Abstract | Heparan sulfate (HS) proteoglycans, at the cell surface and extracellular matrix, facilitate ligand-receptor interactions crucial to many physiological processes. The distinct sulfation patterns of HS sugar chains presented by their protein core are key to HS proteoglycan activity. Tight regulation of several Golgi complex enzyme families is crucial to produce complex tissue-specific HS sequences. Several in vivo models deficient in HS biosynthesis enzymes demonstrate that developmental abnormalities result from modified HS structure. This review will discuss the plasticity of sulfation requirements on HS for activating protein ligands, which might reflect a flexible HS biosynthetic mechanism. In addition, the latest discovery of HS acting enzymes, the Sulfs, responsible for extracellular tweaking of HS sulfation levels subsequent to biosynthesis will be considered. |
