[Isoform Replicase polyprotein 1a]: Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein. {Curator Inference}. [Host translation inhibitor nsp1]: Inhibits host translation by interacting with the 40S ribosomal subunit. The nsp1-40S ribosome complex further induces an endonucleolytic cleavage near the 5'UTR of host mRNAs, targeting them for degradation. Viral mRNAs are not susceptible to nsp1-mediated endonucleolytic RNA cleavage thanks to the presence of a 5'-end leader sequence and are therefore protected from degradation. By suppressing host gene expression, nsp1 facilitates efficient viral gene expression in infected cells and evasion from host immune response (PubMed:23035226). May disrupt nuclear pore function by binding and displacing host NUP93 (PubMed:30943371). {Experimental EvidencePubMed:23035226, Experimental EvidencePubMed:30943371}. [Non-structural protein 2]: May play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2 (PubMed:19640993). Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses (PubMed:19640993). {Experimental EvidencePubMed:19640993}. [Papain-like protease nsp3]: Responsible for the cleavages located at the N-terminus of the replicase polyprotein. In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates (PubMed:17692280). Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (PubMed:23943763). Nsp3, nsp4 and nsp6 together are sufficient to form DMV (PubMed:24410069, PubMed:23943763). Antagonizes innate immune induction of type I interferon by blocking the phosphorylation, dimerization and subsequent nuclear translocation of host IRF3 (PubMed:19369340, PubMed:24622840). Prevents also host NF-kappa-B signaling (PubMed:19369340, PubMed:24622840). {Experimental EvidencePubMed:16271890, Experimental EvidencePubMed:17692280, Experimental EvidencePubMed:19369340, Experimental EvidencePubMed:23943763, Experimental EvidencePubMed:24622840, Curator InferencePubMed:24410069}. [Non-structural protein 4]: Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (PubMed:23943763, PubMed:24410069). Alone appears incapable to induce membrane curvature, but together with nsp3 is able to induce paired membranes (PubMed:23943763). Nsp3, nsp4 and nsp6 together are sufficient to form DMV (PubMed:23943763, PubMed:24410069). {Experimental EvidencePubMed:23943763, Curator InferencePubMed:24410069}. [3C-like proteinase nsp5]: Cleaves the C-terminus of replicase polyprotein at 11 sites. Recognizes substrates containing the core sequence [ILMVF]-Q-|-[SGACN]. Also able to bind an ADP-ribose-1''- phosphate (ADRP). May cleave host ATP6V1G1 thereby modifying host vacuoles intracellular pH. {Sequence AnalysisPROSITE-ProRule:PRU00772, Experimental EvidencePubMed:16226257}. [Non-structural protein 6]: Plays a role in host membrane rearrangement that leads to creation of cytoplasmic double-membrane vesicles (DMV) necessary for viral replication (PubMed:23943763). Nsp3, nsp4 and nsp6 together are sufficient to form DMV (PubMed:23943763, PubMed:24410069). Plays a role in the initial induction of autophagosomes from host reticulum endoplasmic. Later, limits the expansion of these phagosomes that are no longer able to deliver viral components to lysosomes (PubMed:24991833). {Experimental EvidencePubMed:23943763, Experimental EvidencePubMed:24991833, Curator InferencePubMed:24410069}. [Non-structural protein 7]: Forms a hexadecamer with nsp8 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. {ECO:0000269|PubMed:22039154}. [Non-structural protein 8]: Forms a hexadecamer with nsp7 (8 subunits of each) that may participate in viral replication by acting as a primase. Alternatively, may synthesize substantially longer products than oligonucleotide primers. {ECO:0000269|PubMed:22039154}. [Non-structural protein 9]: Plays an essential role in viral replication by forming a homodimer that binds single-stranded RNA. {ECO:0000269|PubMed:19153232}. [Non-structural protein 10]: Plays a pivotal role in viral transcription by stimulating both nsp14 3'-5' exoribonuclease and nsp16 2'-O-methyltransferase activities. Therefore plays an essential role in viral mRNAs cap methylation. {ECO:0000269|PubMed:22635272}. | Assigned Ontology terms |
