[Abstract]  Cell-based functional assays are an important part of compound screening and drug lead optimization, and they can also play a crucial role in the determination of the residues involved in ligand binding and signaling for a particular G-protein-coupled receptor. Conventional methods used for Gαq/15-coupled receptors rely on the use of fluorescent probes for Ca++ sensing (such as Fura-2 and Fluo-4) or on the incorporation of [3H]-inositol into inositol 1,4,5- triphosphate (IP3). However, these methods are not suitable for screening large libraries of compounds or for screening several mutants of the same receptor. In contrast, the IP-One assay by Cisbio is a TR-FRET assay suitable for large compound library screening when using stable cell lines that express ...

[背景 ] 七跨膜受体(7TMR),也被称为G蛋白偶联受体,是超家族参与信号转导的最重要的跨膜蛋白。它们是临床批准药物的30%至50%的目标(Overington 等,2006)。Gαq / 15 偶联的7TMR激活磷脂酶Cβ(PLCβ),并产生D-肌醇1,4,5-三磷酸(IP3)和二酰基甘油(DAG)。IP3触发细胞内Ca ++ ...
