(September 29, 2005, La Jolla, CA) Scientists from the Burnham Institute for Medical Research and the University of Vermont have captured the first 3-dimensional (3D) atomic-resolution images of the ...

Cell generated force plays essential roles in a wide range of biological processes, such as cell motility, cytokinesis, and tissue morphogenesis. In a study published in Nature Communications, a ...

Extracts of the soluble cytoplasmic proteins of the sea urchin egg form gels of different composition and properties depending on the temperature used to induce actin polymerization. At temperatures ...

An electron microscopy study revealed key details of actin filaments, which are essential structural elements of cells and muscles. Actin filaments -- protein structures critical to living movement ...

The organization of actin filaments into higher-ordered structures governs eukaryotic cell shape and movement. Global actin network size and architecture are maintained in a dynamic steady state ...

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 ...
