Titin physiology
WebTitan is a giant protein found in the sarcomeres of skeletal and cardiac muscles. It is the largest known protein in mammals, with a molecular weight of over 3 million Daltons. Titan extends from the Z-disc to the M-line and interacts with several other proteins in the muscle, including myosin, actin, and titin-binding proteins. WebTitin spans an entire half-sarcomere (∼1 μm) from Z-disk to M-line . Overlap of titin molecules in both Z-disks and M-lines produces a titin filament system that is continuous …

Titin filaments span one half of the sarcomere, the contractile unit of striated muscles, and are extensible within the I-band region, where they link myosin-based thick filaments and actin-based thin filaments as viscoelastic springs (Fig. 1, A and B).These titin springs …
WebMar 15, 2024 · Titin is found at the Z disk and anchors myosin longitudinally within the sarcomere. Muscle fiber types can be broken down into three groups. Type I fibers, or slow oxidative fibers, are slow-twitching fibers. They are the smallest fiber type and have a low glycogen content.
