Targeting of Dicer-2 and RNA by a Viral RNA Silencing Suppressor in Drosophila Cells

Abstract excerpt

RNA interference (RNAi) is a eukaryotic gene-silencing mechanism that functions in antiviral immunity in diverse organisms. To combat RNAi-mediated immunity, viruses encode viral suppressors of RNA silencing (VSRs) that target RNA and protein components in the RNAi machinery. Although the endonuclease Dicer plays key roles in RNAi immunity, little is known about how VSRs target Dicer. Here, we show that the B2...
