Predicted to enable heparan sulfate 6-O-sulfotransferase activity. Predicted to be involved in heparan sulfate proteoglycan biosynthetic process, enzymatic modification. Predicted to be located in membrane. Human ortholog(s) of this gene implicated in Paganini-Miozzo syndrome. Orthologous to human HS6ST2 (heparan sulfate 6-O-sulfotransferase 2).
