The proapoptotic protein Bax triggers cell death by forming pores in the outer mitochondrial membrane. Using single-particle TIRF imaging, the authors show that Bax binds the membrane in a monomeric state before forming dimers and multimers of dimers, which are disassembled by the survival protein Bcl-xL.
