Glycogen synthetase
WebApr 1, 2001 · Glycogen synthesis in skeletal muscle is under hormonal control, with a principal regulatory role being taken by insulin that acutely promotes glycogen synthesis from glucose by stimulating glucose uptake and by activating the key enzyme glycogen synthase (GS) ().Stimulation of GS by insulin primarily involves net dephosphorylation of … WebGlycogen synthase kinase 3 (GSK3) was identified over 20 years ago as a protein kinase that phosphorylated and inhibited glycogen synthase [1 ], the enzyme that catalyzes the transfer of glucose from UDPG to glycogen. Subsequently, two separate isoforms were cloned, termed GSK3α and GSK3β [ 2 ]. These enzymes have extremely similar catalytic ...
