Time- and voltage-dependent inactivation of the NALCN current elicited by the wt, Y578S and L509S variants. (A) Voltage step protocol used to elicit representative current traces obtained in the presence of extracellular Na+ (B), in the absence of extracellular Na+ (C) and the corresponding trace subtraction to isolate the Na+-dependent component of the NALCN current (D) for mock-transfected cells (black traces), NALCN-wt-transfected cells (green traces), NALCN-Y578S-transfected cells (purple traces) and NALCN-L509S-transfected cells (blue traces). (E) Inactivation kinetics (time-constant, τ) of the Na+-dependent component of the wt (n = 7), NALCN-Y578S (n = 7) and NALCN-L509S (n = 6) currents in the −100 mV to −20 mV range. Statistical significance was calculated with a Tukey’s multiple comparisons test.
