Scientists reveal how phosphate escapes from actin filaments

Actin filaments are dynamic protein-fibers in the cell built from single actin proteins. Many cellular functions, including cell movement, are regulated by constant filament assembly and disassembly. The disassembly phase ...

A new type of superresolution for exploring cell division

A new way to see details smaller than half the wavelength of light has revealed how nanoscale scaffolding inside cells bridges to the macroscale during cell division. Unlike earlier superresolution techniques, the one developed ...

Toxins force construction of 'roads to nowhere'

Toxins released by a type of bacteria that cause diarrheal disease hijack cell processes and force important proteins to assemble into "roads to nowhere," redirecting the proteins away from other jobs that are key to proper ...

Molecular tug-of-war gives cells their shape

In a new study, University of Maryland researchers have demystified the process by which cells receive their shape—and it all starts with a protein called actin.
