Western blot - Anti-Glycogen synthase 1/GYS1 (phospho S641) antibody (AB2479)
Rabbit polyclonal to phospho Glycogen Synthase (Ser 640) used at a 1/1000 dilution to detect human muscle GS by Western blot. Approximately 12 ul of a mouse cardiac myocyte lysate was loaded per lane on a 4-20% Criterion gel for SDS-PAGE. Samples were either mock treated (lanes 1 and 5) or insulin treated at 10 nM, 100 nM and 1 mM (lanes 2, 3 and 4 respectively) for 15' or CLA treated at 4nM, 20 nM or 100 nM (lanes 6,7 and 8 respectively) for 45'.
Goat polyclonal to rabbit IgG (HRP) (ab7090) was used as secondary antibody at 1/5000.
A 4-20% Criterion gel for SDS-PAGE was used.

Biological function summary
This enzyme plays a critical role in the energy storage mechanism of muscle tissues. GYS1 functions as a part of the glycogen synthase complex interacting with various glycogen-associated proteins to modulate its activity. These interactions control the enzyme's affinity for its substrate and its susceptibility to regulatory signals like phosphorylation affecting glycogen synthesis efficiency. Through its activity GYS1 ensures a readily available reserve of glucose in muscle tissues for rapid energy production when required.
Pathways
Glycogen synthase 1 is a central component of the glycogen metabolism pathway. It acts alongside other enzymes such as glycogen phosphorylase which catalyzes glycogen breakdown. The balance between GYS1 and glycogen phosphorylase determines the rate of glycogen turnover within cells. GYS1 is further regulated by the insulin signaling pathway where insulin promotes glycogen synthesis by altering GYS1 activity alongside proteins like AKT influencing glucose homeostasis and energy management in tissues.
