The dependence of the membrane potential of Eremosphaera viridis on different external concentrations of potassium, sodium, calcium, and protons was compared with the diffusion potential measured in ...

Potassium channels are openings that allow charged potassium atoms to cross the cell membrane. Voltage-gated potassium channels — which open only when a specific voltage is reached across the cell ...

Pioneering studies in voltage-gated potassium channels have described movement of the voltage-sensing domain (VSD) S4 helix across the membrane electric field in molecular detail, but much less is ...

A key approach to understanding the brain is to observe the behavioral effects of turning on specific populations of neurons. One of the most popular approaches to controlling neuronal activity in ...

Monash University researchers have developed a faster, more efficient nanodevice to filter proton and alkaline metal ions which will help design next-generation membranes for clean energy technology, ...

A single mutation in a gene, Kcnc3, which encodes a potassium channel in neurons, causes learning deficits in mice, UT Southwestern researchers report in a new study in PNAS. The novel mutation ...

Defying one of biology’s more persistent dogmas, a potassium channel combines functions once thought to be invariably asunder. This channel, which is found in common bacteria, incorporates a subunit ...

Lysosomes require tight regulation of their pH to degrade their contents. Researchers know that V-ATPase pumps protons into these little digestive sacs, but what protein shuttles the ions back out?

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes various symptoms that go beyond respiratory problems. Neurological, cardiac, and other issues can emerge during infection and after ...
