Enables deacetylase activity and sulfotransferase activity. Predicted to be involved in heparan sulfate proteoglycan biosynthetic process, polysaccharide chain biosynthetic process. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. Is expressed in several structures, including nervous system. Orthologous to human NDST4 (N-deacetylase and N-sulfotransferase 4). [provided by Alliance of Genome Resources, Apr 2022]
