The AMP-activated protein kinase (AMPK) β1 (Phospho-Ser181) antibody is designed to detect the β1 subunit of AMPK when phosphorylated at serine 181. AMPK is a heterotrimeric enzyme critical for cellular energy homeostasis, composed of α (catalytic), β, and γ (regulatory) subunits. The β1 subunit (PRKAB1) serves as a scaffold, linking α and γ subunits, and contributes to subcellular localization and stability of the AMPK complex.
Phosphorylation at Ser181 in the β1 subunit is associated with regulatory mechanisms beyond AMPK’s canonical activation via α-subunit phosphorylation (Thr172). While the precise role of β1-Ser181 phosphorylation remains under investigation, studies suggest it may influence AMPK activity, substrate specificity, or interactions with binding partners. This modification has been implicated in metabolic processes, autophagy, and cellular stress responses.
The AMPK β1 (Phospho-Ser181) antibody is widely used in research to study AMPK signaling dynamics in conditions like metabolic disorders, cancer, and aging. It is validated for applications such as Western blotting, immunoprecipitation, and immunofluorescence. Specificity is confirmed using knockout controls or phosphatase-treated samples to ensure recognition of the phosphorylated epitope. Researchers employ this antibody to explore how Ser181 phosphorylation modulates AMPK’s role in energy sensing and disease pathways.
