Shaker-type K(+) channels in plants display distinct voltage-sensing properties despite sharing sequence and structural similarity. For example, an Arabidopsis K(+) channel (SKOR) and a tomato K(+) channel (LKT1) share high amino acid sequence similarity and identical domain structures; however, SKOR conducts outward K(+) current and is activated by positive membrane potentials (depolarization), whereas LKT1 conducts inward current and is activated by negative membrane potentials (hyperpolarizat ...[more]
