Molecular Biology Customizing MicroRNAs

MicroRNAs (miRNAs) are ubiquitous small noncoding RNAs that regulate gene expression in eukaryotes. Because of the double-stranded nature of intermediates in their synthesis, miRNAs are potential targets for RNA editing. Kawahara et al. now show that members of a related mammalian miRNA cluster are edited in their seed regions, the region that determines their target specificity. The editing, which is tissue specific, changes the potential target range of the miRNAs.
