Figure 1.

N-terminal epitope tags do not alter the macroscopic properties of CCD-IRK3. Macroscopic K currents carried by the wild-type and VSV- and AU1-tagged channels in Xenopus oocytes are shown. Oocytes were held at O mV and pulsed in 10-mV increments from −150 to 50 mV. Families of current records from representative oocytes are shown on the left (current traces in 20-mV increments from −150 to 50 mV are shown). Current–voltage relationships for each of the channels are shown on the right.
