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 … See more Domains Most myosin molecules are composed of a head, neck, and tail domain. • The head domain binds the filamentous actin, and uses ATP hydrolysis to generate force and to "walk" … See more The wide variety of myosin genes found throughout the eukaryotic phyla were named according to different schemes as they were discovered. The nomenclature can therefore be somewhat confusing when attempting to compare the functions of myosin proteins … See more Paramyosin is a large, 93-115kDa muscle protein that has been described in a number of diverse invertebrate phyla.
