New York, NY - A toxin isolated from coral reefs has enabled US scientists to better understand exactly how the sodium/potassium ion pump works and may ultimately help them to design molecules to make ...
Right now, in your body, tiny pumps in the fatty membranes surrounding all your cells are hard at work pushing select charged ions, such as sodium, potassium or calcium, through those membranes. Like ...
The structure of the sodium-potassium pump is presented in a schematic cell membrane. The extracellular space is situated above and the intracellular space below the figure. The left-hand side of the ...
Scientists have uncovered the atomic structure of KR2, a light-driven transporter for sodium ions which had only recently been discovered. Based on the structural information the team then identified ...

How cells power their molecular highways
Active transport is the cell’s way of moving molecules against the flow, using energy to keep life running smoothly. From sodium-potassium pumps to bulk transport, these processes maintain balance and ...
Hemiplegia, the paralysis of one side of the body, is a clinical manifestation observed in various neurological disorders. In several cases, the underlying aetiology involves dysfunction of the Na+/K+ ...
Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles ...
