Molecular engineers have now show that it is possible to build complex, custom-designed transmembrane proteins from scratch. In the living world, transmembrane proteins naturally occur embedded in the membranes of cells and cellular organelles. They are essential for a number of functions, such as movement of signals or substances from inside or outside a living cell. The ability to design synthetic proteins to span membranes could allow scientists to build ones that can perform specific, useful tasks.
