Application note: Real-time detection of Gs and Gi Signalling in living cells
G-protein coupled receptors (GPCRs) are predominant drug targets. Therefore, monitoring GPCR activity upon compound addition in a cellular context is required. To this end, Montana Molecular developed biosensors that detect G-protein-driven cAMP generation. The sensor consists of a specific cAMP binding domain and a fluorescent label. It changes its fluorescence intensity if the second messenger cAMP is bound.
