Predicted to enable heparan sulfate 2-O-sulfotransferase activity. Predicted to be involved in heparan sulfate proteoglycan biosynthetic process, enzymatic modification and heparan sulfate proteoglycan biosynthetic process, polysaccharide chain biosynthetic process. Predicted to act upstream of or within gene expression; heparin metabolic process; and ureteric bud formation. Predicted to be located in Golgi membrane. Predicted to be integral component of membrane. Orthologous to human HS2ST1 (heparan sulfate 2-O-sulfotransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
