Additional sequence informationGYG1 Human Recombinant fused with a 32 amino acid His-T7 tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 365 amino acids (1-333 a.a.).
Additional notesGlycogenin 1 although stable 4°C for 4 weeks, should be stored desiccated below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

FunctionSelf-glucosylates, via an inter-subunit mechanism, to form an oligosaccharide primer that serves as substrate for glycogen synthase.
Involvement in diseaseDefects in GYG1 are the cause of glycogen storage disease type 15 (GSD15) [MIM:613507]. It is a metabolic disorder resulting in muscle weakness, associated with the glycogen depletion in skeletal muscle, and cardiac arrhythmia, associated with the accumulation of abnormal storage material in the heart. The skeletal muscle shows a marked predominance of slow-twitch, oxidative muscle fibers and mitochondrial proliferation.
Sequence similaritiesBelongs to the glycogenin family.
Post-translational modificationsSelf-glycosylated by the transfer of glucose residues from UDP-glucose to itself, forming an alpha-1,4-glycan of around 10 residues attached to Tyr-195. Phosphorylated.
