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...

High resolution micrograph following trifluoperizine (TFP) treatment, which apparently does not inhibit endocytosis but does inhibit movement of vesicles away from the parasomal sacs, coated and preen...

Nuclear envelope and spindle dynamics when the nucleus moves into the neck of kar9delta mutant cells arrested in S phase. Movie plays at 100x real time and is movie S5 in Proc Natl Acad Sci. 2009. 106...

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...

High resolution image of a cell treated with trifluoperizine (TFP), all stages of endocytosis and movement to the early endosomes and out of the early endosomes can be found. These steps begin at the ...

An image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cisternae are earl...

In a cell treated with trifluoperizine (TFP), all stages of endocytosis and movement to the early endosomes and out of the early endosomes can be found. These steps begin at the parasomal sac and endi...

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 ...
