In this work, we have determined the three-dimensional structure of the NINJ1 filament. This filament ruptures the eukaryotic plasma membrane at the endpoint of pyroptosis and other cell deaths. The structure of the NINJ1 filament explains how NINJ1 monomers form a tightly packed arrays of transmembrane α-helices, and how their amphipathic surface allows them to rupture the membrane.
