(Phys.org)—A small team of researchers from Stanford University has synthesized the neurotoxin present in the skin of the poison dart frog. In their paper published in the journal Science, the team describes how they accomplished ...
(Phys.org)—One of the mysteries in biology is how cells can selectively diffuse potassium across a membrane. Biological systems rely on a delicate balance between these potassium and sodium ion concentrations in the surrounding ...
The transmembrane protein 206 abbreviated as TMEM206 is an evolutionarily conserved chloride channel that underlies the ubiquitously expressed, proton-activated, outwardly rectifying anion currents. In a new report now published ...
Unique genetic re-wiring of a sodium channel explains how a family of electric fish can generate the highest frequency of electrical discharge seen in any animal. In a study publishing 27 March in the open access journal ...

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms—ions—but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in ...

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 ...
