Do only potassium ions pass through the selectivity filter of a potassium channel, or are there water molecules between the ions? This question has been a source of controversy for years. Researchers ...

Potassium channels are responsible for the selective permeation of K⁺ ions across cell membranes. K⁺ ions permeate in single file through the selectivity filter, a narrow pore lined by backbone ...

Most ion channels are very selective about the ions, which 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 ...

Scientists recently completed a study in which they attempted to capture at atomic resolution a picture/snapshot of one of the two ion-bound configuration that seem to coexist within the selectivity ...

The design of new calcium channels, built bottom-up from scratch, was reported last week in Nature. "Biochemists have been studying ion channels for decades and debating about how they work for almost ...
