mint The data indicated that oxidative stress may liberate JTV1 from the ARS complex to enable its nuclear translocation. JTV1 relocalization to the nucleus was also observed with MCF7 and HCT-116 cells (Figure 3D; Supplementary Figure S6) The results showed that although GFP-JTV1 was always predominantly cytoplasmic; cells with increased GFP-JTV1 expression exhibited an increase in nuclear fluorescence that partly co-localized with nuclear FBP (Figure 3Ae versus f and 3Ac). f3a aimp2-pml 3 JTV1 8 immunostaining immunostaining predetermined predetermined participant predetermined unspecified role unspecified role neutral component neutral component physiological level physiological level endogenous level endogenous endogenous endogenous level fixed cell fixed cell PML 9 immunostaining immunostaining predetermined predetermined participant predetermined unspecified role unspecified role neutral component neutral component physiological level physiological level endogenous level endogenous endogenous endogenous level fixed cell fixed cell colocalization colocalization homomint mint f3h fubp1-ja 3 JTV1-Alt 12 tag fluorescence tag visualisation by fluorescence tag fluorescence predetermined predetermined participant predetermined unspecified role unspecified role neutral component neutral component over-expressed over expressed level over-expressed fixed cell fixed cell gfp tag gfp tag green fluorescent protein tag GFP green fluorescent protein GFP green fluorescent protein gfp tag undetermined undetermined sequence position undetermined undetermined undetermined sequence position undetermined FBP 13 tag fluorescence tag visualisation by fluorescence tag fluorescence predetermined predetermined participant predetermined unspecified role unspecified role neutral component neutral component over-expressed over expressed level over-expressed fixed cell fixed cell fusion protein fusion protein fusion protein undetermined undetermined sequence position undetermined undetermined undetermined sequence position undetermined colocalization colocalization homomint mint In contrast, JA, lacking the majority of the amino acids required for incorporation into the ARS complex (Kim et al, 2002), was predominantly nuclear regardless of expression levels (Figure 3Ba; Supplementary Figure S3). Live cell con- focal imaging showed that GFP-JA co-localized with FBP at multiple intranuclear foci (Figure 3Ba and b (zoomed view of panel a)). Dissolution of these foci following a 2-h actinomy- cin D treatment suggested that JTV1/FBP complexes are maintained by ongoing transcription (Figure 3Bc).
