Cryo-EM reconstructions of KIX

Red molecules are sandwiched between a blue inner shell and purple outer shell.

Cryo-EM reconstructions of KIX (red) sandwiched between an MBP outer shell (purple) and an apoferritin inner shell (blue). The sandwiching technique helped researchers get the best look yet of KIX, a potential target for treating acute myeloid leukemia.
