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

A buildup of a structural protein called F-actin inside aging brain cells appears to cripple the cellular waste-clearing machinery that keeps neurons healthy, according to a study in Drosophila fruit ...

The actin cytoskeleton is a dynamic network made up of actin polymers and associated actin binding proteins. The actin cytoskeleton was originally isolated as a component of the actomyosin complex in ...

The cytoskeleton of eukaryotic cells is made of filamentous proteins, and it provides mechanical support to the cell and its cytoplasmic constituents. All cytoskeletons consist of three major classes ...

The dynamic processes that occur during the growth of actin, via polymerization, and the breakdown of actin both play significant roles in cellular mechanisms like migration and adhesion. Due to the ...

Actin-based cell motility is a complex process involving a dynamic, self-organizing cellular system. Experimental problems initially limited our understanding of this type of motility, but the use of ...

Depositphotos A closer examination revealed that the F-actin had messed up the cell’s recycling system. The researchers found that preventing F-actin accumulation, caused more autophagy in the brains ...

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 ...

Cancer cells have evolved multiple escape strategies to circumvent the body's immune defenses such as the attack by Natural Killer (NK) cells which normally swiftly kill abnormal cells by releasing ...

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

Chara corallina myosin XI (CcXI) drives the movement of actin filaments, which spontaneously form ring-like structures due to a slight curvature that leads to polar alignment.

In the rapidly evolving arena of regenerative science, two peptides – BPC‑157 (Body Protection Compound‑157) and TB‑500 (a short‑chain analogue of thymosin β4) – have garnered increasing interest for ...
