One of the functionally most complex sub-compartments of the sarcomere is the Z-disc that forms the lateral boundaries between adjacent sarcomeres. This region plays a central role as the site organizing thick filaments and titin into the molecular machinery that is required for muscle contraction and comprises the actin, titin, and nebulin filaments. | One of the functionally most complex sub-compartments of the sarcomere is the Z-disc that forms the lateral boundaries between adjacent sarcomeres.
