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 ...

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 ...

Structures of the human M-channel reveal a remarkably flexible assembly and the molecular basis for its subthreshold ...

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 ...

Research develops a better understanding of and exerts an unparalleled control of protein molecules. For the first time ever, researchers at the Texas Tech University Health Sciences Center (TTUHSC) ...

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 ...

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 ...

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 ...

Voltage-gated potassium (Kv) channels play an important role in modulating the electrical activity of cells, opening in response to changes in membrane voltage and allowing potassium ions to escape.

For decades, it was assumed that protein channels and protein pumps fulfilled completely different functions and worked independently of each other. Researchers at Goethe University Frankfurt and ...
