Cells rely on membranes to protect themselves from the outside world. But cell membranes can't be fully closed because nutrients and other molecules have to be able to pass through. To achieve this, cell membranes have many types of channels and pores. Also, there are receptors embedded in the membrane that continuously monitor the outside world and signal to the cell interior. Extensive collaboration between five VIB groups resulted in a better understanding of the machinery that plants use to regulate the protein composition of their outer membrane. This discovery, published in Science Advances, enhances our basic knowledge of how the plasma membrane composition can be adapted based on external stimuli, an essential process for life on earth.
