The trans-Golgi network (TGN) is a major sorting, packing and delivering station of newly synthesised proteins and lipids to their final destination. These cargo molecules follow the secretory pathway, which is a vital part of cellular trafficking machinery in all eukaryotic cells. This secretory pathway is well conserved in all eukaryotes from low-level eukaryotes, such as yeast, to higher level eukaryotes like mammals. The molecular mechanisms of protein sorting by adaptor proteins, membrane elongation and transport to the final destinations by motor proteins and the cytoskeleton, and membrane pinching-off by scission proteins must be choreographically managed for efficient cargo delivery, and the understanding of these detailed processes is not yet completed. Functionally, defects in these mechanisms are associated with the pathology of prominent diseases such as acute myeloid leukaemia, Charcot-Marie-Tooth disease, I-cell disease and Wiskott-Aldrich syndrome. The present review points out the recent advances in our knowledge of the molecular mechanisms involved in the transportation of the cargo from the TGN towards the endosome.
