Enables sulfotransferase activity. Involved in positive regulation of leukocyte tethering or rolling. Predicted to be located in Golgi apparatus; cytosol; and nucleoplasm. Predicted to be active in trans-Golgi network. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human CHST2 (carbohydrate sulfotransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
