Developments in subcellular fractionation strategies have provided the means to profile and
analyze the protein composition of organelles and cellular structures by proteomics. Here …

A challenging task in the study of the secretory pathway is the identification and localization
of new proteins to increase our understanding of the functions of different organelles …

A prominent feature of plant cells is the rapid, incessant movement of the organelles
traditionally defined as cytoplasmic streaming and attributed to actomyosin motility. We …

A full mechanistic understanding of how secretory cargo proteins are exported from the
endoplasmic reticulum for passage through the early secretory pathway is essential for us to …

Vacuoles perform a multitude of functions in plant cells, including the storage of amino acids
and sugars. Tonoplast-localized transporters catalyze the import and release of these …

In protein trafficking, transport vesicles bud from donor compartments and carry cargo
proteins to target compartments with which they fuse. Thus, vesicle formation is an essential …

All eukaryotes possess a secretory pathway, and the major molecular players involved in
secretion are well conserved. However, the morphological manifestation of this pathway at …

In yeast and mammals, amino acid motifs in the cytosolic tails of transmembrane domains
play a role in protein trafficking by facilitating export from the endoplasmic reticulum (ER) …

The perceived role of the ER in the biogenesis of plant peroxisomes has evolved
significantly from the original “ER vesiculation” model, which portrayed co-translational …
