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 ...

Researchers at the University of Liège, Eric Parmentier and Marc Thiry have just made the unexpected discovery of a novel organisation of muscle fibres in Parophidion vassali, a fish that lives in the ...

- Muscle cells, also known as myocytes, are specialized cells designed for contraction and force production. Skeletal Muscle Cells: These cells are long, cylindrical, and have a striated (or striped) ...

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 ...

Actomyosin is a protein complex composed of actin and myosin. It is found in muscle fibers where it plays a role in muscle contraction. Actin is one of the most abundant proteins in eukaryotes. It ...

Step aside, Fitbit. Data-driven fitness gadgets have nothing on this: A tiny, wearable microscope catches glimpses of muscles in action. The mini microscope, described in the Dec. 16 Neuron, can track ...

A remarkable protein that helps choreograph the highly specific series of events that ensure the heart beats consistently and accurately has been discovered by researchers. Called myosin-binding ...
