A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

It forms networks of thin, flexible filaments that affect the shape, stiffness, and movement of cells. Studies have found that aging alters actin expression, disrupting the cytoskeleton’s functions, ...

Actin is a highly abundant protein that controls the shape and movement of all our cells. Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin ...

Researchers at Kanazawa University report in eLife on deciphering the actin structure-dependent preferential cooperative binding of cofilin. The actin filament is a double-stranded helical structure ...

Historically, actin research at different levels of biological organization has developed into separate fields such as in vitro actin biochemistry, biophysics and cell biology. Biochemists, cell ...

Tiny things matter – for instance, one amino acid can completely alter the architecture of the cell. Researchers at the Universities of Göttingen and Warwick investigated the structure and mechanics ...

Understanding how microscopic interactions between proteins in cells produce large-scale organization and asymmetry is a fundamental question in cell biology.

The advantage of filamentous growth to the fungal lifestyle is so great that it arosemultiple times. Most zoosporic fungi from phylum Chytridiomycota exhibit a monocentric thallus form consisting of ...

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...
