Phospho-TSC2 (S1420) antibody is a specialized tool used to detect the phosphorylation status of tuberous sclerosis complex 2 (TSC2) at serine residue 1420. TSC2. encoded by the TSC2 gene, forms a heterodimeric complex with TSC1 to function as a critical regulator of the mTORC1 signaling pathway. This complex acts as a GTPase-activating protein (GAP) for Rheb (Ras homolog enriched in brain), thereby inhibiting mTORC1 activity under nutrient- or energy-deficient conditions. Phosphorylation of TSC2 at S1420. along with other sites, modulates its function, often in response to growth factors, cellular stress, or energy status. For instance, Akt, ERK, or AMPK may phosphorylate TSC2 at this site, altering its subcellular localization, stability, or interaction with other proteins, ultimately influencing mTORC1 signaling.
The Phospho-TSC2 (S1420) antibody is widely employed in research to study mTOR pathway dynamics, particularly in contexts like cancer, metabolic disorders, and autophagy. It helps assess the activation status of upstream regulators (e.g., growth factor receptors) and downstream effects on cell growth, proliferation, and survival. This antibody is validated for applications such as Western blotting, immunoprecipitation, and immunofluorescence, often using cell lysates from treated or genetically modified systems. Researchers use it to explore therapeutic responses, identify biomarkers, or dissect signaling crosstalk in diseases linked to mTOR dysregulation, such as tuberous sclerosis complex, diabetes, or neurodegenerative conditions. Proper controls (e.g., phosphorylation-deficient mutants) are essential to ensure specificity in experiments.
