p-GSK-3α Antibody (9B8) is a mouse monoclonal IgG1 antibody that detects glycogen synthase kinase-3α (GSK-3α) in mouse, rat, human, and canine samples through applications such as western blotting (WB), immunoprecipitation (IP), and immunofluorescence (IF). anti-GSK-3α antibody (9B8) specifically recognizes the phosphorylated form of GSK-3α, which plays a crucial role in various cellular processes, including energy metabolism and neuronal cell development. GSK-3α (9B8) antibody targets proteins primarily located in the cytoplasm and nucleus, where GSK-3α regulates key signaling pathways that influence cell growth and survival. GSK-3α′s localization enables interaction with various substrates and signaling molecules, modulating their activity in response to extracellular signals. Nuclear presence of GSK-3α is essential for transcriptional regulation, particularly in cell proliferation and differentiation. Growth factors can influence GSK-3α′s phosphorylation state, which determines activity and protein interactions, highlighting the importance of cellular location in maintaining proper function. GSK-3α monoclonal antibody (9B8) provides valuable insights into regulatory mechanisms, making this antibody an invaluable tool for researchers studying metabolic pathways and signaling cascades in various biological contexts.
