Ribosomal protein S6 associates with alphavirus nonstructural protein 2 and mediates expression from alphavirus messages.
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...
متن کاملNonstructural Proteins of Alphavirus—Potential Targets for Drug Development
Alphaviruses are enveloped, positive single-stranded RNA viruses, typically transmitted by arthropods. They often cause arthralgia or encephalitic diseases in infected humans and there is currently no targeted antiviral treatment available. The re-emergence of alphaviruses in Asia, Europe, and the Americas over the last decade, including chikungunya and o'nyong'nyong viruses, have intensified t...
متن کاملSequence coding for the alphavirus nonstructural proteins is interrupted by an opal termination codon.
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...
متن کاملInteraction of hepatitis C virus nonstructural protein 5A with core protein is critical for the production of infectious virus particles.
Nonstructural protein 5A (NS5A) of the hepatitis C virus (HCV) possesses multiple and diverse functions in RNA replication, interferon resistance, and viral pathogenesis. Recent studies suggest that NS5A is involved in the assembly and maturation of infectious viral particles; however, precisely how NS5A participates in virus production has not been fully elucidated. In the present study, we de...
متن کاملCorrection: MAVS Protein Is Attenuated by Rotavirus Nonstructural Protein 1
Rotavirus is the single, most important agent of infantile gastroenteritis in many animal species, including humans. In developing countries, rotavirus infection attributes approximately 500,000 deaths annually. Like other viruses it establishes an intimate and complex interaction with the host cell to counteract the antiviral responses elicited by the cell. Among various pattern recognition re...
