  • In an active model for sorting ('sorting by entry'), membrane binding of secretory proteins is assumed to depend on a 'sorting receptor' within the TGN (e.g., a transmembrane protein), and entry into forming granules is restricted to receptor-mediated trafficking. (medscape.com)

  • These condensing vacuoles (CVs), the initial stage of ZGs, then pinch off as immature granules, which mature into ZGs by the selective removal of nonsecretory granule proteins (via a clathrin-mediated process called 'constitutive-like secretion') and further condensation of the aggregated proteins occurs, as well as a reduction in granule size.
