... a compelling hypothesis of how the coordination of sodium may be affecting this particular type of potassium ion channel to open it," said Diomedes Logothetis, Ph.D., an internationally recognized ...
Researchers have uncovered how sodium is able to control specific potassium ion channels in cells, according to new study findings published online in Nature Chemical Biology.
... , or touch. Under certain forces, a channel opens, allowing the flow of ions, such as calcium and potassium ions, into and out of the cell. Different forces might close the channel, stopping the flow. ...
... HERG gene is affected.
Scientists discovered that both models selectively eliminated their respective potassium ion channels, leading to a significant prolongation of the QT interval. However, this ...
... channel, a membrane protein that responds to spikes of electricity by changing shape to allow potassium ions to enter a cell. This work has the potential to help us understand and control certain ...
... the researchers examined two channels that allow potassium ions to cross the cell membrane. The researchers genetically engineered mice to have defects in the ion channels Kv3.1 and Kv3.3, which ...
When it comes to sex, a female rat knows how to avoid a communication breakdown. To announce her sexual readiness, she will automatically arch her back, deflect her tail and stand rigid to allow an ...

... and sporadic cases of epilepsy."
The BK channel allows electrically charged potassium ions into and out of cells. This activity starts and stops the electrical impulses by which neurons communicate ...
... findings appear this week in the journal Neuron.
Ion channels belong to a special class of proteins ... sensor segment in a specific ion channel called the Shaker potassium channel. This protein was first ...
... ’s normal, “rest” state, this membrane actively sorts sodium ions to the outside of the cell and potassium ions to the inside. To transmit a nerve impulse, an electrochemical change ripples down the ...
... the Sleepless gene encodes a protein that affects whether potassium ion channels in the brain stay open or closed. When the channels are open, the brain is connected and working – ...
... a natural bee toxin on inward-rectifier potassium channels, Kir channels for short, to identify new ... , called tertiapin, or TPN, stops the flow of potassium ions across cell membranes by plugging up ...
... membrane causing sodium ions to flow in and potassium ions to flow out. The ion swap increases ... close and alternate paths open to “pump” the ions back to their initial concentrations during a “resting ...
... organisms spend a lot of energy pumping calcium and sodium out of cells and pumping potassium in."
Computer simulations and quantum calculations of how sodium and potassium bind to proteins were ...
