Data Sheet

Background: The G protein-coupled bile acid receptor GPBAR1 (or GPR131) mediates bile acids-induced rapid elevation of intracellular cAMP levels. It is implicated in the suppression of macrophage functions and regulation of energy homeostasis by bile acids.

Application: Functional assays

Figure 1. Dose-dependent increase of intracellular cAMP upon treatment with ligand, measured with MultiscreenTM TR-FRET cAMP 1.0 No Wash Assay Kit (Multispan MSCM01). Figure 2. Receptor expression on cell surface measured by flow cytometry (FACS) using an anti-FLAG antibody. Thin line: parental cells; thick line: receptor-expressing cells.
