The importance of tyrosine O-sulfation in protein-protein interactions is illustrated by the sulfation of tyrosine residues in the leukocyte adhesion molecule P-selectin glycoprotein ligand-1; sulfation is required for its binding to P-selectin on activated endothelium. This enzyme represents a new class of Golgi sulfotransferases that catalyze tyrosine O-sulfation of many protein substrates involved in diverse physiologic functions including inflammation, hemostasis, body weight and reproductive physiology.
