Short review of some properties of muscular proteins.

Proteins are the basic material of tissue structure. They are the most important component of striated skeletal muscle. Their classification is correlated with the histological structure of muscle tissue. The muscle proteins can be divided in to contratile, regulatory, sarcoplasmic and extracellular forms. The most important are the contractile proteins actin and myosin. Among the regulatory proteins, troponin, tropomyosin, M-protein, beta-actin, gamma-actin and C-protein are great importance. Sarcolemma is also a protein component. Proteins such as myoglobin, myogen, myoalbumin and x-globulin are found in the sarcoplasm and proteins such as elastin, collagen and reticulin are also found in the muscle. The remaining of proteins includes myofibrillar proteins of the Z-disc as well as small quantities of other proteins. This work is a short review of some properties of the muscular proteins.
