Ion Interactions in the High-Affinity Binding Locus of a Voltage-Gated Ca2+ Channel
The selectivity filter of voltage-gated Ca2+ channels is in part composed of four Glu residues, termed the EEEE locus. Ion selectivity in Ca2+ channels is based on interactions between permeant ions and the EEEE locus: in a mixture of ions, all of which can pass through the pore when present alone,...
