A less-fluid cell membrane

Nancy D. Lamontagne

Scientists once thought of the cell membrane as a fluid structure comprising freely moving proteins. However, as methods to label and track proteins emerged, it became clear that membranes contain areas with restricted protein diffusion. Since this discovery, how and why diffusion is restricted in certain areas has been the subject of many studies. Now researchers at the University of New Mexico and at Sandia National Laboratories, both in Albuquerque, have produced images of the action taking place in these areas of restricted diffusion. The investigators, led by Diane Lidke, labeled...Read full article
