32435777-2	2020	Herein, we reported a site-specifically labelled small-sized fluorescent pair 7-HC/FlAsH ((7-hydroxycoumarin-4-yl)-ethylglycine/fluorescein arsenical hairpin) for fluorescence lifetime based FRET (fluorescence resonance energy transfer) to reveal conformational differences of Galphai1 (inhibitory G proteins) and Galphas (stimulatory G proteins) upon beta2AR (beta2-adrenergic receptor) coupling.	Fluorescein	128-139	adenosine A2a receptor	Homo sapiens	352-359
