DOI: 10.1002/bies.202200066

Abstract: Construction of the eukaryotic ribosome is a complex process in which a nascent ribosomal RNA (rRNA) emerging from RNA Polymerase I hierarchically folds into a native three‐dimensional structure. Modular assembly of individual RNA domains through… read more here.

DOI: 10.1016/j.ymeth.2019.05.001

Abstract: We present a 2D replica exchange protocol incorporating secondary structure information to dramatically improve 3D RNA folding using molecular dynamics simulations. We show that incorporating base-pairing restraints into all-atom, explicit solvent simulations enables the accurate… read more here.

DOI: 10.1021/acs.accounts.4c00174

Abstract: Conspectus Creating a living system from nonliving matter is a great challenge in chemistry and biophysics. The early history of life can provide inspiration from the idea of the prebiotic “RNA World” established by ribozymes,… read more here.

DOI: 10.1021/acs.biochem.7b00325

Abstract: RNA folding has been studied extensively in vitro, typically under dilute solution conditions and abiologically high salt concentrations of 1 M Na+ or 10 mM Mg2+. The cellular environment is very different, with 20-40% crowding… read more here.

DOI: 10.1021/acs.biochem.9b00122

Abstract: Noncanonical base pairs play important roles in assembling the three-dimensional structures critical to the diverse functions of RNA. These associations contribute to the looped segments that intersperse the canonical double-helical elements within folded, globular RNA… read more here.

DOI: 10.1021/acs.jctc.1c01233

Abstract: RNA molecules fold as they are transcribed. Cotranscriptional folding of RNA plays a critical role in RNA functions in vivo. Present computational strategies focus on simulations where large structural changes may not be completely sampled.… read more here.

DOI: 10.1038/s41467-024-55601-3

Abstract: Riboswitches are ligand-responsive gene-regulatory RNA elements that perform key roles in maintaining cellular homeostasis. Understanding how riboswitch sensitivity to ligand (EC50) is controlled is critical to explain how highly conserved aptamer domains are deployed in… read more here.

DOI: 10.1080/15476286.2022.2079890

Abstract: ABSTRACT Eukaryotic ribosome biogenesis involves the synthesis of ribosomal RNA (rRNA) and its stepwise folding into the unique structure present in mature ribosomes. rRNA folding starts already co-transcriptionally in the nucleolus and continues when pre-ribosomal… read more here.

DOI: 10.1093/bioinformatics/btad034

Abstract: Background Folding during transcription can have an important influence on the structure and function of ℝNA molecules, as regions closer to the 5’ end can fold into metastable structures before potentially stronger interactions with the… read more here.
