The amino-terminus of Rem allows the low P_o mode of channel inhibition. Representative recordings of (A, left panel) L-type currents and (B, left panel) intramembrane charge movements obtained from FDB fibers expressing V-RemNT-Rad. (A and B, right panels) The I-V and Q-V relationships corresponding to each current family. Peak I/V data for naïve FDB fibers and fibers expressing V-Rem are replotted from Fig. 1. Q-V data for fibers expressing either V-Rem or V-Rad are replotted from Fig. 2.
