Pig
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the sequence of human GSK-3α protein.
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).
GSK-3α regulates the production of amyloid-β peptides, a major component of the plaques that accumulate with progression of Alzheimer disease. Administration of therapeutic concentrations of lithium, a GSK-3 inhibitor, attenuates amyloid-β production by specifically inhibiting the cleavage of amyloid precursor protein (APP) by γ-secretase, blocking accumulation of amyloid-β peptides in the brains of mice that overproduce APP (6).
