Internal MTSET induces a persistent current in the I1770C mutant. (A) The currents of the I1770C mutant measured in reagent-free pipette solution. Currents are shown immediately after break-in (P1) and after 0.5, 1, 3, 5, and 8 min (P100). (B) Currents of the I1770C mutant with 1 mM MTSET in the patch pipette. (C) Peak currents measured in the absence and presence of MTSET. (D) Persistent current measured after 25 ms of depolarization.
