Increased titin compliance reduced length-dependent contractionand slowed cross-bridge kinetics in skinned myocardial strips from Rbm20ΔRRM mice

Titin is a giant protein spanning from the Z-disk to the M-band of the cardiac sarcomere. In the I-band titin acts as a molecular spring, contributing to passive mechanical characteristics of the myocardium throughout a heartbeat. RNA Binding Motif Protein 20 (RBM20) is required for normal titin spl...
