Insights into eukaryotic, bacterial and archaeal RNA-based regulatory systems, including microRNAs, small interfering RNAs, clustered regularly interspaced short palindromic repeats (CRISPR) RNA and small RNAs that are dependent on the RNA chaperone protein Hfq, have revealed that they achieve specificity using similar strategies. Specifically, the presentation of short 'seed sequences' within a ribonucleoprotein complex facilitates the search for and recognition of targets.
