Summaries for GYS1 Gene

Entrez Gene Summary for GYS1 Gene

  • The protein encoded by this gene catalyzes the addition of glucose monomers to the growing glycogen molecule through the formation of alpha-1,4-glycoside linkages. Mutations in this gene are associated with muscle glycogen storage disease. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Sep 2009]

GeneCards Summary for GYS1 Gene

GYS1 (Glycogen Synthase 1) is a Protein Coding gene. Diseases associated with GYS1 include Glycogen Storage Disease 0, Muscle and Glycogen Storage Disease. Among its related pathways are Development IGF-1 receptor signaling and Glycogen storage disease type XV (GYG1). GO annotations related to this gene include protein kinase binding and glycogen (starch) synthase activity. An important paralog of this gene is GYS2.

UniProtKB/Swiss-Prot for GYS1 Gene

Post-translational modifications for GYS1 Gene

  • Phosphorylation at Ser-8 by AMPK inactivates the enzyme activity. Primed phosphorylation at Ser-657 (site 5) by CSNK2A1 and CSNK2A2 is required for inhibitory phosphorylation at Ser-641 (site 3a), Ser-645 (site 3b), Ser-649 (site 3c) and Ser-653 (site 4) by GSK3A an GSK3B (By similarity). Phosphorylated at Ser-641 by DYRK2, leading to inactivation (By similarity). Phosphorylated at Ser-641 by PASK, leading to inactivation; phosphorylation by PASK is inhibited by glycogen. Dephosphorylation at Ser-641 and Ser-645 by PP1 activates the enzyme.

Function for GYS1 Gene

Molecular function for GYS1 Gene

GENATLAS Biochemistry:
glycogen synthase,skeletal muscle,the rate limiting enzyme of the insulin-induced glycogenesis
UniProtKB/Swiss-Prot CatalyticActivity:
UDP-alpha-D-glucose + ((1->4)-alpha-D-glucosyl)(n) = UDP + ((1->4)-alpha-D-glucosyl)(n+1).
UniProtKB/Swiss-Prot EnzymeRegulation:
Allosteric activation by glucose-6-phosphate. Phosphorylation reduces the activity towards UDP-glucose. When in the non-phosphorylated state, glycogen synthase does not require glucose-6-phosphate as an allosteric activator; when phosphorylated it does (By similarity).
UniProtKB/Swiss-Prot Function:
Transfers the glycosyl residue from UDP-Glc to the non-reducing end of alpha-1,4-glucan.
