Study of the plant COPII vesicle coat subunits by functional complementation of yeast Saccharomyces cerevisiae mutants.

PLoS ONE, 2014
The formation and budding of endoplasmic reticulum ER-derived vesicles depends on the COPII coat protein complex that was first identified in yeast Saccharomyces cerevisiae. The ER-associated Sec12 and the Sar1 GTPase initiate the COPII coat formation by

Protein trafficking through the endosomal system prepares intracellular parasites for a home invasion [PDF]

, 2013
Toxoplasma (toxoplasmosis) and Plasmodium (malaria) use unique secretory organelles for migration, cell invasion, manipulation of host cell functions, and cell egress. In particular, the apical secretory micronemes and rhoptries of apicomplexan parasites

The C-terminus of the cargo receptor Erv14 affects COPII vesicle formation and cargo delivery

bioRxiv, 2022
The endoplasmic reticulum (ER) is the start site of the secretory pathway, where newly synthesized secreted and membrane proteins are packaged into COPII vesicles through direct interaction with the COPII coat or aided by specific cargo receptors. Little

Construction of pathogenic Sec16a mutation mouse model using CRISPR/Cas9

Animal Models and Experimental Medicine, EarlyView.
Yaqiang Hu et al. engineered a pathogenic Sec16a mutant mouse model using CRISPR/Cas9 technology. They observed that the Sec16a mutant mice displayed diminished learning and memory capabilities, along with a limb‐clasping phenotype upon tail suspension.

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 ...

Plasmodesmata‐located proteins: The molecular hubs in noncell‐autonomous immunity

New Plant Protection, EarlyView.
Plasmodesmata serve as critical battlefields for plant immunity, regulated by diverse proteins. This article provides a comprehensive review of the regulatory mechanisms, challenges, and future directions concerning proteins located within plasmodesmata and their roles in plant defense responses.

The ufmylation cascade controls COPII recruitment, anterograde transport, and sorting of nascent GPCRs at ER

Science Advances
Ufmylation is implicated in multiple cellular processes, but little is known about its functions and regulation in protein trafficking. Here, we demonstrate that the genetic depletion of core components of the ufmylation cascade, including ubiquitin-fold

Ultrastructure of COPII vesicle formation characterised by correlative light and electron microscopy

bioRxiv, 2022
Traffic of proteins out of the endoplasmic reticulum (ER) is driven by the COPII coat, a layered protein scaffold that mediates the capture of cargo proteins and the remodelling of the ER membrane into spherical vesicular carriers.

Proteomic and Lipidomic Profiling of Immune Cell‐Derived Subpopulations of Extracellular Vesicles

PROTEOMICS, EarlyView.
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
