Abstract excerpt
We demonstrated that overexpression of a cRNA encoding a truncated potassium channel polypeptide that contains the NH2 terminus and the first transmembrane segment (Kv1.1N206Tag) abolished the expression of Kv1.1 and Kv1.5 outward currents in Xenopus oocytes (Babila, T., Moscucci, A., Wang, H., Weaver, F. E. & Koren, G. (1994) Neuron 12, 615-626). Recently, we showed that expression of Kv1.1N206Tag in the heart...
