RNA nanotechnology often involves protein–RNA complexes that require significant understanding of how the proteins and RNAs contact each other. The CLIP-Seq (cross-linking immunoprecipitation, and DNA sequencing) protocol can be used to probe the RNA molecules that interact with proteins. We have optimized the procedures for RNA fragmentation, immunoprecipitation, and library construction in CLIPSeq to map the interactions between the RNA and the capsid of a simple positive-strand RNA virus. The results show that distinct portions of the viral RNA contact the capsid. The protocol should be applicable to other RNA virions and also RNA–protein nanoparticles.
