Predicted to enable [heparan sulfate]-glucosamine 3-sulfotransferase 1 activity. Predicted to be involved in several processes, including heparan sulfate proteoglycan biosynthetic process, enzymatic modification; protein sulfation; and regulation of viral entry into host cell. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Orthologous to human HS3ST5 (heparan sulfate-glucosamine 3-sulfotransferase 5).
