Ubiquitous in living organisms, potassium ion channels help provide energy to cells. In excitable cells such as neuron and muscle cells, the proteins also function to transmit signals from one part of a cell to another.

Despite more than 50 years of research, however, questions still remain about exactly how these channels do their job. Scientists do know that the channels, which sit in cell membranes, establish an electric potential between the inside and outside . . .
