Lipid vesicles chaperone an encapsulated RNA aptamer
So far little is known about how encapsulation affects the activity and folding of RNA, which is of interest for understanding the origin of cellular life.

RNAs are surprisingly adept at folding into specific shapes capable of ligand recognition and catalysis. Thermodynamic analysis of the unfolding of several different RNAs suggests that there are at least three strategies an RNA might use to achieve a very stable and compactly folded structure: hydrogen bonding between irregular complementary surfaces ...

We study RNA foldings and investigate their topology using a combination of knot theory and embedded rigid vertex graphs. Knot theory has been helpful in modeling biomolecules, but classical knots place emphasis on a biomolecule's entanglement while ignoring their intrachain interactions.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Metal-ion binding and metal-ion induced folding of the adenine-sensing riboswitch aptamer domain
Divalent cations are important in the folding and stabilization of complex RNA structures. The adenine-sensing riboswitch controls the expression of mRNAs for proteins involved in purine metabolism by directly sensing intracellular adenine levels ...

Mapping the kinetic barriers of a Large RNA molecule's folding landscape.
The folding of linear polymers into discrete three-dimensional structures is often required for biological function. The formation of long-lived intermediates is a hallmark of the folding of large RNA molecules due to the ruggedness of their energy ...

Vfold: a web server for RNA structure and folding thermodynamics prediction. [PDF]
The ever increasing discovery of non-coding RNAs leads to unprecedented demand for the accurate modeling of RNA folding, including the predictions of two-dimensional (base pair) and three-dimensional all-atom structures and folding stabilities.

Probing RNA Folding Pathways by RNA Fingerprinting [PDF]
AbstractThis unit provides protocols for using native polyacrylamide gel electrophoresis to distinguish folding and unfolding conformers of RNA. It is useful for studying conformers that can exchange in a period of minutes or seconds, and that are thus difficult to study by solution‐based methods.
