D0715A5
