Researchers from the National Institute for Physiological Sciences, Nagoya City University, and Tokyo Metropolitan Institute of Medical Science in Japan have identified the first animal ion channel ...

Summary: For over a century, potassium ions were viewed as mere passengers in the brain—particles that flow through channels to generate electrical signals. However, a new discovery revealed that ...

Dr. Leal introduces amifampridine, an FDA-approved oral potassium channel blocker that increases acetylcholine release at ...

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 ...

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) ...

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 ...

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 ...

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 ...
