Biophysical characteristics.

<p><b>A</b>, illustrates half-activation voltages (V₅₀) of currents resulting from expression of Kv7.1 with respective constructs. Mean±SEM V₅₀ values were similar between constructs ‘38S’: 5.8±3.7 mV, ‘38G’: −2.7±4.1 mV, ‘Δ1-38’: 6.0±4.1 mV, ‘linker’: 1.0±2.5 mV, ‘38S-3xA’: 3.4±8.6 mV, ‘38G-3xA’: 8.7±6.8 mV; <i>P</i> = n.s vs. ‘38S’. Lines shown are Boltzmann fits to mean data (obtained with the formula: A = A₀/(1+exp[(V₅₀-V)/S])). <b>B</b> shows results of mono-exponential fits (y = A^(−t/τ)+C) to activating currents with time-constants plotted over a test potential of 0 mV. <b>C</b> shows results of mono-exponential fits to deactivating ionic currents. Currents obtained from co-transfection of Kv7.1 with ‘linker’ and ‘38S-3xA’ deactivated more slowly than currents obtained with the remainder of the constructs (<i>P</i><0.05 vs. ‘38S’). TP – test potential.
