The action of Na+ as a cofactor in the inhibition by cytoplasmic protons of the cardiac Na(+)-Ca2+ exchanger in the guinea-pig.
1. Na(+)-Ca2+ exchange current was activated in giant excised patches of guinea-pig cardiac sarcolemma by raising the intracellular sodium concentration ([Na+]i). When the pHi was simultaneously acidified to 6.4, the current was transient, dropping by 80% in 30 s. 2. Pre-exposure to a pHi of 6.4 for...
