BH3-only proteins are structurally distant members of the Bcl-2 protein family that trigger apoptosis. Genetic experiments have shown that these proteins are essential initiators of programmed cell death in species as distantly related as mice and C. elegans. BH3-only proteins share with each other and with the remainder of the Bcl-2 family only a nine amino acid BH3 (Bcl-2 Homology) region. Mutational analyses have demonstrated that this domain is required for their ability to bind to Bcl-2-like pro-survival proteins and to initiate apoptosis. So far only one BH3-only protein, EGL-1, has been identified in C. elegans and it is required for all developmentally programmed death of somatic cel..
