Using different structural biology techniques, researchers from EMBL Grenoble's Marcia Group captured a molecular ‘movie’ showing how a large RNA molecule folds and assembles itself.
The findings reveal how RNAs avoid folding errors and evolve into complex cellular machines.
This work paves the way for AI-driven RNA prediction, which could be a step towards an ‘AlphaFold for RNA’.
RNA is a central biological macromolecule, now widely harnessed in medicine and nanotechnology. Like proteins, RNA function often depends on its precise three-dimensional structure. A recent study published in Nature Communications by Marcia group, has captured, for the first time, a ribozyme in
