Inactivation properties of ω-AgTx-IVA-sensitive currents in tgla/+ andtgla/tglacells. A1, A2, Voltage dependence of inactivation was described using a Boltzmann function. Thetgla/+ currents exhibited a half-inactivation voltage of −41.2 mV (k = 13.2), and thetgla/tglacurrents were half-maximally inactivated at −55.6 mV (k = 17.4).B1, B2, Percent inactivation was 51% for thetgla/+ current and 67% for thetgla/tglacurrent.
