Predicted to enable several functions, including [phosphorylase] phosphatase activity; 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. Predicted to act upstream of or within 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. Is expressed in several structures, including alimentary system; hindlimb mesenchyme; respiratory system; sensory organ; and urinary system. Orthologous to human PPP1R3B (protein phosphatase 1 regulatory subunit 3B). [provided by Alliance of Genome Resources, Apr 2022]
