Titin function
WebFeb 16, 2010 · The giant protein titin is thought to play major roles in the assembly and function of muscle sarcomeres. Structural details, such as widths of Z- and M-lines and periodicities in the thick filaments, correlate with the substructure in the respective regions of the titin molecule. WebJun 16, 2024 · Titin provides structural support and elastic forces to heart tissue while being stretched. Length and viscoelasticity are predominant components of the passive tension during the heart systaltic process and the major contributors to the Frank-Starling mechanism ( 28, 29 ).
