Predicted to enable glycogen binding activity and protein phosphatase 1 binding activity. Predicted to be involved in regulation of glycogen biosynthetic process. Predicted to act upstream of or within glucose homeostasis; positive regulation of glycogen (starch) synthase activity; and positive regulation of glycogen biosynthetic process. Predicted to be located in cytoplasm. Predicted to be part of protein phosphatase type 1 complex. Orthologous to human PPP1R3G (protein phosphatase 1 regulatory subunit 3G).
