Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two further proteins, tropomyosin and troponin, regulate how myosin binds to actin. While theoretical ...

(Phys.org)—A team of researchers at Brandeis University in Massachusetts, has found that the CLIP-170 microtuble found in cells, which had been known to be important in cytoskeleton development, binds tightly to formins ...
(PhysOrg.com) -- Building on the work of a previous team that found filaments made from actin, when combined with so called motor proteins, moved themselves into distinct patterns, a new team in Japan has found that combining ...
Actin is the most abundant protein in the body, and when you look more closely at its fundamental role in life, it's easy to see why. It is the basis of most movement in the body, and all cells and components within them ...
