Predicted to enable [heparan sulfate]-glucosamine 3-sulfotransferase 1 activity. Involved in circadian rhythm. Predicted to be located in Golgi membrane. Predicted to be integral component of membrane. Human ortholog(s) of this gene implicated in colon cancer; lung cancer; and pancreatic cancer. Orthologous to human HS3ST2 (heparan sulfate-glucosamine 3-sulfotransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
