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 ...

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 ...

Researchers have visualized at the molecular level how formins bind to the ends of actin filaments. This allowed them to uncover how formins mediate the addition of new actin molecules to a growing ...

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 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 ...

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.

When a nerve fiber in the spinal cord is severed, its repair may require that something else be severed: actin. In mature neurons of the central nervous system, actin is stable; that is, actin ...

Cancer cells are subjected to high mechanical pressure that leads to a rupture of the nuclear envelope when migrating through narrow tissue structures, as in the case of metastasis. DNA would normally ...

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 ...
