While distinct from the CGN or TGN, we assume that the medial cisternae represent a single functionally continuous compartment, irrespective of the actual number of physically separate cisternal elements in any one Golgi complex. Given that VSV G protein in early Golgi compartments was transported with the highest efficiency (Fries and Rothman, 1981) the transport event assayed was postulated to reflect the formation of vesicles from cis (early) cisternae and the fusion of these vesicles with medial cisternae (which contain the GlcNAc transferase) (Rothman and Orci, 1990) (Figure 4) . ./cache/cord-287815-alv30uk5.txt ./txt/cord-287815-alv30uk5.txt
