Researchers have confirmed that mammalian BK ion channels regulate themselves using a “ball-and-chain” mechanism. A recent ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function ...

Certain cells, commonly called excitable cells, are unique because of their ability to generate electrical signals. Although several types of excitable cells exist — including neurons, muscle ...

An acetylcholine receptor (green) forms a gated ion channel in the plasma membrane. This receptor is ... to flow into the cell. An excitable cell converts chemical or mechanical signals into ...

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a "ball-and-chain ...

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through ... these vesicles contain an ion channel—a protein that opens ...

Together, they measured the first Ach-activated single channel recording across a membrane patch of frog skeletal ... between biology using electricity. Every cell is like a battery and the ion ...

In plants, guard cells control the stomatal opening by expanding and contracting through ion flux. When a plant senses light, a signal is sent to the guard cell to increase its ... scientists to use ...

Researchers at the University of Chicago and Argonne National Laboratory have been working on this problem for years; now, together with partners from Harvard University, they have perfected a new ...

Ion channels are protein structures embedded in cell ... Currently, Dr. Nimigean and her team are investigating how ...

The BK ion channel pictured above forms a small pathway in the cell membrane (dark gray) that allows potassium ions (purple) to move in and out of the cell. This channel can stop the flow of ions ...

Ion channels are protein structures embedded ... team are investigating how fat-related molecules in the cell membrane can influence BK channel activity also.
