title: Expression of functional potassium channels from Shaker cDNA in Xenopus oocytes.
abstract: The Shaker gene of Drosophila melanogaster encodes a potassium-selective ion channel, the 'A' channel, or one of its subunits. A single Shaker messenger RNA species suffices to direct the synthesis of functional A channels in Xenopus oocytes. Physiological characteristics of the A currents induced by two different mRNA species are compared.
