    Protocol

    Specificity / Sensitivity

    Phospho-GSK-3β (Thr390) Antibody detects endogenous levels of human GSK-3β protein only when phosphorylated at Thr390.

    Species Reactivity:

    Human

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr390 of human GSK-3β. Antibodies are purified by 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).
    The phosphorylation of GSK-3β at Thr390 was found to be a possible substrate of p38 MAPK and was reported by several labs using phosphoproteomic analysis on mitotic cell extracts (6-10). Phosphorylation of this site was also identified at Cell Signaling Technology (CST) using PhosphoScan®, CST's LC-MS/MS platform for modification site discovery (11).
