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 ...

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 ...

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 ...

Some cells, such as immune cells, are highly mobile—they constantly remodel their shape, migrate toward a wound that needs to be closed or chase down bacteria in the bloodstream. This mobility is ...

Skeletal and heart muscles contract and relax upon sliding of parallel filaments of the proteins myosin and actin. Nebulin, another long slender protein, which is present only in skeletal muscle, ...

Cancers that arise from epithelial cells often contain tumour cells that have acquired the characteristics of another cell type — a mesenchymal cell. A mouse model of skin cancer offers insights into ...
