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],GSY, GYS,AMPK Signaling Pathway,Cancer,Carbohydrate metabolism,Cardiovascular,Cardiovascular diseases,Cardiovascular diseases_Heart disease,Cell Biology & Developmental Biology,Cytoskeleton,Cytoskeleton_Actins,Endocrine & Metabolism,Endocrine and metabolic diseases,Endocrine and metabolic diseases_Diabetes,Endocrine and metabolic diseases_Obesity,Heart,Insulin Receptor Signaling Pathway,PI3K-Akt Signaling Pathway,Protein phosphorylation,Signal Transduction,GYS1
