Tyrosylprotein Sulfotransferase 1/TPST1: Products

Tyrosine O-sulfation is a posttranslational modification of proteins in all multicellular organisms. This reaction is mediated by a Golgi enzyme activity called Tyrosylprotein Sulfotransferase (TPST) that transfers sulfate from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to tyrosine residues within acidic motifs of polypeptides to form tyrosine O-sulfate ester. More than 60 proteins have been identified to be tyrosine sulfated, for some of which the functions have been identified. For example, sulfation of tyrosine residues in the leukocyte adhesion molecule P-selectin glycoprotein ligand 1 (PSGL-1) is required for binding to P-selectin on activated endothelium.
