    Product Usage Information

    Application Dilution
    Western Blotting 1:1000

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    Phospho-GSK-3alpha/beta (Ser21/9) Antibody detects endogenous levels of GSK-3 only when phosphorylated at serine 21 of GSK-3alpha or serine 9 of GSK-3beta.

    Species Reactivity:

    Human, Mouse, Rat, Monkey, Zebrafish

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with synthetic phosphopeptides corresponding to the sequences of human GSK-3 alpha and beta. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Glycogen synthase kinase-3 (GSK-3) was initially identified as an enzyme that regulates glycogen synthesis in response to insulin (1). GSK-3 is a ubiquitously expressed serine/threonine protein kinase that phosphorylates and inactivates glycogen synthase. GSK-3 is a critical downstream element of the PI3K/Akt cell survival pathway whose activity can be inhibited by Akt-mediated phosphorylation at Ser21 of GSK-3α and Ser9 of GSK-3β (2,3). GSK-3 has been implicated in the regulation of cell fate in Dictyostelium and is a component of the Wnt signaling pathway required for Drosophila, Xenopus, and mammalian development (4). GSK-3 has been shown to regulate cyclin D1 proteolysis and subcellular localization (5).
