Recombinant Human GSK-3 beta Protein (Baculovirus-Insect, His Tag)

Biological Activity

GSK-3 beta/GSK3B Protein is a serine-threonine kinase, belonging to the glycogen synthase kinase subfamily. GSK3B participates in the Wnt signaling pathway. It is implicated in the hormonal control of several regulatory proteins including glycogen synthase, MYB, and the transcription factor JUN. GSK3B also plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex. It prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane. GSK3B phosphorylates MACF1 and this phosphorylation inhibits the binding of MACF1 to microtubules which are critical for its role in bulge stem cell migration and skin wound repair.

The recombinant human GSK3B consists of 452 amino acids and predicts a molecular mass of 50.4 kDa. It expressed the target gene encoding (Met 1-Thr 433) with a polyhistidine tag at the N-terminus.

Immobilized His-GSK3B at 10 μg/ml (100 μl/well) can bind biotinylated human HG3C-CTNNB1, EC50 of biotinylated human HG3C-CTNNB1 is 0.15-0.35 μg/ml.
