Phosphorylation of BAD, a pro-apoptotic member of the Bcl-2 protein family, on either serine 112 or serine 136 is thought to be necessary and sufficient for growth factors to promote cell survival (1–3). Serine 155 is a major site of phosphorylation by protein kinase A (PKA) and serum-induced kinases (1). Serine 155 phosphorylation requires the prior phosphorylation of serine 136, which recruits 14-3-3 proteins that then function to increase the accessibility of serine 155 to survival-promoting kinases (4). Like serine 112 and serine 136, phosphorylation of serine 155 inhibits the pro-apoptotic function of BAD (1). Serine 155 phosphorylation disrupts the binding of BAD to prosurvival Bcl-2 proteins and thereby promotes cell survival (4,5).
