    Protein/Peptide Type
    Biologically Active Protein
    Gene
    GSK3B
    Purity
    >90%, by SDS-PAGE

Applications/Dilutions

    Application Notes
    Specific activity: Activity of GSK-3B was determined by an in vitro kinase assay using 100 ng Tau as substrate and 1 ug of the recombinant GSK-3B in a 20 ul reaction containing 25 mM Tris-HCl, pH 7.5, 5 mM B-glycerol phosphate, 12 mM MgCl2, 2 mM DTT, 0.1 M Na3VO4, and 200 uM ATP. After 30 minutes incubation at 30C, phosphorylation of Tau by the recombinant GSK-3B was determined by Western blot using a phospho-Tau antibody.
    Theoretical MW
    54.5 kDa.
    Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background

Glycogen synthase kinase-3 (GSK-3) is a serine/theronine kinase that was first characterized by its role in intermediary metabolism. In mammals, serine kinase is encoded by two related genes called GSK-3alpha (51 kDa) and GSK-3Beta (46 kDa). GSK-3 has been implicated in the regulation of the c-Jun/AP-1 transcription factor and other intracellular signaling pathways.
