Most proteins that are synthesized on membrane-bound ribosomes are
transported through the Golgi and reach the
trans-Golgi network to be sorted for delivery to
various cellular destinations, including the vacuole. Sorting involves a
recognition of proteins by receptors and the assembly of cytosol-oriented
coat structures that package cargo into vesicles. Vesicle trafficking is
regulated by specific membrane-bound and soluble proteins. Several
components of the secretory machinery have recently been identified in
plants and are described in this review. Ongoing and future research will
characterize features of the secretory pathway specific to plants which,
because of the multiplicity of vacuole types, provide a more complex
paradigm than the better described mammalian and yeast
systems.Keywords: Clathrin coated vesicles, protein
trafficking, receptors, secretory pathway, SNAREs, vesicles
