Yellow fever virus capsid protein is a potent suppressor of RNA silencing that binds double-stranded RNA.
Mosquito-borne flaviviruses, including yellow fever virus (YFV), Zika virus (ZIKV), and West Nile virus (WNV), profoundly affect human health. The successful transmission of these viruses to a human host depends on the pathogen's ability to overcome a potentially sterilizing immune response in the vector mosquito. Similar to other invertebrate animals and plants, the mosquito's RNA silencing pa...
متن کاملIdentification of an RNA silencing suppressor from a plant double-stranded RNA virus.
RNA silencing is a mechanism which higher plants and animals have evolved to defend against viral infection in addition to regulation of gene expression for growth and development. As a counterdefense, many plant and some animal viruses studied to date encode RNA silencing suppressors (RSS) that interfere with various steps of the silencing pathway. In this study, we report the first identifica...
متن کاملThe core of bluetongue virus binds double-stranded RNA.
Double-stranded RNA (dsRNA) viruses conceal their genome from the host to avoid triggering unfavorable cellular responses. The crystal structure of the core of one such virus, bluetongue virus, reveals an outer surface festooned with dsRNA. This may represent a deliberate strategy to sequester dsRNA released from damaged particles to prevent host cell shutoff.
متن کاملTwo classes of short interfering RNA in RNA silencing.
RNA silencing is a eukaryotic genome defence system that involves processing of double-stranded RNA (dsRNA) into 21-26 nt, short interfering RNA (siRNA). The siRNA mediates suppression of genes corresponding to the dsRNA through targeted RNA degradation. In some plant systems there are additional silencing processes, involving systemic spread of silencing and RNA-directed methylation/transcript...
متن کاملJoining of long double-stranded RNA molecules through controlled overhangs.
We describe two methods for creating long (>1 kb) dsRNA molecules with specific, user-controlled overhangs for efficient hybridization and ligation. The two methods create double-stranded RNA (dsRNA) molecules with 5' overhangs or with 3' overhangs using T7 RNA polymerase (T7 RNAP) in transcription reactions of carefully designed PCR products. Primers utilized in the PCR reactions provide the t...
