RNAi: The Nuts and Bolts of the RISC Machine

Research on RNA interference and microRNA pathways continues to accelerate. Combinations of biochemical, genetic, and structural approaches are providing new insights into the mechanism by which small, approximately 21 nt long RNAs find their way into the RISC effector complexes and how the RISCs execute their mission of RNA-guided posttranscriptional gene silencing.
