Hypothesis
RNA folding is governed by the local balance between destabilizing loops and their stabilizing adjacent stems.
Conclusion
The study establishes local stability compensation as a fundamental principle that could improve the design of functional RNAs.
Supporting Evidence
- Analysis of over 100,000 RNA structures revealed pronounced LSC signatures in bulges and adjacent stems.
- Distinct patterns of LSC were observed across different RNA families that align with their biological functions.
- Stem reactivity correlates strongly with LSC, with R² = 0.458 for hairpin loops.
Takeaway
RNA is like a puzzle, and this study shows that the pieces fit together better when we look closely at how they connect, rather than just the whole picture.
Methodology
The study analyzed over 100,000 RNA structures and validated findings through DMS chemical mapping of RNA variants.
