Enables 3'-phosphoadenosine 5'-phosphosulfate binding activity; aryl sulfotransferase activity; and identical protein binding activity. Involved in several processes, including 4-nitrophenol metabolic process; estrogen metabolic process; and response to activity. Located in cytosol. Human ortholog(s) of this gene implicated in several diseases, including breast cancer; gastrointestinal system cancer (multiple); lung cancer (multiple); reproductive organ cancer (multiple); and urinary bladder cancer. Orthologous to several human genes including SULT1A1 (sulfotransferase family 1A member 1). [provided by Alliance of Genome Resources, Apr 2022]
