Protocol
Specificity / Sensitivity
Phospho-GSK-3alpha/beta (Ser21/9) (37F11) Rabbit mAb preferentially detects endogenous levels of GSK-3α when phosphorylated at Ser21 and also detects GSK-3β when phosphorylated at Ser9.
Species Reactivity:
Human, Mouse, Rat, Monkey
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues around Ser21 of human GSK-3α.
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).
