Supplementary Figure 3: Single-channel i/V curve of BLINK2.
From: A light-gated potassium channel for sustained neuronal inhibition
BLINK2 single-channel currents (blue symbols) plotted as a function of voltage. Currents for BLINK1 (white circle) and KcvPBCV1 (black circle) are shown for comparison. Each data point is the average of n = 3 measurements performed in cell-attached configuration (BLINK2) or after insertion of purified proteins in planar lipid bilayers (BLINK1 and KcvPBCV1) in n = 3 independent experiments. Standard deviations are within the dimensions of the symbols. Recordings were performed in the following conditions: 103 mM K+ in the pipette solution for BLINK2 and symmetrical 100 mM K+ (BLINK1 and KcvPBCV1).
