Small vertical movement of a K+ channel voltage sensor measured with luminescence energy transfer

Voltage-gated ion channels open and close in response to voltage changes across electrically excitable cell membranes 1 . Voltage-gated potassium (Kv) channels are homotetramers with each subunit constructed from six transmembrane segments, S1–S6 (ref. 2 ). The voltage-sensing domain (segments S1–S4...
