The plasma membrane calcium ATPase (PMCA) of neurones is electroneutral and exchanges 2 H(+) for each Ca(2+) or Ba(2+) ion extruded
The coupling between Ca(2+) extrusion and H(+) uptake by the ubiquitous plasma membrane calcium ATPase (PMCA) has not been measured in any neurone. I have investigated this with Ca(2+)- and pH-sensitive microelectrodes in large voltage-clamped snail neurones, which have no Na(+)–Ca(2+) exchangers. T...
