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. 1. … Zobacz więcej The contraction of skeletal muscles is responsible for all kinds of movements exhibited by animals. This contraction is possible due to the contractile proteins present inside the skeletal muscle cells. The contractile … Zobacz więcej Myosin is a family of filamentous motor protein that is divided into different classes or groups. These classes differ concerning their structure, location of genes, and functions. Some … Zobacz więcej Myosin is a filamentous protein that belongs to the category of motor proteins.
