According to my Physiology text yes, Myosin is.
Myosin
Thick filaments are made of the protein myosin and thin filaments are made of the protein actin. Myosin and actin filaments are arranged to form and overlapping pattern which gives muscle tissue its striated appearance.
Proteins build our cells, tissues and there by body. Muscle protein actin and myosin are responsible for muscle contraction. collagen is an important protein of connective tissue such ligaments, tendons, bones and teeth.
actin and myosin
The two filaments involved are myosin and actin. Actin: is the framework and slides over the myosin filament when the muscle is shortened. myosin: is a thick filament Also a sacromere: is made up of the actin and myosin. It is the functional unit of a muscle fibre and extends from z line to z line. A muscle contraction: is many sacromeres shortening ( actin sliding over myosin)
Most myosin molecules are composed of both a head and a tail domain.
Actin is found in muscle tissue ( along with myosin) and makes up microfilaments which are responsible for cellular movement and also function in cell division.
myosin
Calmodulin on myosin heads
Actin and Myosin are the basic muscle tissues.
A muscle is made of many cylindrical muscle fibers. The many fibers are bound together with connective tissue. Nerves and blood vessels (arteries and veins) run along the connective tissue.In every muscle fiber, there are thick filaments, made of the protein myosin, and thin filaments, made of the protein actin. The filaments overlap to form the sarcomere, a part of the muscle. Myosin has little heads that attach to actin, and pull on it. This is when the sarcomere contracts, and when all of the sarcomeres of a muscle contract, the entire muscle contracts.
I understand that Protein can repair muscle tissue as it is the only macronutrient that has nitrogen apart from carbon, hydrogen & oxygen. But why does the inclusion of nitrogen make protein capable of repairing muscle tissue? What is Nitrogens role in Muscle tissue repair?
