摘要：

1. The human delayed rectifier K+ channel h-DRK1, a homologue to the DRK1 channel in the rat, was expressed in Xenopus oocytes. Single-channel currents were measured in micropatches; macroscopic currents were measured either in macropatches, giant patches, or whole oocytes. 2. Macroscopic currents activated at -20 mV and more positive. The instantaneous current-voltage relationship rectified outwardly to a higher degree than predicted by the Goldman-Hodgkin-Katz equation.
