The Kinesin Speed Paradox Revisited: How Can Cargoes Move Faster Than Their Motors?

Cytoskeleton, EarlyView.
ABSTRACT Intracellular transport is essential for cellular organization and function. Kinesin‐1, the founding member of the kinesin superfamily, delivers a wide range of cargoes along microtubules. Since its discovery, extensive work has identified cargo–kinesin interactions and regulatory mechanisms.

Distinct Conformational Switches Control WPD‐Loop Dynamics Across Protein Tyrosine Phosphatase Subfamilies

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Protein Tyrosine Phosphatases (PTPs) regulate cellular signaling by balancing phosphotyrosine levels through a conserved WPD‐loop that switches between open (inactive) and closed (active) conformations. While this conformational change is crucial for catalysis, the structural factors governing this motion remain poorly understood.

Unexpected Effects of Macromolecular Crowding on Protein Stability

, 2016
Most theories about macromolecular crowding focus on two ideas: the macromolecular nature of the crowder and entropy. For proteins, the volume excluded by the crowder favors compact native states over expanded denatured states, enhancing protein ...

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

An optimized strategy to measure protein stability highlights differences between cold and hot unfolded states

Nature Communications, 2017
Crowding effects—important when considering cellular environments—greatly influence protein stability. Here the authors study the impact of macromolecular crowders on high and low temperature protein unfolding, and show that volume exclusion effects are ...

Symmetry‐Guided Optical Control of Dynamic 1D Protein Self‐Assembly and Precise In Vitro Initiation of Biomolecular Condensation

Small, EarlyView.
A photoreversible 1D protein assembly has been developed by utilizing symmetry matching between StrepTactin and photoswitchable Dronpa145N. The light‐induced modulation of oligomerization allows for precise control over protein connectivity and valency.

Deciphering Molecular Charge Anisotropy: The Case of Antibody Solutions

Small, EarlyView.
Molecular charge anisotropy emerges as a key determinant of antibody solution behavior. A multiscale framework combining electrostatic mapping, coarse‐grained simulations, and machine‐learning‐assisted optimization identifies charge patterns that reproduce experimental structure factors and predict collective properties across concentration, revealing ...

Exploiting Phase Partitioning of a Giant Trimeric Fibrous Protein Scaffold to Potentiate Chitinase‐Driven Antifungal Activity

Small, EarlyView.
Cstalk, a giant fibrous protein, selectively partitions into the dextran‐rich phase in polyethylene glycol/dextran aqueous two‐phase systems, functioning as a recruiter for proteins of interest. This phase‐selective recruitment can be extended to fungal cell walls, enabling the targeted localization of enzymes and enhancing antifungal activity through ...
