EXAMPLE FRET-FLIM Conformational changes<br />

GFP at the N-terminus and YFP at the C-terminus<br />

GFP-Akt<br />

GFP-Akt-YFP<br />

YFP-Akt<br />

GFP-Akt-YFP dark<br />

>> short lifetime<br />

>> lifetime increases because of YFP<br />

>> long lifetime<br />

>> = lifetime of GFP-Akt<br />

YFP emission quenced (Tyr 67 mutated to Leu)<br />
