Specificity / Sensitivity
Phospho-GSK-3beta (Ser9) Antibody detects endogenous levels of GSK-3β only when phosphorylated at serine 9. The antibody may cross-react weakly with the phosphorylated form of GSK-3α due to high sequence homology.
Species Reactivity:
Human, Mouse, Rat, Monkey
The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.
Species predicted to react based on 100% sequence homology:
Zebrafish, Bovine
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to the sequence of human GSK-3β. 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).
