Figure 6.
Homotypic Hm-Inx1 gap junctions are not gated by junctional voltage. Voltage clamp recording from Hm-inx1-injected paired Xenopus oocytes. A, The trace shows the current in the passive cell required to maintain the holding potential of –80 mV when depolarizing and hyperpolarizing steps between ±10 and ±80 mV in 10 mV increments are applied to the driver cell. B, Graph of Gj versus Vj. Plot shows mean ± SEM; n = 5.
