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 ...

Cells have an internal skeleton that maintains their structure and also drives their movement. Known as the cytoskeleton, ...

Right: Cells whose actin filaments were disrupted. Time zero indicates the beginning cell plate formation. The phragmoplast microtubules are yellow, and the cell plate is magenta. Using microscopic ...

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 ...

The three-dimensional structure of a protein involved in the assembly of actin filaments could help to settle a long-standing scientific debate about the regulation of cytoskeletal organization. The ...

The formation of the branched actin networks is essential for cell polarity, but it remains unclear how the debranching activity of actin filaments contributes to this process. Here, we showed that an ...

Actin filaments are dynamic protein-fibers in the cell built from single actin proteins. Many cellular functions, including cell movement, are regulated by constant filament assembly and disassembly.

Actin filaments are part of the cell skeleton and essential for stability and motility. They form a network that dynamically builds up and gets broken down by the addition or detachment of building ...

Dynamic behavior of actin filaments in cells is the basis of many different cellular activities. Remodeling of the actin filament network involves polymerization and depolymerization of the filaments.
