A tiny chemical modification on one of the most abundant and important proteins in cells, actin, has long been somewhat mysterious, its function not fully understood, but scientists have now taken a ...

Over the last several years the identification and functional characterization of the motor proteins actin and myosin in the nucleus has initiated a change in the view of nuclear processes. It is now ...

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, ...

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 ...

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 ...

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 ...
