Macrophage-expressed gene 1 (MPEG1) functions within the phagolysosome to damage engulfed microbes, presumably via forming pores in target membranes. In order to provide insights into the mechanism of MPEG1 function and membrane binding, the authors present structures of hexadecameric MPEG1 prepores both in solution and in complex with liposomes.
