The BAD (Bcl-2-associated death promoter) protein is a pro-apoptotic member of the BCL-2 family that regulates programmed cell death by interacting with anti-apoptotic proteins like BCL-2 or BCL-XL. Its activity is tightly controlled by phosphorylation at specific serine residues, including Ser91 and Ser128. Phosphorylation at these sites, mediated by survival signaling pathways such as those involving AKT, PKA, or RSK, inhibits BAD’s pro-apoptotic function by promoting its dissociation from anti-apoptotic partners and sequestering it in the cytoplasm via 14-3-3 scaffold proteins. This post-translational modification serves as a critical switch, linking extracellular survival signals to intracellular apoptotic machinery.
The Phospho-Ser91/128 antibody is a specialized tool used to detect BAD phosphorylated at these regulatory sites. It enables researchers to study the activation status of survival pathways in response to stimuli like growth factors, stress, or therapeutic agents. This antibody is widely applied in Western blotting, immunofluorescence, and immunohistochemistry to investigate cellular responses in contexts such as cancer, neurodegeneration, or metabolic disorders, where dysregulated apoptosis contributes to disease progression.
By targeting phosphorylation-specific epitopes, the antibody provides insights into dynamic signaling events that balance cell survival and death. Its specificity is validated through knockout/knockdown controls or phosphatase treatment to ensure accurate detection. Understanding BAD phosphorylation dynamics aids in exploring therapeutic strategies targeting apoptosis pathways, particularly in diseases with disrupted cell death regulation.
