Multiple regulatory proteins bound to myosin and actin filaments are required for the structure and function of sarcomeres (Table 1). At least three gigantic proteins, titin, nebulin, and obscurin, play an important role on the function of sarcomeres. Each nebulin protein extends along the lengt...
Sodium-calcium (Na+-Ca+) exchanger activity undergoes developmental changes, including increased activity during fetal life and decreased activity during postnatal life. The primary function of this exchanger is to move calcium across the sarcolemma from the intracellular and extracellular compartments, pri...
