Tyrosylprotein Sulfotransferase 2/TPST2 Lysates

Tyrosine O-sulfation is a posttranslational modification found in all multicellular organisms. This reaction is mediated by tyrosylprotein sulfotransferase (TPST), a Golgi enzyme that transfers sulfate from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to tyrosine residues contained in polypeptides with acidic motifs to form a tyrosine O-sulfate ester. More than 60 proteins have been identified to be tyrosine sulfated. The function of this modification have been identified in some cases. For ...
