Phospho-GSK-3α (Ser21) (27E5) Mouse mAb #5090
Gallery: Phospho-GSK-3α (Ser21) (27E5) Mouse mAb #5090
Phospho-GSK-3alpha (Ser21) (27E5) Monoclonal Antibody can be used in high throughput kinase assays and drug discovery applications. It detects peptides derived from GSK-3alpha phosphorylated at Ser21.
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Ser21 of human GSK-3alpha. Antibody is purified using protein G affinity chromatography.
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).
