- Glycogen Synthase Kinase-3 (GSK-3) is a serine/threonine kinase that was first characterized by its role in intermediary metabolism. The enzyme is the mammalian homolog of the zeste-white3 (shaggy) homeotic gene of Drosophila melanogaster and has been implicated in the regulation of the c-Jun/AP-1 transcription factor. Genetic and biochemical evidence now indicates that GSK-3 plays a role in intracellular signaling pathways. For example, during insulin and growth factor signaling the GSK-3 beta isoform becomes phosphorylated on its N-terminal serine-9 residue, presumably by either the action of MAPKAP Kinase-1 (p90 S6 kinase, Rsk-2) or p70 S6 kinase. Such phosphorylation of GSK-3 blocks its ability to phosphorylate c-Jun, protein phosphatase inhibitor 2 or the GSK-3 substrate peptide. GSK-3 is constitutively phosphorylated at this tyrosine residue in resting cells. This immunogen is identical in 15 of 17 residues in human and rat GSK-3a (Y279) and GSK-3b (Y216). The phosphotyrosine residue can be removed from GSK-3 by treatment with PTP1B. Applications: Suitable for use in Western Blot. Not suitable for use in Immunoprecipitation. Other applications have not been tested. Recommended Dilutions: Western Blot: 0.5-2ug/ml detects phospho-GSK-3 in RIPA lysates from human Jurkat cells. Previous lots detected phospho-GSK-3 in mouse 3T3/A31, human A431 and rat L6 cell lysates. Jurkat cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with G8170-47. Proteins were visualized using an IgG (HRP) goat anti-mouse and a chemiluminescence detection system Optimal dilutions to be determined by the researcher. Included Positive Antigen Control: J9000: Jurkat lysate. Use 20ug per lane for minigels. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
