Numerous motor and structural proteins compose a highly ordered structure known as the sarcomere, the basic unit of muscle contraction in heart and skeletal muscles. Sarcomeric myosin heavy chain ...

Type IIb fast-twitch myofibers, known for their rapid contraction speed, are plentiful in small mammals but have largely diminished in humans. Researchers at the University of Tsukuba have discovered ...

In a serendipitous discovery, UC San Diego researchers using cryo-EM technology captured the first visualizations of the 3-D structure of the muscle acetylcholine receptor in fetal and adult muscles.

Segments of the obliquely striated body muscle of Ascaris were fixed at minimum body length after treatment with acetylcholine and at maximum body length after treatment with piperazine citrate and ...

Research has uncovered how motor protein myosin, which is responsible for contraction of skeletal muscles, functions also in non-muscle cells to build contractile structures at the inner face of the ...

“This article illuminates the biology behind EDG-5506, demonstrating that modulation of fast skeletal muscle contraction protects against muscle injury, degeneration and fibrosis in models of DMD,” ...

Have you ever wondered about the biochemical mechanisms behind muscle contraction? If the answer is yes, then the (aptly named) Muscle Contraction app is for you! The app reads like an eBook, with ...

Scientists at the University of Cincinnati and colleagues report that a regulatory protein found in skeletal muscle fiber may play an important role in the body’s fight or flight response when ...
