Researchers discover a new mechanism that deforms cell membranes

Cell membranes are very elastic. They can become distorted when they are asked to do so, when the cell divides, or when a virus detaches itself from the cell. In both cases, the membrane is deformed by a protein complex called ESCRT-III. Up until now, we did not understand how this complex works. Swiss and French researchers say that this protein complex forms a molecular spring at the surface of the cell, and operates like a watch spring. This article was published in Cell.
