    The giant muscle protein titin contributes to the filament system in skeletal and cardiac muscle cells by connecting the Z disk and the central M line of the sarcomere. One of the physiological functions of titin is to act as a passive spring in the sarcomere, which is achieved by the elastic properties of its central I band region. Titin contains about 300 domains of which more than half are folded as immunoglobulin-like (Ig) domains. Ig domain segments of the I band of titin have been extensively used as templates to investigate the molecular basis of protein elasticity.
