Large-conductance calcium-activated potassium (BK) channels are critical determinants of smooth muscle function by mediating rapid feedback between intracellular calcium levels and membrane potential.
Calcium ions orchestrate contraction and relaxation in airway smooth muscle by regulating excitation–contraction coupling. In quiescent cells, basal cytosolic Ca2+ is maintained at nanomolar levels by ...
Skeletal muscle is the type of muscle that controls movement. Problems with these muscles can be minor, life-threatening, or ongoing problems that make it hard to perform basic daily activities.
