Genetically Encoded FRET Biosensors to Illuminate Compartmentalised GPCR Signalling

Genetically Encoded FRET Biosensors to Illuminate Compartmentalised GPCR Signalling
Michelle L. Halls, Meritxell Canals

Genetically encoded Förster resonance energy transfer (FRET) biosensors have been instrumental to our understanding of how intracellular signalling is organised and regulated within cells. In the last decade, the toolbox, dynamic range and applications of these sensors have expanded beyond basic cell biology applications. In particular, FRET biosensors have shed light onto the mechanisms that control the intracellular organisation of G protein-coupled receptor (GPCR) signalling and have allowed the visualisation of signalling events with unprecedented temporal and spatial resolution. Here we review the use of these sensors in the GPCR field and how it has already provided invaluable advances towards our understanding of the complexity of GPCR signalling.
