BAD (Bcl2 agonist of cell death) is a member of the Bcl-2 family. Bcl-2 family members are known to be regulators of programmed cell death. This protein positively regulates cell apoptosis by forming heterodimers with Bcl-xL and Bcl-2, and reversing their death repressor activity. Proapoptotic activity of this protein is regulated through its phosphorylation. Protein kinases AKT and MAP kinase, as well as protein phosphatase calcineurin were found to be involved in the regulation of this protein [taken from NCBI Entrez Gene (GeneID:572)].
