Structural and dynamic differences between selective and non-selective ion channels
(PHYSorg.com Chemistry)

Most ion channels are very selective about the ions that may or may not pass through them. They may be conductive for potassium ions and non-conductive for sodium ions, or vice versa. However, a number of ion channels allow for the efficient passage of both kinds of ions. How do these channel proteins accomplish this? A team of scientists around Dr. Han Sun and the research group of Professor Adam Lange at the Leibniz-Forschungsinstitut für Molekulare Pharmakologie (FMP) found the answer to this question.
