WebDeveloping muscle cells contain thick (myosin) filaments that are 160–170 Å in diameter and thin (actin)filaments that are 60–70 Å in diameter. Young myofibres contain a 7:1 ratio of thin to thick filaments. Myofilaments are the three protein filaments of myofibrils in muscle cells. The main proteins involved are myosin, actin, and titin. Myosin and actin are the contractile proteins and titin is an elastic protein. The myofilaments act together in muscle contraction, and in order of size are a thick one of mostly myosin, … See more There are three different types of myofilaments: thick, thin, and elastic filaments. • Thick filaments consist primarily of a type of myosin, a motor protein – myosin II. Each thick filament is … See more The protein complex composed of actin and myosin, contractile proteins, is sometimes referred to as actomyosin. In striated skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length in the order of a few … See more • Diagrams and explanations at biomol.uci.edu See more Other promising areas of research that may illumine the exact molecular nature of exercise-induced protein remodeling in muscle may be the study of related proteins involved with cell architecture, such as desmin and dystrophin. These proteins are thought … See more

Increased ADP sensitivity in IDCM, HCMsmn, and MYH7(mut) was caused by low phosphorylation of myofilament proteins, as it was normalized to donors by protein kinase A (PKA) treatment Troponin exchange experiments in a TNNT2(mut) … bmf paintball
