WebHeparan sulfate (HS) is a component of the extracellular matrix. It is a glycosaminoglycan that is covalently attached to core proteins to form proteoglycans. Its structure is amazingly diverse since during synthesis it undergoes extensive sulfation and epimerization. Heparin is distinct from HS in that it is produced primarily by mast cells ... WebHeparan sulfate biosynthesis: regulation and variability Nearly all vertebrate cells have been shown to express heparan sulfate proteoglycans (HSPGs) at the cell surface. The HSPGs bind to many secreted signaling proteins, including numerous growth factors, cytokines, and morphogens, to affect their tissue distribution and signaling.
