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 ...

Small Molecules CK-666 and CK-869 Inhibit Actin-Related Protein 2/3 Complex by Blocking an Activating Conformational Change. Chemistry & Biology , 2013; 20 (5): 701 DOI: 10.1016/j.chembiol.2013.03.019 ...

What was seen in the Arp2/3 complex, Nolen said, will help to understand precisely how actin is controlled in cells. "Cell motility requires actin inside the cell to constantly be remodeled," he said.

Gamma-actin therefore confers increased rigidity to the apical membrane, forming a network of filaments that is stronger and stiffer than that made up of beta-actin filaments.

The reason this paper is so important to many other researchers, says Rayment, is that the "three-dimensional structure [of myosin] gives a molecular framework that is essential for understanding how ...

The motion of motor proteins on biopolymers is important for diverse biological processes. Actin, microtubules, and nucleic acids can serve as one-dimensional tracks on which motor proteins move.

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 ...

Scientists have uncovered new details about cellular filaments that play a critical role in wound healing, according to a study published in the Proceedings of the National Academy of Sciences.
