Without hands or feet, a single human cell has little to protect itself from surrounding threats like bacteria or viruses. In this way, the cell membrane has evolved to be much more than a wall that keeps cell content inside and everything else outside. By dynamically changing its shape, the membrane allows the cell to purge itself of waste and also attack nearby threats. Japanese scientists now report how the assembly of the protein Growth Arrest Specific 7 (GAS7) into two-dimensional sheets is crucial for this second process.
