KV7.1 (KVLQT) - current-voltage relationship
Patchliner data and applications:

KCNQ1/KCNE1 expressed in CHO cells was activated using increasing voltage steps. Shown are traces from an example cell and the normalized current-voltage plot for an average of 8 cells. The IKs current mediated by KCNQ1/KCNE1 started to activate at approximately -20 mV and increased with each voltage step (increment 10 mV). The normalized IV curve was fit using a Boltzmann equation revealing a Vhalf of activation of 25 mV.
