硫酸乙酰肝素蛋白聚糖存在于细胞表面和细胞外基质中,在那里它们与过多的配体相互作用。在过去的十年中,新的见解已经出现了关于这些相互作用的机制和生物学意义。在这里,我们讨论了不断变化的观点上的特异性蛋白质硫酸乙酰肝素结合和活性的HSPGs受体和辅助受体。硫酸乙酰肝素蛋白聚糖虽然数量很少,但在细胞、组织和生物体水平上具有深远的影响。
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 coreceptors. Although fewin number, heparan sulfate proteoglycans have profound effects at the cellular, tissue, and organismal level.
