Single-molecule FRET uncovers hidden conformations and dynamics of human Argonaute 2

open access: yesNature Communications, 2022
Single-molecule FRET measurements provide detailed insights into the conformational states and dynamics of human Argonaute 2 that are required for its function at the core of the eukaryotic RNA silencing pathway.

Single‐molecule genomics [PDF]

open access: yesThe Journal of Pathology, 2009
AbstractThe term ‘single‐molecule genomics’ (SMG) describes a group of molecular methods in which single molecules are detected or sequenced. The focus on the analysis of individual molecules distinguishes these techniques from more traditional methods, in which template DNA is cloned or PCR‐amplified prior to analysis. Although technically challenging,

Pathological mutations differentially affect the self-assembly and polymerisation of the innate immune system signalling adaptor molecule MyD88

open access: yesBMC Biology, 2018
Background Higher-order self-assembly of proteins, or “prion-like” polymerisation, is now emerging as a simple and robust mechanism for signal amplification, in particular within the innate immune system, where the recognition of pathogens or danger ...

Spontaneous Confinement of mRNA Molecules at Biomolecular Condensate Boundaries

open access: yesCells, 2023
Cellular biomolecular condensates, termed ribonucleoprotein (RNP) granules, are often enriched in messenger RNA (mRNA) molecules relative to the surrounding cytoplasm.

Force transmission by retrograde actin flow-induced dynamic molecular stretching of Talin

open access: yesNature Communications, 2023
Force transmission at integrin-based adhesions is important for cell migration and mechanosensing. Talin is an essential focal adhesion (FA) protein that links F-actin to integrins.

Single Molecule Nanometronome [PDF]

open access: yesNano Letters, 2006
We constructed a DNA-based nanomechanical device called the nanometronome. Our device is made by introducing complementary single-stranded overhangs at the two arms of the DNA four-way junction. The ticking rates of this stochastic metronome depend on ion concentrations and can be changed by a set of DNA-based switches to deactivate/reactivate the ...

Single-Molecule Reaction-Diffusion

open access: yesBiophysical Journal, 2023
AbstractWe propose to capture reaction-diffusion on a molecule-by-molecule basis from the fastest acquirable timescale, namely individual photon arrivals. We illustrate our method on intrinsically disordered human proteins, the linker histone H1.0 as well as its chaperone prothymosinα, as these diffuse through an illuminated confocal spot and interact ...

A mechanism with severing near barbed ends and annealing explains structure and dynamics of dendritic actin networks

open access: yeseLife, 2022
Single molecule imaging has shown that part of actin disassembles within a few seconds after incorporation into the dendritic filament network in lamellipodia, suggestive of frequent destabilization near barbed ends.

Direct-laser writing for subnanometer focusing and single-molecule imaging

open access: yesNature Communications, 2022
Focus-locking improves localization precision in single-molecule microscopy, but fiducials are often deposited at random and provide limited 3D compensation.

The Shine-Dalgarno sequence of riboswitch-regulated single mRNAs shows ligand-dependent accessibility bursts

open access: yesNature Communications, 2016
In response to intracellular signals, bacterial translational riboswitches embedded in mRNAs can regulate gene expression through inhibition of translation initiation.
