Article Title: RNase III-independent microRNA biogenesis in mammalian cells
Abstract: RNase III enzymes are fundamental to the biogenesis of microRNAs (miRNAs) and small interfering RNAs (siRNAs) in all species studied. Although alternative miRNA pathways independent of Drosha or Dicer exist, each still requires one RNase III-type enzyme. Here, we describe two strategies that marry either RNase Z or the Integrator complex with the slicing activity of Argonaute2 to generate highly functional mature miRNAs. We provide stringent validation of their RNase III independence by demonstrating efficient miRNA biogenesis and activity in Drosha and Dicer knockout cells. These data provide proof-of-principle evidence for additional mechanistic possibilities for efficient generation of small regulatory RNAs, and represent novel silencing triggers that may be exploited for technical purposes.
