Single-channel recordings of the cell-cell channel formed by the V181A and E102G mutants. Ramps were applied to cell 1 from -120 to +120 mV, and currents were recorded in cell 2. a, Single-channel currents from cells expressing the V181A mutant. b, Single-channel currents from cells expressing the E102G mutant. c, Graphic representation of the voltage waveform applied to cell 1. The sizes of the major transitions (arrows) for both channels (∼50-55 pS) were similar to what we (data not shown) and others (Oh et al., 1997) have observed for 32WT.
