Differential up-regulation of Na+-Ca2+ exchange by phosphoarginine and ATP in dialysed squid axons

The aim of this study was to characterize further the two main metabolic pathways of regulation of the Na + -Ca 2+ exchanger in squid axons induced by its two naturally ocurring high-energy compounds: ATP and phosphoarginine (Pa). [Na + ] o -dependent Ca 2+ efflux (forward - exchange) and [Ca 2+ ] o...
