Fig. 3. Recovery of currents carried by the human Cav2.3 subunit. Protocols were as described in Fig. 2, with the exception that a 9.5 s prepulse
was used to inactivate the current (16.2 s for the Cav2.3+L2a combination). A: Recovery of Cav2.3 expressed alone or coexpressed with
the cyL, L2a, L3, or L4 subunits after an interpulse of 3110 mV. B: Recovery of the subunit combinations shown in (A) after an interpulse of
360 mV. C: Examples of recovery of the hCav2.3 subunit expressed alone (closed circles) or coexpressed with L3 (open triangles) or L4 (open
diamonds). The currents shown were elicited by test pulses after a 9.5 s prepulse to +10 mV followed by a 500, 900, or 1300 ms interpulse step
to 360 mV. Note the di¡erence in time scale between the two halves of the ¢gure. D: Voltage dependence of recovery. Symbols are as described
in (A); the hCav2.3+L2a combination was not tested in this experiment. n =4^10 cells.
