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

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 ...

Potassium KCNQ2/3 channels are crucial for suppressing the excitability of brain cells, or neurons. When these channels don't work properly, they can cause specific types of epilepsy like benign ...

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 ...

Ion channels in the nervous system are among the most important targets for insecticides. Understanding the structure of the channels is key for the identification of novel species-specific binding ...

Ion selectivity is an important property of cell membrane ion channels. For example, potassium ion channels are more permeable to potassium ions than to sodium ions. The mechanism underlying the ready ...

Working independently, two European-led research groups may have uncovered an important clue to the mystery of amyotrophic lateral sclerosis (ALS), better known to some as Lou Gehrig or motor neuron ...

For decades it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers have now elucidated the transport path ...
