The giant muscle protein titin acts as a crucial integrator of diverse myocyte signaling pathways, including protein quality-control, hypertrophic gene activation, and mechanosensing.
The giant muscle protein titin, the "backbone" of the sarcomere, harbors a complex molecular spring whose stiffness is variably tuned in health and disease. Titin is increasingly recognized as a crucial integrator of diverse myocyte signaling pathways. The titin-associated signalosome includes hotspots of protein-protein interactions important for the regulation of protein quality-control mechanisms, hypertrophic gene activation, and mechanosensing.
Linke et al. (Tue,) reported a review. Titin was evaluated. The giant muscle protein titin acts as a crucial integrator of diverse myocyte signaling pathways, including protein quality-control, hypertrophic gene activation, and mechanosensing.
