Definition of myosin
Web(a) Three-domain structure of myosin. Myosins are comprised of an N-terminal motor domain (green), which contains the actin- and nucleotide-binding sites, a neck domain (purple), which consists of an α-helix stabilized by the binding of one or more light chains, and a C-terminal tail domain (brown), which is the most diverse region among the … Webmy·o·sin.

WebMyofilament. Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, a thin one of ...

Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP-dependent and responsible for actin-based motility. The first myosin (M2) to be discovered was in 1864 by Wilhelm Kühne. Kühne had extracted a viscous protein from skeletal muscle that he held responsible for keeping the tension state in mu…
