The Bcl-2 family consists of a number of evolutionarily conserved proteins containing Bcl-2
homology domains (BH) that regulate apoptosis through control of mitochondrial membrane permeability and release of cytochrome c (1-3). Four BH domains have been identified (BH1-4), which mediate protein interactions. The family can be separated into three groups
based upon function and sequence homology: pro-surivival members including Bcl-2, Bcl-xL, Mcl-1, A1, and Bcl-w; pro-apoptotic proteins including Bax, Bak, and Bok; and “BH3 only” proteins Bad, Bik, Bid, Puma, Bim, Bmf, Noxa, and Hrk. Interactions between death-promoting
and death-suppressing Bcl-2 family members has led to a rheostat model in which the ratio of pro-apoptotic and anti-apoptotic proteins controls cell fate (4). Thus, pro-survival members exert their behavior by binding to and antagonizing death-promoting members. In general, the “BH3-only members” can bind to and antagonize the pro-survival proteins leading to
increased apoptosis (5). While some redundancy of this system likely exists, tissue specificity and transcriptional and post-translational regulation of many of these family members can account for distinct physiological roles. Several phosphorylation sites have been identified within
Bcl-2 including Thr56, Ser70, Thr74, and Ser87 (6).
