The FRET signal was increased when Rac -G12V was used (Fig 3a).The FRET signal was increased when the cells microinjected with the two proteins were incubated with fibronectin-coated beads. (Fig 4a, 4c). Incubation with anti-beta1 integrin-coated beads also increased the FRET signal (Fig 4b). The FRET signal was decreased when the cells were incubated with anti-CD44-coated beads. The FRET signal was weak when the cells were injected with GFP-V12-Rac-6Q, even when incubated with fibronectin-coated beads (Fig 4d). The effect of the GFP-T35S/Q61L-Rac and GFP-G12V/C189S-Rac constructs on the FRET signal could not be curated since the source of these constructs could not be traced.
