Article: PHOSPHOLIPIDS IN CELL MEMBRANE HELP REGULATE ION CHANNELS

Rockefeller University issued the following press release:

Though the cell membrane is a protective barrier, it also plays a role in letting some foreign material in via ion channels that dot the cell's surface. Now new research from the Nobel Prize-winning laboratory that first solved the atomic structure of several such channels shows that their function is controlled in part by a complex interaction between a channel's voltage sensor and the cell membrane immediately adjacent to it.

The cell membrane is a specialized environment, home to a variety of proteins that enable the cell to interact with its environment. One specific family of proteins, voltage-gated channels, are especially ...
