S1 constrains S4 in the voltage sensor domain of Kv7.1 K+ channels.
Voltage-gated K(+) channels comprise a central pore enclosed by four voltage-sensing domains (VSDs). While movement of the S4 helix is known to couple to channel gate opening and closing, the nature of S4 motion is unclear. Here, we substituted S4 residues of Kv7.1 channels by cysteine and recorded...
