Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection. [PDF]

New Phytol
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

Trafficking of the human Na⁺/H⁺ antiporter NHA2 to the plasma membrane requires cornichon COPII cargo receptors. [PDF]

Protein Sci
Abstract A key prerequisite of transporter proteins' function is their trafficking to the target cellular membranes where they fulfill distinct physiological roles. Cornichon proteins (CNIH/Erv14) represent a highly conserved family of coat protein complex II (COPII)‐coated vesicle cargo receptors that facilitate the exit of numerous transporters from ...

COP-coated vesicles are involved in the mitotic fragmentation of Golgi stacks in a cell-free system. [PDF]

The Journal of cell biology, 1994
Rat liver Golgi stacks fragmented when incubated with mitotic but not interphase cytosol in a process dependent on time, temperature, energy (added in the form of ATP) and cdc2 kinase. The cross-sectional length of Golgi stacks fell in the presence of mitotic cytosol by approximately 50% over 30 min without a corresponding decrease in the number of ...

Proteomic and Lipidomic Profiling of Immune Cell-Derived Subpopulations of Extracellular Vesicles. [PDF]

Proteomics
ABSTRACT Extracellular vesicles (EVs) are heterogeneous and play important roles in intercellular communication, contributing to physiological and pathological processes. Since few markers currently exist to differentiate subtypes of EVs, this study aimed to determine proteomic and lipidomic differences among four EV subpopulations. Large and small EVs

An ancestral secretory apparatus in the protozoan parasite Giardia intestinalis [PDF]

, 2003
The protozoan parasite Giardia intestinalis belongs to one of the earliest diverged eukaryotic lineages. This is also reflected in a simple intracellular organization, as Giardia lacks common subcellular compartments such as mitochondria, peroxisomes ...

The structure of the COPI coat determined within the cell

eLife, 2017
COPI-coated vesicles mediate trafficking within the Golgi apparatus and from the Golgi to the endoplasmic reticulum. The structures of membrane protein coats, including COPI, have been extensively studied with in vitro reconstitution systems using ...

Dissection of GTPase activating proteins reveals functional asymmetry in the COPI coat of budding yeast. [PDF]

, 2019
The Arf GTPase controls formation of the COPI vesicle coat. Recent structural models of COPI revealed the positioning of two Arf1 molecules in contrasting molecular environments.

Silkworm coatomers and their role in tube expansion of posterior silkgland.

PLoS ONE, 2010
BackgroundCoat protein complex I (COPI) vesicles, coated by seven coatomer subunits, are mainly responsible for Golgi-to-ER transport. Silkworm posterior silkgland (PSG), a highly differentiated secretory tissue, secretes fibroin for silk production, but

9Å structure of the COPI coat reveals that the Arf1 GTPase occupies two contrasting molecular environments

eLife, 2017
COPI coated vesicles mediate trafficking within the Golgi apparatus and between the Golgi and the endoplasmic reticulum. Assembly of a COPI coated vesicle is initiated by the small GTPase Arf1 that recruits the coatomer complex to the membrane ...
