The ability to modify the intracellular concentrations of divalent calcium ions is vital to normal cell functioning. In the cells of the cardiac muscle, calcium ions play a crucial role in coupling ...
Research on an inherited form of cardiac arrhythmia has now homed in on the elusive trigger of electrical instability in the heart. Aberrant calcium regulation emerges as a strong candidate. Figure 1: ...
During membrane depolarization associated with skeletal muscle excitation-contraction (EC) coupling, the L-type Ca 2+ channel (dihydropyridine receptor (DHPR) in the transverse (t)-tubule membrane) ...
