NvErg4 currents are DmErg-like. (A) NvErg4 currents recorded in response to 1 s depolarizations ranging from –110 mV to +50 mV in 20 mV increments from a holding potential of –100 mV; tail currents were recorded at –70 mV. (B) NvErg4 GV curve compared with NvErg1, DmErg, and HsErg1. NvErg4 data were measured from isochronal tail currents recorded at either –50 mV or –70 mV following 1 s depolarizations to the indicated voltages (mean ± SEM, n =11). Single Boltzmann fit (curves) parameters are given in Table 1. NvErg4 sequence information can be found in Datasets S1 and S2.
