摘要：

A common mechanism affecting Ca2+ sensitivity in skeletal muscle is the proximity of myosin heads with actin filaments, a function of myofilament lattice spacing and myosin head mobility with respect to the myosin filament. This is an important mechanism of pCa(50)(2+) modulation by length, pH, regulatory light-chain phosphorylation, and temperature.
