STUDY: Engineered protein crystals make cells magnetic – American Chemical Society

To drastically increase the amount of iron that a protein assembly can store, Bianxiao Cui and colleagues wanted to combine the iron-binding ability of ferritin with the self-assembly properties of another protein, called Inkabox-PAK4cat, that can form huge, spindle-shaped crystals inside cells. The researchers wondered if they could line the hollow interiors of the crystals with ferritin proteins to store larger amounts of iron that would generate substantial magnetic forces.
