Protein-protein interactions are critical for cell life. One aspect of cellular regulation where such protein-protein interactions occur is in the highly regulated process of programmed cell death (or apoptosis). Apoptosis is critical for normal tissue homeostasis, differentiation, and if dysregulated is a driver of disease including cancers. At the center of apoptotic regulation is the BCL2 protein family whose intra-familial protein-protein interactions balance cell stress signaling either allowing the cell to survive or inducing mitochondrial cell death. These BCL2 protein interactions are accomplished through the BH3 motif. While unique to the BCL2 family, a similar motif, the reverse BH3, has …
