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 ...

A new class of soft, electrically activated devices is capable of mimicking the expansion and contraction of natural muscles. These devices, which can be constructed from a wide range of low-cost ...

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.

The basic functional unit of a muscle, known as the sarcomere, consists of actin, myosin and tropomyosin proteins. If a muscle is to be able to contract, the myosin must slide along filamentous actin ...

Cancer patients often lose excessive amounts of weight. This affects up to 80% of patients and is mainly due to a decrease in muscle mass and fatty tissue. This cancer-induced cachexia (CIC) is ...
