**Figure 5. **Junctional current (I_{j})
data
from paired oocytes. The left column shows examples of current
traces recorded from homotypic pairs (Cx43/Cx43 and Cx46/Cx46), a
heterotypic pair (Cx43/Cx46), and a heteromeric pair (Cx43•46/Cx43•46).
The right column plots normalized steady-state junctional conductances
(filled circles) measured at the end of 10-s-long voltage steps, and
fit to the Boltzmann equation (curved lines).
