Actin filaments are the smallest type, with a diameter of only about 6 nm, and they are made of a protein called actin. Intermediate filaments, as their name suggests, are mid-sized, with a ...

The new structures, with resolutions around 3.5 Ångstrom, show that formins encircle actin like an asymmetric ring: One half of the ring is stably bound, while the other half is loosely ...

The actin cytoskeleton provides force for dynamic cellular processes, such as motility, morphogenesis, cell division, endocytosis, and phagocytosis. The organization and dynamics of actin filaments ...

Actin is a highly abundant protein that controls the shape and movement of all our cells. Actin achieves this by assembling into filaments, one actin molecule at a time. The proteins of the formin ...

Troponin I, troponin T, and myoglobin concentrations were determined by immunoassay and α-actin concentrations by Western blot and densitometry. Results: The mean serum concentration of α-actin in ...

Researchers at the Universities of Göttingen and Warwick investigated the structure and mechanics of the main component of the cytoskeleton of the cell: a protein known as actin. Artificial cells ...
