Fig. 6. Determinants affecting R-Ras targeting. HeLa cells were transiently
transfected with pEGFP-R-Ras38V-NT (A,B), pEGFPHVR (C,D), pEGFP-R-Ras38V-dHVR
(E,F), pEGFP-R-Ras38V-2PA (G,H), pEGFP-R-Ras38V-CA (I,J), pEGFP-R-Ras38V-SP
(K,L) and pEGFP-R-Ras38V-dC (M,N), fixed and stained with anti-vinculin.
Observe the absence of EGFP-HVR from vinculin-containing adhesions. Note the
accumulation of R-Ras38V-dHVR, R-Ras38VCA in Golgi and R-Ras38V-SP in ER.
EGFP-R-Ras38V-dC that lacks signals for lipid modifications is found in the
nucleus.
