Abstract

Partin et al. present cryo-EM structures of the Microprocessor complex bound to a pri-miRNA, revealing how Drosha and DGCR8 recognize substrates and determine cleavage sites. Two dsRBDs form a molecular ruler to measure the stem length, and “Belt” and “Wedge” in Drosha play key roles in detecting the basal junction.
