背景信息

The PFKFB2 (Phospho-Ser466) antibody is a specialized tool used to detect the phosphorylated form of PFKFB2 (6-phosphofructo-2-kinase/fructose-2.6-biphosphatase 2) at serine residue 466. PFKFB2 is a bifunctional enzyme critical for regulating glycolysis and gluconeogenesis by controlling cellular levels of fructose-2.6-bisphosphate (F2.6BP), a potent allosteric activator of phosphofructokinase-1 (PFK-1). Phosphorylation at Ser466. often mediated by AMP-activated protein kinase (AMPK) or protein kinase A (PKA), enhances PFKFB2's kinase activity, promoting F2.6BP synthesis and glycolysis. This post-translational modification is tightly linked to cellular energy status and stress responses. The antibody enables researchers to study dynamic changes in PFKFB2 activity under conditions such as hypoxia, nutrient deprivation, or metabolic disorders. It is widely used in techniques like Western blotting, immunofluorescence, and immunoprecipitation to assess phosphorylation-dependent regulatory mechanisms in metabolic pathways. Dysregulation of PFKFB2 phosphorylation has been implicated in diseases like cancer, diabetes, and cardiovascular disorders, making this antibody valuable for investigating metabolic reprogramming in pathological contexts. Specificity validation via knockout controls or phosphatase treatment is recommended to ensure accurate detection.
