Scientists are bringing the basis of muscle movement into sharper focus. Muscle contraction and many other movement processes are controlled by the interplay between myosin and actin filaments. Two ...
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 ...
The structure of the calcium-bound core of human cardiac troponin reveals distinct subdomains connected by flexible linkers, implying that domain reorientation motions within the complex trigger ...
In several disorders that involve muscle dysfunction — such as amyotrophic lateral sclerosis, spinal muscular atrophy and myasthenia gravis — muscle weakness results from limited neuronal input into ...
