Alternative miRNA biogenesis pathways and the interpretation of core miRNA pathway mutants.

Abstract excerpt

Since the establishment of a canonical animal microRNA biogenesis pathway driven by the RNase III enzymes Drosha and Dicer, an unexpected variety of alternative mechanisms that generate functional microRNAs have emerged. We review here the many Drosha-independent and Dicer-independent microRNA biogenesis strategies characterized over the past few years. Beyond reflecting the flexibility of small RNA machineries,...
