Cloning and functional expression of a TEA‐sensitive A‐type potassium channel from rat brain

Abstract
A rat brain cDNA (Raw3) related to the Drosophila Show K* channel family has been characterized, Raw3 cRNA leads to the formation of TEA-insensitive, fast inactivating (A-type) K* channels when injected into Xenopus leavis oocytes. Raw3 channels have markedly different properties from the previously cloned rat A-type K* channel RCK4, Raw3 channels operate in the positive voltage range
