Heparan sulfate proteoglycans.
Heparan sulfate proteoglycans are found at the cell surface and in the extracellular matrix, where they interact with a plethora of ligands. Over the last decade, new insights have emerged regarding the mechanism and biological significance of these interactions. Here, we discuss changing views on the specificity of protein-heparan sulfate binding and the activity of HSPGs as receptors and core...
متن کاملHeparan sulfate proteoglycans
Studies of the involvement of ECM molecules in cell attachment, growth, and differentiation have revealed a central role of heparan sulfate (HS) proteoglycans (HSPGs) in early embryogenesis, morphogenesis, angiogenesis, and epithelial-mesenchymal interactions (1–3). HS chains bind a multitude of proteins and ensure that a wide variety of bioactive molecules (e.g., heparin-binding growth factors...
متن کاملHeparan Sulfate Proteoglycans in Infection
To cause infections, microbial pathogens elaborate a multitude of factors that interact with host components. Using these host–pathogen interactions to their advantage, pathogens attach, invade, disseminate, and evade host defense mechanisms to promote their survival in the hostile host environment. Many viruses, bacteria, and parasites express adhesins that bind to cell surface heparan sulfate...
متن کاملIntegral membrane heparan sulfate proteoglycans.
Heparan sulfate is a regulatory polysaccharide. It modulates specific growth factor-receptor interactions, accelerates the formation of specific proteinase-proteinase inhibitor complexes, and mediates interactions of the cell surface with several enzymes and structural proteins. It abounds on the surfaces of embryonic cells, respecting or outlining morphogenetic rather than histological boundar...
متن کاملAlterations of Heparan Sulfate Proteoglycans in Cancer
Heparan sulfate proteoglycans (HSPGs) are glycoproteins, with the common characteristic of containing covalently attached heparan sulfate glycosaminoglycan chains (GAGs). These molecules are highly modified in cancer, contributing to tumorigenesis. In fact, the expression of HSPGs is markedly altered during malignant transformation and tumor progression, affecting both the PG core proteins and ...
