WebIntroduction. Myosins constitute a large multigene family of actin-based molecular motors, which are essential to eukaryotic homeostasis across the phylogenetic spectrum. Myosins are involved in growth and tissue formation, metabolism, reproduction, communication, reshaping, and movement of all 100 trillion cells in the human body. the patio drafthouse midland txWebSummary. Myosin is a contractile protein found in the muscles of animals as well as non-muscle cells. It is responsible for muscle contraction as well as intracellular transport. Myosin is made of six subunits including two heavy chains and four light chains. The molecule is considered to be made up of three domains. the patio downers groveWebApr 13, 2024 · The valid top 150 differential genes were input into the cMAP database to predict the small molecular compounds targeting these genes (Table S2).
