Fig. 6. dSyx16 localization in S2 cells. Cells treated with DMSO (A,C,E,G) or brefeldin A (B,D,F,H) were fixed and co-stained with antibodies against p120 (A,B) and dSyx16 (C,D). Note the small but distinct punctate Golgi pattern in the absence of BFA and the big aggregates with BFA treatment. Arrows point to the ring structure, which can be observed at different focal planes in other cells. Scale bar, 10 µM.
