A bipartite sequence motif induces translation reinitiation in feline calicivirus RNA.
The mechanism leading to reinitiation of translation after termination of protein synthesis in eukaryotes has not yet been resolved in detail. One open question concerns the way the post-termination ribosome is tethered to the mRNA to allow binding of the necessary initiation factors. In caliciviruses, a family of positive strand RNA viruses, the capsid protein VP2 is translated via a terminati...
متن کاملIdentification of a protein linked to the genomic and subgenomic mRNAs of feline calicivirus and its role in translation.
125I protein labelling of oligo(dT)-selected RNA from feline calicivirus (FCV)-infected cells revealed that the genomic and 2.4 kb subgenomic RNAs of FCV are linked to a 15 kDa protein (VPg). Proteinase K treatment of FCV RNA, to remove VPg, led to a decrease in the translatability of the RNA, but there was no obvious change in the site of RNA initiation. Addition of the cap analogue 7-methylGT...
متن کاملMonoclonal antibodies to feline calicivirus.
We have prepared monoclonal antibodies to the capsid protein of feline calicivirus (FCV). These antibodies are directed against two close but distinct epitopes, only one of which is involved in virus neutralization. We have used these antibodies and immune cat serum in immunoprecipitation and Western blotting experiments and have identified novel proteins in FCV-infected cells which we term P78...
متن کاملProteinase-polymerase precursor as the active form of feline calicivirus RNA-dependent RNA polymerase.
The objective of this study was to identify the active form of the feline calicivirus (FCV) RNA-dependent RNA polymerase (RdRP). Multiple active forms of the FCV RdRP were identified. The most active enzyme was the full-length proteinase-polymerase (Pro-Pol) precursor protein, corresponding to amino acids 1072 to 1763 of the FCV polyprotein encoded by open reading frame 1 of the genome. Deletio...
متن کاملLeader of the capsid protein in feline calicivirus promotes replication of Norwalk virus in cell culture.
The inability to grow human noroviruses in cell culture has greatly impeded the studies of their pathogenesis and immunity. Vesiviruses, in the family Caliciviridae, grow efficiently in cell culture and encode a unique protein in the subgenomic region designated as leader of the capsid protein (LC). We hypothesized that LC might be associated with the efficient replication of vesiviruses in cel...
