Time-resolved FRET strategy to screen GPCR ligand library.

Screening chemical libraries to find specific drugs for G protein-coupled receptors is still of major interest. Indeed, because of their major roles in all physiological functions, G protein-coupled receptors remain major targets for drug development programs. Currently, interest in GPCRs as drug targets has been boosted by the discovery of biased ligands, thus allowing the development of drugs...

BRET and Time-resolved FRET strategy to study GPCR oligomerization: from cell lines toward native tissues

The concept of oligomerization of G protein-coupled receptor (GPCR) opens new perspectives regarding physiological function regulation. The capacity of one GPCR to modify its binding and coupling properties by interacting with a second one can be at the origin of regulations unsuspected two decades ago. Although the concept is interesting, its validation at a physiological level is challenging ...

G Protein-selective GPCR Conformations Measured Using FRET Sensors in a Live Cell Suspension Fluorometer Assay.

Fӧrster resonance energy transfer (FRET)-based studies have become increasingly common in the investigation of GPCR signaling. Our research group developed an intra-molecular FRET sensor to detect the interaction between Gα subunits and GPCRs in live cells following agonist stimulation. Here, we detail the protocol for detecting changes in FRET between the β2-adrenergic receptor and the Gαs C-t...

Structural kinetics of myosin by transient time-resolved FRET.

For many proteins, especially for molecular motors and other enzymes, the functional mechanisms remain unsolved due to a gap between static structural data and kinetics. We have filled this gap by detecting structure and kinetics simultaneously. This structural kinetics experiment is made possible by a new technique, (TR)(2)FRET (transient time-resolved FRET), which resolves protein structural ...

Investigating State Restriction in Fluorescent Protein FRET Using Time-Resolved Fluorescence and Anisotropy

Most fluorescent proteins exhibit multiexponential fluorescence decays, indicating a heterogeneous excited state population. FRET between fluorescent proteins should therefore involve multiple energy transfer pathways. We recently demonstrated the FRET pathways between EGFP and mCherry (mC), upon the dimerization of 3-phosphoinositide dependent protein kinase 1 (PDK1), to be highly restricted. ...
