The Making of an siRNA
Abstract
An array of gene silencing pathways share a common early step: Dicer cleaves double-stranded RNA (dsRNA) into approximately 20-25 nucleotide fragments that direct the silencing machinery to specific targets. A recent report in Cell reveals how Dicer's two RNase III domains collaborate during dsRNA processing and sets the stage for a deeper understanding of Dicer's roles in later phases of silencing complex assembly.
