ProteomicsEnlightening the decay: a combined experimental and computational analysis of mantATP turnover in skinned muscle fibers
Myosin is the primary motor protein in skeletal muscle, responsible for ATP hydrolysis that drives muscle contraction. In addition to force production, myosin consumes ATP during rest in futile cycles, a phenomenon associated with the Super Relaxed State (SRX), distinct from the disordered Relaxed S...

ProteomicsResting skeletal muscle reduces ATP turnover during hibernation
In mammals, loss of food intake and reduced mechanical loading/activity of skeletal muscles leads to a very rapid loss in mass and function. However, during hibernation in bears, despite spending months without feeding and with very modest muscle activity, only moderate muscle wasting is observed. P...
