'''Figure 1''' ''Schematic overview of the basic muscle contractile unit: sarcomere. Myosin filaments are shown in the middle in blue. Actin filaments are depicted as orange helical structures at the top and bottom of the diagram. Titin with its elastic properties in its I-band region is indicated by symbolic coiling (in grey). Nebulin is shown in grey, wrapping around actin filaments. The Z-disc and the M-band comprise additional protein networks, as shown by grey areas, crosslinking individual filament systems.'' | |||
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.
