Streptavidin binding to the proximal portion of the α1S II–III loop has little effect on calcium currents. (A) Currents were recorded from a dysgenic myotube expressing α1S(671-BAD-686)-YFP that was injected with streptavidin-rhodamine >2 h before recording. The plot shows the I-V relationship for α1S(671-BAD-686)-YFP currents following streptavidin injection. (B) The average amplitudes of calcium currents evoked by a 200-ms voltage step to +40 mV from α1S(671-BAD-686)-YFP–expressing myotubes that were not (−SA, n = 4 cells) or were (+SA, n = 8 cells) injected with streptavidin.
