Coupled RNA processing and transcription of intergenic primary microRNAs.
The first step in microRNA (miRNA) biogenesis occurs in the nucleus and is mediated by the Microprocessor complex containing the RNase III-like enzyme Drosha and its cofactor DGCR8. Here we show that the 5'-->3' exonuclease Xrn2 associates with independently transcribed miRNAs and,...
