The cells of living organisms are equipped with proteins that are involved in the shaping and remodeling of cellular membranes, thereby performing important tasks. The cell membrane encloses the cell interior, but is constantly remodeled, for example, due to membrane budding, invagination, or fusion processes. This also involves various proteins that were long assumed to be present exclusively or predominantly in higher organisms. In the past 10 to 20 years, however, proteins have been identified or predicted to be present also in simple organisms that do not possess a nucleus. In a research collaboration, a protein involved in membrane remodeling in cyanobacteria has now been described for the first time. The existence of such a bacterial protein was suspected, but proof was still pending. The studied protein is likely a bacterial representative of a similar protein found in higher organisms such as animals and plants.
