General description

A cell-permeable myristoylated form of GSK-3β Peptide Inhibitor (Cat. No. 361545) with a glycine spacer. Acts as a selective, substrate-specific, competitive inhibitor of GSK-3β (IC50 = 40 µM). Does not affect the activities of Cdc2, PKB, and PKC. Shown to mimic insulin action, and activate glycogen synthase activity (~2.5-fold) in HEK293 cells and improve glucose tolerance in diabetic mice. Displays in vivo stability.
