Four types of proteins make up myofilaments
WebMyofilaments can be divided into three categories: scaffolding proteins (Z-disc, nebulin, titin, tropomodulin, alpha-actinin and CapZ proteins), contractile proteins (actin and myosin), and regulatory proteins (troponin and tropomyosin). Let's discuss each myofilament category in turn. Scaffolding proteins serve to demarcate the sarcomere.
