TL;DRAbstract

Syndecan-1 is a cell surface proteoglycan which participates in cell adhesion, differentiation, motility, morphogenesis and intracellular signaling. The two glycosaminoglycans heparan sulfate and chondroitin sulfate are covalently attached to the ectodomain of syndecan-1 via a tetra saccharide linkage sequence. However, the ectodomain can be modified having only one or neither of the glycosaminglycans attached. The glycosaminoglycans are capable of binding ligands such as fibroblast growth factors (FGFs) and support activation of receptors. The ectodomain is proteolytically cleaved from the cell surface by metalloproteinases in a process known as shedding. Shedding turns the ectodomain into a soluble effector which can stimulate other cells in the surroundings by delivering growth factors and also translocate into cells through endocytosis. In this study the aim was to find out if a modified ectodomain, which only contains chondroitin sulfate, could support intracellular signaling in t
