GSK-3β, His•Tag^®, Human, Recombinant, E. coli

Recombinant, human GSK-3β fused at the N-terminus to a His•Tag sequence and expressed in E. coli. Glycogen synthase kinase-3 (GSK-3) is a serine/threonine kinase that was first characterized by its role in intermediary metabolism. GSK-3β is a dual-specificity kinase that is important role in insulin- and Wnt-mediated cellular signaling events. In Alzheimer′s disease GSK-3β is reported to affect microtubule stability via the phosphorylation of microtubule associated protein, Tau. Other known substrates include glycogen synthase, p90^rsk, c-Jun, and CREB. MW: 53,000-56,000

1 µg GSK-3β maximally phosphorylates 100 ng Tau protein in 30 min in an in vitro kinase assay at 30°C, pH 7.5
