↵F1-a All values are mean ± SEM; current densities and τ_decay values were determined from currents recorded on depolarizations to +50 mV; n= number of cells.
↵F1-b Data from Malin and Nerbonne (2000).
↵* Values in Kv4.2W362F-expressing cells are significantly (p < 0.04) different from those recorded in wild-type cells.
↵F1-160 Values in Kv1.5W461F-expressing cells are significantly (p < 0.001) different from those recorded in Kv4.2W362F-expressing cells.
