Competition between the antagonistic motor proteins myosin V and myosin VI finely tunes unidirectional transport of cargo on different actin architectures.
The flexible network architecture of the brain is sensitive to the modulation of neural gain, which may be mediated by ascending arousal nuclei, such as the noradrenergic locus coeruleus.
A biophysically principled algorithm can build quantitative models of protein-DNA binding specificity of unprecedented accuracy from a leading type of high-throughput in vitro binding data.
Methylation specifically enhances the ability of hopanoids to rigidify membranes under physiologically relevant conditions, which impacts the current interpretation of the 2-methylhopane fossil record.
Imaging experiments and simulations reveal that the biophysical mechanism for force generation needed to engulf a forespore is based on coordinated cell wall synthesis and degradation.
Challenging a widespread model, biophysical and electrophysiological experiments suggest a new mechanism whereby complexins inhibit neurotransmitter release through electrostatic repulsion between their accessory helix and the membranes.
Diverse biophysical properties of β1 and β3 integrin transmembrane and cytoplasmic domains result in distinct mechanisms of integrin activation and function.
New biophysical methods and analyses visualize in real-time a chain of coordinated single-molecular events on a living cell, enabling the inner workings of a mechanoreceptor important to biology to be elucidated.
Modeling and biophysics show that the unstructured acidic tail of the Sm protein Hfq mimics nucleic acid to auto inhibit its chaperone activity, preventing Hfq from being sequestered by inauthentic substrates and providing insight into the evolution of Hfq's chaperone function among bacterial genera.
