How many classes of myosin are there
WebApr 6, 2024 · Myosin is composed of a globular head that has both Adenosine triphosphate (ATP) and actin-binding sites and also a long tail that is involved in its polymerization into the myosin filaments. Actinomycin is the name given to the protein complex, which is composed of both actin and myosin. WebOct 4, 2024 · A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins specially arranged within the cell. While several associated proteins help, actin and myosin form thick and thin filaments which slide past each other to contract small units of a muscle cell.
