Skurat A, Dietrich A, Roach P. Glycogen synthase sensitivity to insulin and glucose-6-phosphate is mediated by both NH2- and COOH-terminal phosphorylation sites. Diabetes. 2000;49:1096-100 pubmed
..In Rat-1 fibroblasts, GSK-3 action is not essential for glycogen synthase activation by insulin, and GSK-3-independent mechanisms also operate. ..
Skurat A, Dietrich A. Phosphorylation of Ser640 in muscle glycogen synthase by DYRK family protein kinases. J Biol Chem. 2004;279:2490-8 pubmed
..The inactivation correlated with phosphorylation of site 3a in glycogen synthase. These results indicate that protein kinase(s) from the DYRK family may be involved in a new mechanism for the regulation of glycogen synthesis. ..
Skurat A, Dietrich A, Roach P. Interaction between glycogenin and glycogen synthase. Arch Biochem Biophys. 2006;456:93-7 pubmed
..We demonstrate that the COOH-terminal fragment of glycogenin can be used as an effective high affinity reagent for the purification of glycogen synthase from skeletal muscle and liver. ..
