Glycogen synthase is directly regulated by glycogen synthase kinase 3 (GSK-3), AMPK, protein kinase A (PKA), and casein kinase 2 (CK2). Each of these protein kinases lead to phosphorylated and catalytically inactive glycogen synthase. The phosphorylation sites of glycogen synthase are summarized below. Abstract.

Glycogen synthase kinase 3 (GSK-3) is implicated in multiple biological processes including metabolism, gene expression, cell fate determination, proliferation, and survival. GSK-3 activity is inhibited through phosphorylation of serine 21 in GSK-3α and serine 9 in GSK-3β. Inactivation of glycogen synthase kinase-3beta (GSK3beta) by S(9) phosphorylation is implicated in mechanisms of neuronal survival.

The neural control of glycogen metabolism is mediated by calcium ions and involves phosphorylase kinase, and a specific calmodulin-dependent glycogen synthase kinase. The β-adrenergic control of the system is mediated by cyclic AMP, and involves the phosphorylation of phosphorylase kinase, glycogen synthase and inhibitor 1 by cyclic-AMP-dependent protein kinase.

Insulin promotes dephosphorylation and activation of glycogen synthase (GS) by inactivating glycogen synthase kinase (GSK) 3 through phosphorylation.

The β-adrenergic control of the system is mediated by cyclic AMP, and involves the phosphorylation of phosphorylase kinase, glycogen synthase and inhibitor 1 by cyclic-AMP-dependent protein kinase. Phosphorylation of glycogen synthase by insulin is dysregulated in skeletal muscle of obese subjects and patients with type 2 diabetes, leading to impaired glycogen synthase activation.

Activation of glycogen synthase occurs by dephosphorylation at sites phosphorylated by cAMP-dependent kinase and GSK-3. Protein phosphatase-l is a key component of the insulin signaling pathway and it activates glycogen synthase; it simultaneously inactivates phosphorylase a and phosphorylase kinase, promoting glycogen synthesis.

Phosphorylation of a distinct site, Y(216), on GSK3beta is necessary for its activity; however, whether this site can be regulated in cells is unknown. Glycogen synthase kinase 3 (GSK-3), a ubiquitously ex-pressed and evolutionarily conserved protein seriney threonine kinase, was originally identified as an enzyme that regulates glycogen synthesis in response to insulin (1). More recent studies implicate GSK-3 in multiple biological pro-cesses. GSK-3 phosphorylates a broad range of substrates, Glycogen synthase, a key enzyme in the regulation of glycogen synthesis by insulin, is controlled by multisite phosphorylation. Glycogen synthase kinase-3 (GSK-3) phosphorylates four serine residues in the COOH termi-nus of glycogen synthase. Phosphorylation of one of these residues, Ser640 (site 3a), causes strong inactiva-tion of glycogen synthase.
