Abstract

At the center of the secretory pathway, the Golgi complex ensures correct processing and sorting of cargos toward their final destination. Cargos are diverse in topology, function and destination. A remarkable feature of the Golgi complex is its ability to sort and process these diverse cargos destined for secretion, the cell surface, the lysosome, or retained within the secretory pathway. Just as these cargos are diverse so also are their sorting requirements and thus, their trafficking route. There is no one-size-fits-all sorting scheme in the Golgi. We propose a coexistence of models to reconcile these diverse needs. We review examples of differential sorting mediated by proteins and lipids. Additionally, we highlight recent technological developments that have potential to uncover new modes of transport.
