Predicted to enable N-acetylgalactosamine 4-O-sulfotransferase activity; N-acetylgalactosamine 4-sulfate 6-O-sulfotransferase activity; and chondroitin 4-sulfotransferase activity. Predicted to be involved in proteoglycan biosynthetic process. Predicted to act upstream of or within several processes, including chondroitin sulfate biosynthetic process; post-anal tail morphogenesis; and skeletal system development. Predicted to be located in Golgi membrane. Predicted to be integral component of membrane. Orthologous to human CHST11 (carbohydrate sulfotransferase 11).
