r-values represent the fraction of remaining ICa after 50, 100, 250, 500, 1000 and 5000 ms upon a 5 s depolarization to the voltage of maximal inward current (Vmax). All values are presented as mean ± SEM and originate from >3 independent transfections. Statistics: one-way ANOVA followed by Bonferroni multiple comparison post-test R498L8a-11-42 in comparison to Cav1.38a-42 and Cav1.38a-11-42; n, number of experiments.
