Binding Site in Eag Voltage Sensor Accommodates a Variety of Ions and is Accessible in Closed Channel
In ether-à-go-go K(+) channels, voltage-dependent activation is modulated by ion binding to a site located in an extracellular-facing crevice between transmembrane segments S2 and S3 in the voltage sensor. We find that acidic residues D278 in S2 and D327 in S3 are able to coordinate a variety of div...
