    Designing protein molecules that will assemble into various kinds of ordered materials represents an important challenge in nanotechnology. We report the crystal structure of a 12-subunit protein cage that self-assembles by design to form a tetrahedral structure roughly 16 nanometers in diameter. The strategy of fusing together oligomeric protein domains can be generalized to produce other kinds of cages or extended materials.
