Human muscle glycogen synthase (GS) is responsible for the biosynthesis of glycogen from phosphorylated glucose units. Mammalian liver and muscle contain GS consisting of four subunits with a total molecular weight of 360,000. GS is subject to regulation through both allosteric and covalent modification and occurs in two forms: the phosphorylated inactive form, and the dephos-phorylated active form. GS is inactivated by the serine/threonine kinase called glycogen synthase kinase-3b that mainly functions to phos-phorylate muscle glycogen synthase.Synonyms: GYS, GYS1, muscle Glycogen Synthase
