Cells are compartmentalized by membranes, and proteins present in these membranes play an important role in transporting cellular information. For proper function of these proteins to occur, a tertiary protein structure must be formed through the correct folding process. In a study published in Nature Chemical Biology, the folding process of a glucose transporter—a complex membrane protein—was identified for the first time using single-molecule magnetic tweezers.
