Immunogen:
The antiserum was produced against a chemically synthesized phosphopeptide derived from the region of human Glycogen Synthase that contains serine 641 and serine 645. The sequence is conserved in human, mouse and rat.
Application Western Blot, The antibody has been used for Western blotting. No other applications have been tested. Recommended starting dilutions: Western Blot - 1:1000 *The optimal antibody concentration should be determined empirically for each specific application. , Western Blot
Background Glycogen Synthase (GS), is an 85 kDa protein and a key enzyme in regulating glycogen synthesis by catalyzing the rate-limiting step of UDP-glucose incorporation into glycogen. The activity of glycogen synthase is regulated by hormonal stimuli (insulin, catecholamines and glucagons) and non-hormonal stimuli (blood glucose level and exercise). Muscle glycogen synthase is phosphorylated on at least nine sites by multiple kinases including glycogen synthase kinase-3 (GSK-3), mitogen-activated protein kinase-related protein kinase (DYRK), and SAPK2b/p38b which leads to its inactivation. GSK-3 phosphorylates glycogen synthase at four serine sites in the COOH terminus including serines 641 and 645. Serine 641 is also phosphorylated by DYRK, while serine 645 is phosphorylated efficiently by SAPK2b/p38b. SAPK2b/p38b is believed to represent a priming kinase that allows GSK-3 to phosphorylate glycogen synthase at serine 641 and therefore inhibits its activity.
