Glycogen Synthase Kinase 3 differs from most serine/threonine kinases in that it is active in the absence of the action of signaling pathways. Two isoforms exist, GSK3α and GSK3β. The function of GSK3 is to phosphorylate Glycogen Synthase and thereby inactivate it. Insulin action stimulates the PI3 Kinase pathway, resulting in Akt activation, which phosphorylates and inactivates GSK3. Glycogen Synthase is then rapidly dephosphorylated and activated. Other GSK3 substrates include Jun (on inhibitory sites), and eIF2B. Phosphorylation of Tau by GSK3 may relate to development of Alzheimer's disease. Phosphorylation state-specific antibodies directed against the Akt site (Ser21) on GSK3 are suitable for surrogate assays of the activation state of the pathway.
This Anti-GSK3α/β Antibody is validated for use in WB, IP for the detection of GSK3α/β.

Glycogen synthase kinase 3-alpha (GSK3A; EC {2.7.1.37}) is a multifunctional protein serine kinase,
homologous to Drosophila 'shaggy' (zeste-white3) and implicated in the control of
several regulatory proteins including glycogen synthase (see GYS1, {138570}) and transcription
factors (e.g., JUN, {165160}). It also plays a role in the WNT ({164820}) and PI3K (see PIK3CG, {601232}) signaling pathways (see review by {1:Ali et al. (2001)
FUNCTION:Implicated in the hormonal control of several regulatory proteins including glycogen synthase, MYB and the transcription factor JUN By similarity. CATALYTIC ACTIVITY:ATP + [tau protein] = ADP + [tau protein] phosphate. SUBUNIT STRUCTURE:Monomer By similarity. SEQUENCE SIMILARITIES:Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. GSK-3 subfamily.
Contains 1 protein kinase domain.
