The trans-Golgi network is a major sorting platform of the secretory pathway from which proteins and lipids, both newly synthesized and retrieved from endocytic compartments, are targeted to different destinations. These sorting processes occur during the formation of pleomorphic tubular-vesicular carriers. The past years have provided insights into basic mechanisms coordinating the spatial and temporal organization of machineries necessary for the segregation of membrane components into distinct microdomains, for the bending, elongation, and fission of corresponding membranes, thus revealing a complex interplay of protein-protein and protein-lipid interactions.
