ArcLight, a popular optogenetic reporter of voltage, is studied at both single-molecule and macroscopic levels, which leads to new mechanistic understanding and to the rational design of a faster reporter.
Single molecule DNA-binding trajectories and deterministic modeling analyses demonstrate a functional role for high energy partly folded states in Transcription Activator-Like Effectors that could improve future TALEN design.
‘Optical tweezers’ measurements of single ribosomes and single mRNA molecules show that the translation rate depends exponentially on the applied force, and suggests that the ribosome functions as a Brownian ratchet.
A general machine learning scheme for integrating time-series data from single-molecule experiments and molecular dynamics simulations is proposed and successfully demonstrated for the folding dynamics of the WW domain.
New insights into the assembly and membrane interactions of the caveolar coat complex reveal the reversible association/dissociation of distinct subcomplexes onto the membrane, which differs from the assembly/disassembly of clathrin-coated pits.
The conformational dynamics of multidrug resistance protein 1 (MRP1) are tracked in real time by single-molecule fluorescence resonance energy transfer experiments, which elucidate the rate-limiting mechanism of MRP1's transport cycle.
Live-cell single-molecule tracking reveals that hierarchical cooperation within the Polycomb Cbx7 protein between the low-affinity H3K27me3-binding module and the high-affinity DNA-binding cassette targets Polycomb repressive complex 1 to chromatin.
