MinK-KvLQT1 Fusion Proteins, Evidence for Multiple Stoichiometries of the Assembled I Channel

Abstract excerpt

IsK, a slowly activating delayed rectifier K+ current through channels formed by the assembly of two channel proteins KvLQT1 and MinK, modulates the repolarization of cardiac action potentials. Mutations that map to the KvLQT1 and minK genes account for more than 50% of an inherited cardiac disorder, the Long QT syndrome (Splawski, I., Tristani-Firouzi, M., Lehmann, M. H., Sanguinetti, M. C., and Keating, M. T....
