Predicted to enable N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase activity. Acts upstream of or within secretion of lysosomal enzymes. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Is expressed in thymus primordium. Orthologous to human NAGPA (N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase). [provided by Alliance of Genome Resources, Apr 2022]
