Researchers have identified two ion channel switches that regulate the release of dopamine in the brain, a first step that might one day lead to therapeutics for a wide range of diseases and disorders ...

Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant ...

In the human body the salt content of cells and their surrounding is regulated by sophisticated transport systems. Special channels in the cell membrane selectively permit salt ions to flow in and out ...

Tandem mass spectrometry is a powerful tool in proteomics. By ionizing peptides and then fragmenting those ions into smaller product ions, researchers can determine the biomolecules’ amino acid ...

Researchers have developed a method for identifying small molecules that bind metal ions. Metal ions are essential in biology. But identifying which molecules—and especially which small ...
