Myosin is a type of motor protein that moves along actin filaments and generates force for muscle contraction, cell division, and intracellular transport. Discover how myosin works and how it is regulated by mechanobiology at MBInfo. Developing skeletal muscles express unique myosin isoforms, including embryonic and neonatal myosin heavy chains, coded by the myosin heavy chain 3 (MYH3) and MYH8 genes, respectively, and myosin light chain 1 embryonic/atrial, encoded by the myosin light chain 4 (MYL4) gene. These myosin isoforms are transiently expressed during embryonic and fetal development and disappear shortly after Myosins are among the most fascinating enzymes in biology. As extremely allosteric chemomechanical molecular machines, myosins are involved in myriad pivotal cellular functions and are frequently sites of mutations leading to disease phenotypes. Human β-cardiac myosin has proved to be an excellent target for small-molecule therapeutics for heart muscle diseases, and, as we describe here Myosins are molecular motors that use the energy from ATP hydrolysis to move and exert tension on actin filaments. Although the best-known myosin is myosin II, which powers skeletal muscle contraction, there are at least two dozen classes of myosins, and cells generally express multiple isoforms. Myosins are involved in multiple cellular Myosin is one of three major classes of molecular motor proteins: myosin, dynein, and kinesin. As the most abundant of these proteins myosin plays a structural and enzymatic role in muscle contraction and intracellular motility. Myosin was first discovered in muscle in the 19th century.
