Heparan sulfate (HS) is a linear polysaccharide found in all animal tissues. It occurs as a proteoglycan (HSPG, i.e. Heparan Sulfate ProteoGlycan) in which two or three HS chains are attached in close proximity to cell surface or extracellular matrix proteins. It is in this form that HS binds to a variety of protein ligands, … Visualizza altro The major cell membrane HSPGs are the transmembrane syndecans and the glycosylphosphatidylinositol (GPI) anchored glypicans. Other minor forms of membrane HSPG include betaglycan and the V-3 … Visualizza altro Many different cell types produce HS chains with many different primary structures. Therefore, there is a great deal of variability in … Visualizza altro Heparan sulfate analogues are thought to display identical properties as heparan sulfate with exception of being stable in a proteolytic environment like a wound. Because heparan sulfate is broken down in chronic wounds by heparanase, the analogues … Visualizza altro Heparan sulfate is a member of the glycosaminoglycan family of carbohydrates and is very closely related in structure to heparin. Heparin, commonly known as an anticoagulant, is a highly sulfated form of HS which, in contrast to HS, is mainly found in mast … Visualizza altro Heparan sulfate binds with a large number of extracellular proteins. These are often collectively called the “heparin interactome” or "heparin-binding proteins", because they are isolated by affinity chromatography on the related polysaccharide … Visualizza altro WebAbstract.
