Anti-TPST2 antibodies are used in the immunodetection of the protein tyrosylprotein sulfotransferase 2. In humans, the canonical protein has a reported length of 377 amino acid residues and a mass of 41.9 kDa. Its subcellular localization is in the Golgi. It is widely expressed across many tissue types. A member of the Protein sulfotransferase protein family, TPST2 is known to catalyze the O-sulfation of tyrosine residues within acidic motifs of polypeptides, using 3'-phosphoadenylyl sulfate (PAPS) as cosubstrate. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include protein-tyrosine sulfotransferase 2, transport and golgi organization 13 homolog B, tyrosylprotein phosphotransferase 2, and TANGO13B. TPST2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Western Blot is the most common application for the TPST2 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
