Fly Antiviral RNA Silencing and miRNA Biogenesis Claim ARS2

Abstract

In plants and invertebrates, small silencing RNAs function in antiviral defense and developmental patterning through pathways that were so far considered genetically distinct. In a recent issue of Cell, Sabin and colleagues report the identification of Drosophila Ars2, a protein required for both these small RNA-mediated functions. © 2009 Elsevier Inc. All rights reserved.
