FIGURE 2.
Effect of THGP on ROMK currents. A, representative whole cell currents from Xenopus oocytes injected with ROMK2 (left) or THGP (middle) or both (right) are shown. B, macroscopic current-voltage relationships and C, currents activated at −100mV were plotted. D, Xenopus oocytes injected with HA-tagged ROMK2 alone or together with THGP were assayed for surface expression, as determined by a cell surface luminescence assay. E, corresponding Western blots of HA-tagged protein in total oocyte lysates. Water-injected oocytes were taken as control to determine antibody specificity (n = 15, ***, p < 0.0001 versus ROMK2).
