Gap junctions are intracellular proteins located at areas of cell to cell contacts. In the heart these structures are essential for the electrical communication that ensures the normal and coordinated propagation of the cardiac action potential. Gap junctions are a part of a macromolecular complex, the intercalated disc that is also composed of mechanical junctions necessary for the structural integrity of the cardiac tissue. Our present focus is on the interdependence of gap junctions and the components of these mechanical junctions. Also of interest are interactions between cardiac gap junctions and the sodium channel complex.
