Abstract
Rapidly inactivating A-type potassium channels are important determinants of firing frequency in many excitable cells. Nadal et al. (in this issue of Neuron) purified A-type potassium (ISA) channels from rat cerebellum and identified a novel β subunit. This protein, DPPX, associates with the pore-forming subunits and endows previously elusive kinetic properties on A-type channels formed from cloned subunits.
