However, RNA quaternary structures have been rarely reported. Comparative genomics analysis has identified RNA families containing hundreds of sequences that adopt conserved secondary structures and likely fold into complex three-dimensional (3D) structures. We use cryo-electron microscopy (cryo-EM) to determine structures from four RNA families, including ARRPOF and OLE forming dimers, and ROOL and GOLLD forming hexameric, octameric and dodecameric nanostructures, at 2.6 to 4.6 Å resolutions. These homo-oligomeric assemblies reveal a plethora of structural motifs that contribute to RNA multivalency, including kissing loop, palindromic base-pairing, A-stacking, metal ion coordination, pseudoknot and minor-groove interactions. These results provide the molecular basis of intermolecular interactions driving RNA multivalency with potential functional relevance.
