Significance The steady-state levels of miRNAs are under sophisticated control to ensure their proper functions such as development and responses to environmental stimuli. Nevertheless, enzymes responsible for the degradation of various forms of unmethylated miRNAs remain enigmatic, which largely impedes our understanding of miRNA homeostasis and active turnover. Here we report a 3′ to 5′ exoribonuclease Atrimmer 2 that may degrade unmethylated miRNAs in their miRNA/miRNA* duplex status, at… Expand
