General description

Glycogen synthase kinase 3 (GSK3) is a proline directed serine threonine kinase that was initially identified as a phosphorylating and inactivating glycogen synthase, a key enzyme in glycogen metabolism. Since then, it has been shown to be involved in the regulation of a diverse array of cellular functions, including protein synthesis, cell proliferation, cell differentiation, microtubule assembly/disassembly, and apoptosis.
There exists two isoforms of GSK3, alpha and beta, and they show a high degree of amino acid homology. The two isoforms of GSK3 are strictly regulated via phosphorylation. Activation of GSK3 beta is dependent upon the phosphorylation of Tyr216 (Tyr279 in GSK3 alpha). Upon activation, it has been shown to phosphorylate a number of different cellular proteins, including p53, c-Myc, c-Jun, heat shock factor 1 (HSF1), and cyclin D1

Specificity

Predicted to react with GSK-3 orthologs from drosophila melanogaster and many other species based on sequence homology surrounding the target phosphotyrosine residue.
Recognizes GSK-3 phosphorylated at the target tyrosine residue (human GSK-3α pY279 and GSK-3β pY216). The 17-amino acid immunogen peptide sequence differs from the corresponding human, mouse, and rat sequence by only two amino acid residues.

Immunogen

Epitope: Surrounding pTyr214 (Drosophila GSK-3), pTyr279 (human GSK3α), pTyr216 (human GSK3β)
Synthetic peptide (C-KQLLHGEPNVS[pY]ICSRY) corresponding to amino acids 203-219 derived from a region of the catalytic domain (between subdomain VII and VIII) of the Drosophila GSK3/shaggy enzyme coupled to ovalbumin.
