Protein Class HYDROLASE
Function Replicase polyprotein 1ab: Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein. Host translation inhibitor nsp1: Inhibits host translation by interacting with binds to the host 40S subunit in ribosomal complexes, including the 43S pre-initiation complex and the non-translating 80S ribosome (PubMed:32680882,PubMed:32908316). The C-terminus binds to and obstructs ribosomal mRNA entry tunnel (PubMed:32680882,PubMed:32908316). Thereby inhibits antiviral response triggered by innate immunity or interferons (PubMed:32680882,PubMed:32979938). The nsp1-40S ribosome complex further induces an endonucleolytic cleavage near the 5'UTR of host mRNAs, targeting them for degradation (By similarity). Viral mRNAs less susceptible to nsp1-mediated inhibition of translation, because of their 5'-end leader sequence (PubMed:32908316). By suppressing host gene expression, nsp1 facilitates efficient viral gene expression in infected cells and evasion from host immune response (By similarity). Non-structural protein 2: May play a role in the modulation of host cell survival signaling pathway by interacting with host PHB and PHB2. Indeed, these two proteins play a role in maintaining the functional integrity of the mitochondria and protecting cells from various stresses. Non-structural protein 3: Responsible for the cleavages located at the N-terminus of the replicase polyprotein. Participates together with nsp4 in the assembly of virally-induced cytoplasmic double-membrane vesicles necessary for viral replication (By similarity). Antagonizes innate immune induction of type I interferon by blocking the phosphorylation, dimerization and subsequent nuclear translocation of host IRF3 (PubMed:32733001). Prevents also host NF-kappa-B signaling (By similarity). In addition, PL-PRO possesses a deubiquitinating/deISGylating activity and processes both 'Lys-48'- and 'Lys-63'-linked polyubiquitin chains from cellular substrates (PubMed:32726803). Cleaves preferentially ISG15 from substrates in vitro (PubMed:32726803). Can play a role in host ADP-ribosylation by binding ADP-ribose (PubMed:32578982). Non-structural protein 4: Participates in the assembly of virally-induced cytoplasmic double-membrane vesicles necessary for viral replication. 3C-like proteinase:
