Wild-type Arf1-GFP (Arf1(WT)-GFP) (gray) colocalizes primarily at the Golgi (Giantin) (red) with Helix Pomatia Lectin (HPL) (green) in unstimulated HeLa cells. HPL binds various glycans but the Tn ant...

Constitutively active mutant Arf1-GFP (Arf1(Q71L)-GFP) (gray) colocalizes primarily at the Golgi (Giantin) (red) with Helix Pomatia Lectin (HPL) (green) in unstimulated HeLa cells. HPL binds various g...

Co-expression of wild-type Arf1-GFP (Arf1(WT)-GFP) (gray) and inactive Src (SrcK-DsRed) (red) in Src-deficient SYF fibroblasts does not induce trafficking of Helix Pomatia Lectin (HPL) (green) from t...

COP-I beta1 (green) staining at the Golgi (GM130, a cis-Golgi marker) (red) in unstimulated HeLa cells. Helix Pomatia Lectin (HPL) (gray) staining is also shown. HPL binds various glycans but the Tn a...

Constituvely active mutant Arf1-GFP (Arf1(Q71L)-GFP) (gray) blocks redistribution of Helix Pomatia Lectin (HPL) (green) from Golgi to ER in Src-deficient SYF fibroblasts cotransfected with active Src...

COP-I gamma1 (green) staining at the Golgi (GM130, a cis-Golgi marker) (red) in unstimulated HeLa cells. Helix Pomatia Lectin (HPL) (gray) staining is also shown. HPL binds various glycans but the Tn ...

After EGF stimulation for 4 h, Helix Pomatia Lectin (HPL) (green) in HeLa cells expressing wild-type Arf1-GFP (Arf1(WT)-GFP) (gray) is redistributed from Golgi (Giantin) (red) to ER. HPL binds various...

GalNac-T1 (green) is in dispersed punctate structures that stain positive for COP-I gamma1 (red) after EGF treatment of HeLa cells for 4h. These data suggest that GalNAc-Ts are being redistributed fro...

COP-I beta1 (green) staining at the Golgi (GM130, a cis-Golgi marker) (red), is redistributed out of the Golgi after EGF treatment of HeLa cells for 4 h. The increase in number and intensity of puncta...

GalNac-T1 staining (green) colocalizes with COP-I beta1 (red) staining at the Golgi (HPL) (gray) in unstimulated HeLa cells. Helix Pomatia Lectin (HPL) binds various glycans but the Tn antigen in part...
