Catalyzes the O-sulfation of tyrosine residues within acidic motifs of polypeptides, using 3'-phosphoadenylyl sulfate (PAPS) as cosubstrate. 3'-phosphoadenylyl sulfate + L-tyrosyl-[protein] = adenosine 3',5'-bisphosphate + H(+) + O-sulfo-L-tyrosine-[protein] Homodimer. Can also form heterodimers with TPST2. N-glycosylated. Belongs to the protein sulfotransferase family.
