Kv7.1 current amplitude is reduced by extracellular potassium. (A) Representative currents from Kv7.1 channels recorded in 1 (solid) and 10 (shaded) mM [K+]o. The voltage-clamp protocols are shown above the corresponding recordings. (B) Steady-state current-voltage (I/V) relationship for Kv7.1 channels in 1 (solid) and 10 (shaded) mM [K+]o. (C) Normalized steady-state conductance-voltage (G-V) relationship for Kv7.1 channels in 1 and 10 mM [K+]o. Boltzmann functions (solid lines) were fitted to the data.
