To date, a few studies have demonstrated the potential power of GFP-FRET by labeling different proteins [ 6 23 24 25 26 ] or by fusing two different fluorophores to the same protein [ 27 28 29 30 31 32 ] . Creating efficent donor and acceptor fusion proteins is difficult, however, because FRET only occurs when the two fluorophores are attached to surfaces that are very close to one another.
The approach described here makes it possible to rapidly generate libraries of potential donor and acceptor tribrid fusion proteins that can be screened, in pairwise combinations, for function and FRET signals.
