Abstract
Single K+ channels were recorded under the cell-attached mode in Xenopus oocytes injected with an equal amount of mRNAs coding for NGK1 (Kv1.2) and NGK2 (Kv3.1a) voltage-dependent K+ channels. A new class of channels of 20 pS in conductance with three degrees of inactivation was observed. The results suggest that voltage-dependent NGK1 Shaker and NGK2 Shaw K+ channels, from different subfamilies, assemble to form heteromultimeric K+ channels in Xenopus oocytes and show characteristics inherited from two parental channels.
