Myosin secondary structure

Myosin II (also known as conventional myosin) is the myosin type responsible for producing muscle contraction in muscle cells in most animal cell types. It is also found in non-muscle cells in contractile bundles called stress fibers . See more 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. See more Domains Most myosin molecules are composed of a head, neck, and tail domain. • See more Note that not all of these genes are active. • Class I: MYO1A, MYO1B, MYO1C, MYO1D, MYO1E, MYO1F, MYO1G, MYO1H • Class II: MYH1, MYH2, MYH3, MYH4, MYH6, MYH7, MYH7B See more • Gavin RH (2001).
