FunctionActs as a glycogen-targeting subunit for phosphatase PP1. Facilitates interaction of the PP1 with enzymes of the glycogen metabolism and regulates its activity. Suppresses the rate at which PP1 dephosphorylates (inactivates) glycogen phosphorylase and enhances the rate at which it activates glycogen synthase and therefore limits glycogen breakdown. Its activity is inhibited by PYGL, resulting in inhibition of the glycogen synthase and glycogen phosphorylase phosphatase activities of PP1. Dramatically increases basal and insulin-stimulated glycogen synthesis upon overexpression in hepatocytes.
Tissue specificityHighly expressed in liver. Expressed moderately in skeletal muscle and myotubes (at protein level). Expressed predominantly in heart and skeletal muscle. Expressed moderately in liver. Expressed weakly in placenta, lung and kidney.
