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 ...

Actin filaments are protein fibers that make up the internal skeleton of the cell. As active elements of our cells, actin filaments support the cell's fusion, movement and are involved in many other ...

Living cells are highly organized, yet they are not assembled using rigid blueprints or by following a predetermined plan.

Actin filaments - protein structures critical to living movement from single cells to animals - have long been known to have polarity associated with their physical characteristics, with growing ...

Model showing the release of phosphate in different parts of the actin filament. Actin in the core of the filament has a closed door while the back door at the end of the filament is open. A mutation ...

Cells in the human body are made to move. They assemble during embryo development, migrate to repair tissue, hunt pathogens, and perform a host of other tasks requiring travel. As part of the ...

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

A tiny region in a little-known muscle protein may hold the key to a healthy, steady heartbeat, as well as possible clues to ...

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 ...

“We are answering fundamental questions of life that scientists have been trying to answer for several decades”, remarks Raunser. In eukaryotic cells, actin proteins are abundant and tend to join ...
