Predicted to enable glycogen binding activity and protein phosphatase 1 binding activity. Predicted to contribute to phosphoprotein phosphatase activity. Predicted to be involved in regulation of glycogen biosynthetic process and regulation of glycogen catabolic process. Predicted to be located in glycogen granule and intracellular membrane-bounded organelle. Predicted to be part of protein phosphatase type 1 complex. Orthologous to human PPP1R3D (protein phosphatase 1 regulatory subunit 3D). [provided by Alliance of Genome Resources, Apr 2022]
