Predicted to enable 3'-phosphoadenosine 5'-phosphosulfate binding activity and N-acetylgalactosamine 4-sulfate 6-O-sulfotransferase activity. Predicted to be involved in hexose biosynthetic process. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Is expressed in several structures, including alimentary system; appendicular skeleton; central nervous system; genitourinary system; and sensory organ. Orthologous to human CHST15 (carbohydrate sulfotransferase 15). [provided by Alliance of Genome Resources, Apr 2022]
