SH3 Domain-Mediated Recruitment of Host Cell Amphiphysins by Alphavirus nsP3 Promotes Viral RNA Replication
Among the four non-structural proteins of alphaviruses the function of nsP3 is the least well understood. NsP3 is a component of the viral replication complex, and composed of a conserved aminoterminal macro domain implicated in viral RNA synthesis, and a poorly conserved carboxyterminal region. Despite the lack of overall homology we noted a carboxyterminal proline-rich sequence motif shared b...
متن کاملRequirements for assembly of poliovirus replication complexes and negative-strand RNA synthesis.
HeLa cells were transfected with several plasmids that encoded all poliovirus (PV) nonstructural proteins. Viral RNAs were transcribed by T7 RNA polymerase expressed from recombinant vaccinia virus. All plasmids produced similar amounts of viral proteins that were processed identically; however, RNAs were designed either to serve as templates for replication or to contain mutations predicted to...
متن کاملSeeking Membranes: Positive-Strand RNA Virus Replication Complexes
Viruses containing RNA genomes, or RNA viruses, constitute an extensive genetic group of plant, animal, and human viruses. RNA viruses include many viruses that are important human pathogens, and have been shown to have the ability to move from animals to humans, resulting in zoonotic-human epidemics. RNA viruses that contain single-stranded RNA genomes of positive polarity are known as positiv...
متن کاملRNA Virus Replication Complexes
The majority of viruses infecting animals and plants today are RNA viruses [1]. There are double-stranded (ds) RNA viruses with dsRNA genomes, as well as (+) and (2)RNA viruses whose genomes are single-stranded (ss) RNA of either positive or negative polarity. RNA viruses have small genomes that rarely exceed 30 kb in size, and a large portion of their genomes is used to encode proteins involve...
متن کاملStructure, function and intracellular dynamics of alphavirus replication complexes
Intracellular membrane alterations are hallmarks of positive-sense RNA (+RNA) virus replication. Strong evidence indicates that within these ‘exotic’ compartments, viral replicase proteins engage in RNA genome replication and transcription. To date, fundamental questions such as the origin of altered membranes, mechanisms of membrane deformation and topological distribution and function of vira...
