GSK3 (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 antibody detects a strong 47 kDa protein.

This antibody detects a strong 47 kDa protein, corresponding to the expected molecular mass of GSK3 beta.

Epitope: a.a. 335-349

Rat GSK3 beta synthetic peptide (aa. 335-349), conjugated to KLH. This sequence is 100% identical to human GSK3 beta.

Immunoprecipitation: 12.5 µg/mL dilution of a previous lot was ued in immunoprecipitation on rat brain tissue; immunoprecipitations with tissue extracts other than brain may require higher antibody concentrations.
Optimal working dilutions must be determined by the end user.

Immunohistochemistry(paraffin):
Representative testing from a previous lot.
