Larger Image Figure 4. Y464A hEAG1 channels exhibit enhanced inactivation. (A) Voltage-pulse protocol and corresponding Y464A hEAG1 currents. (B) Test-pulse currents (during time indicated by a solid bar in A) are shown on an expanded time scale. Test currents elicited after Vpre of −130, −85, −70, and −40 mV are labeled. A fast inactivating component of current is evident when Vpre ≥ −70 mV. Image published in: Garg V et al. (2012) © 2012 Garg et al.
