Nonstructural 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 کاملRibosomal 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 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 کاملSequential translation of nonstructural proteins in cells infected with a Semliki Forest virus mutant.
Four nonstructural proteins with apparent molecular weights of 70,000 (ns-70), 86,000 (ns-86), 78,000 (ns-78), and 60,000 (ns-60) were translated in cells infected with Semliki Forest virus ts-1 mutant and maintained at the restrictive temperature. After synchronization of the initiation of protein synthesis these proteins were synthesized in the above order, suggesting that they are translated...
متن کاملAlphavirus Restriction by IFITM Proteins
Interferon inducible transmembrane proteins (IFITMs) are broad-spectrum antiviral factors. In cell culture the entry of many enveloped viruses, including orthomyxo-, flavi-, and filoviruses, is inhibited by IFITMs, though the mechanism(s) involved remain unclear and may vary between viruses. We demonstrate that Sindbis and Semliki Forest virus (SFV), which both use endocytosis and acid-induced ...
