Non-native R1 substitution in the s4 domain uniquely alters Kv4.3 channel gating.
The S4 transmembrane domain in Shaker (Kv1) voltage-sensitive potassium channels has four basic residues (R1-R4) that are responsible for carrying the majority of gating charge. In Kv4 channels, however, R1 is replaced by a neutral valine at position 287. Among other differences, Kv4 channels displa...
