摘要
The discovery of microRNAs (miRNAs) has changed the paradigm of gene regulation, leaving us with numerous exciting questions regarding what these molecules do and how they originate. A model for miRNA biogenesis has emerged recently, yet several key factors - including the identity of the miRNA nuclear export receptor remained unknown. However, recent studies have shown that exportin-5 (Exp5), a Ran-dependent importin-p-related transport receptor, mediates nuclear export of miRNA precursors (pre-miRNAs).
