We have obtained the nucleotide sequence of the genomic RNAs of two alphaviruses, Sindbis virus and Middelburg virus, over an extensive region encoding the nonstructural (replicase) proteins. In both viruses in an equivalent position an opal (UGA) termination codon punctuates a long otherwise open reading frame. The nonstructural proteins are translated as polyprotein precursors that are proces...
The cost of damage to the non-structural systems in critical facilities like nuclear power plants and hospitals can exceed 80% of the total cost of damage during an earthquake. The failure of nonstructural components, especially, piping systems led to leakage of water and subsequent shut-down of hospitals immediately after the event. Consequently, the evaluation of performance of these types of...
Although alphaviruses dramatically alter cellular function within hours of infection, interactions between alphaviruses and specific host cellular proteins are poorly understood. Although the alphavirus nonstructural protein 2 (nsP2) is an essential component of the viral replication complex, it also has critical auxiliary functions that determine the outcome of infection in the host. To gain a...
BACKGROUND Replication and assembly of vertebrate reoviruses occur in specific intracellular compartments known as viral factories. Recently, NS88 and NS80, the nonstructural proteins from aquareoviruses, have been proposed to share common traits with µNS from orthoreoviruses, which are involved in the formation of viral factories. METHODOLOGY/PRINCIPAL FINDINGS In this study, the NS80 charac...
We have used immunofluorescent staining and confocal microscopy to examine the subcellular localization of structural and nonstructural bovine papillomavirus (BPV) proteins in cultured cells that produce infectious virions. When expressed separately, L1, the major capsid protein, showed a diffuse nuclear distribution while L2, the minor capsid protein, was found to localize to punctate nuclear ...
Venezuelan equine encephalitis (VEE) virus antigenic subtypes and varieties are considered either epidemic/epizootic or enzootic. In addition to epidemiological differences between the epidemic and enzootic viruses, several in vitro and in vivo laboratory markers distinguishing the viruses have been identified, including differential plaque size, sensitivity to interferon (IFN), and virulence f...
Protein-protein interactions involved in formation of the membrane-associated hepatitis C virus (HCV) replication complex are poorly understood. Here, we investigated nonstructural proteins with deletions in their membrane anchor domains when expressed in the context of the entire HCV polyprotein. Interactions among cytosolic domains of HCV nonstructural proteins were found not to be sufficient...
