g蛋白偶联受体(gpcr)是一类重要的药物靶点。然而,受体测定是基于测量配体位移或下游功能反应,而不是直接观察配体结合。变构调节,探针依赖性和功能选择性的问题,在选择合适的分析格式的挑战。因此,一种直接测量gpcr -配体相互作用的方法,独立于结合位点、探针和信号通路,将是一种有用的初级和正交筛选方法。我们已经开发了一种GPCR生物传感器检测方案,提供了直接测量GPCR配体相互作用的高通量无标签筛选的机会。基于生物传感器的直接筛选方法可以在无标记和无细胞的环境中识别出正构和变构配体与溶解的天然gpcr的相互作用,从而克服了间接和位移测定方法的局限性。我们通过发现趋化因子受体CCR5的新型配体来举例说明这种方法,这是配体有效的片段。
G-protein coupled receptors (GPCRs) are a class of drug targets of primary importance. However, receptor assays are based on measurement of either ligand displacement or downstream functional responses, rather than direct observation of ligand binding. Issues of allosteric modulation, probe dependence, and functional selectivity create challenges in selecting suitable assays formats. Therefore, a method that directly measures GPCR–ligand interactions, independent of binding site, probe, and signaling pathway would be a useful primary and orthogonal screening method. We have developed a GPCR biosensor assay protocol that offers the opportunity for high-throughput label-free screening that directly measures GPCR–ligand interactions. The biosensor-based direct screening method identifies the interaction of both orthosteric and allosteric ligands with solubilized, native GPCRs, in a label-free and cell-free environment, thus overcoming the limitations of indirect and displacement assay methods. We exemplify the method by the discovery of novel ligands for the chemokine receptor, CCR5, that are ligand efficient fragments.
