title: Secretory granule and synaptic vesicle formation.
abstract: Sorting of secreted proteins into dense-core secretory granules may involve selective aggregation of regulated secretory proteins, rather than a conventional sortase. Synaptic vesicles, which mediate paracrine communication between adjacent cells, appear to arise by a modification of the early endosome pathway. Targeting to the cell surface involves the actin-based cytoskeleton and small GTP-binding proteins.
