Predicted to enable N-acetylglucosamine 6-O-sulfotransferase activity. Predicted to be involved in N-acetylglucosamine metabolic process; positive regulation of leukocyte tethering or rolling; and protein sulfation. Predicted to act upstream of or within leukocyte tethering or rolling. Predicted to be located in Golgi membrane. Predicted to be active in trans-Golgi network. Orthologous to human CHST4 (carbohydrate sulfotransferase 4). [provided by Alliance of Genome Resources, Apr 2022]
