Potassium channel block by internal calcium and strontium
We show that intracellular Ca blocks current flow through open K channels in squid giant fiber lobe neurons. The block has similarities to internal Sr block of K channels in squid axons, which we have reexamined. Both ions must cross a high energy barrier to enter the blocking site from the inside,...
