Intramembrane charge movements in FDB fibers are reduced by Rad, but are not affected by Rem. Representative recordings of intramembrane charge movements elicited by 25-ms depolarizations from −80 mV to −50 mV, −40 mV, −30 mV, −20 mV, −10 mV, 0 mV, +10 mV, and +20 mV are shown for a naïve FDB fiber (A, left) and transfected fibers expressing V-Rad (B, left panel) or V-Rem (C, left panel). (A–C, right panels) The Q-V relationships corresponding to each current family. (A, right panel) The Q-V relationship for fibers expressing nonfused YFP is also shown. Charge movements were evoked at 0.1 Hz by test potentials ranging from −70 mV through +50 mV in 10-mV increments. (Smooth curves) Plotted according to Eq. 2 with fit parameters displayed in Table 1.
