RNAs are flexible molecules involved in a multitude of roles in the cell. Specifically, noncoding RNAs (i.e., RNAs that do not encode a protein) have important functions in the regulation of biological processes such as RNA decay, translation, or protein translocation. In bacteria, most of those noncoding RNAs have been shown to be critical for posttranscriptional control through their binding to the untranslated regions of target mRNAs. Recent evidence shows that some of these noncoding RNAs have the propensity to self-assemble in prokaryotes. Although the function of this self-assembly is not known and may vary from one RNA to another, it offers new insights into riboregulation pathways. We present here the various approaches that can be used for the detection and analysis of bacterial small noncoding RNA self-assemblies.
