Abstract excerpt

Unitary currents were recorded from inside-out membrane patches pulled from Xenopus oocytes that had been injected with RNA transcribed from a cDNA encoding the Drosophila maxi-K channel (Slowpoke). Site-directed mutagenesis was used to make cDNAs encoding channel subunits with single amino acid substitutions (Y308V and C309P). The extracellular side of the patch was exposed to tetraethylammonium (TEA) in the...
