COPII-mediated traffic in plants
Trends in Plant Science, 2010The secretory pathway encloses functionally interlinked organelles for the synthesis and deposition of most of the building blocks of eukaryotic cells, such as lipids, proteins and sugars. The coat protein complex II (COPII) is a specialized protein complex for the transport between secretory organelles, specifically from the endoplasmic reticulum (ER)

Role of Rab1b in COPII dynamics and function
European Journal of Cell Biology, 2011 In eukaryotic cells, proteins destined for secretion are translocated into the endoplasmic reticulum (ER) and packaged into so-called COPII-coated vesicles. In the ER exit sites (ERES), COPII has the capacity of deforming the lipid bilayer, where it modulates the selective sorting and concentration of cargo proteins.

Mechanisms of COPII vesicle formation and protein sorting [PDF]
FEBS Letters, 2007 The evolutionarily conserved coat protein complex II (COPII) generates transport vesicles that mediate protein transport from the endoplasmic reticulum (ER).

A unique COPII population in plant autophagy
Autophagy, 2021Increasing evidence supports the bona fide function of the coat protein complex II (COPII) machinery in regulating autophagosomes biogenesis during macroautophagy/autophagy induced by nutrient starvation. However, the participation of the COPII machinery in the plant autophagy pathway remains elusive. We recently identified a unique population of COPII

Multifaceted roles of COPII subunits in autophagy
Biochimica Et Biophysica Acta - Molecular Cell Research, 2020 COPII vesicles mediate anterograde ER-Golgi traffic of newly synthesized proteins in nutrient rich conditions. An accumulating body of results indicates that the secretory COPII vesicles can be shifted to the roles in autophagosome formation and selective ER-phagy (autophagy of ER), depending on their specific subunits, in response to environmental ...

COPII and the regulation of protein sorting in mammals
Nature Cell Biology, 2011Secretory proteins are transported to the Golgi complex in vesicles that bud from the endoplasmic reticulum. The cytoplasmic coat protein complex II (COPII) is responsible for cargo sorting and vesicle morphogenesis. COPII was first described in Saccharomyces cerevisiae, but its basic function is conserved throughout all eukaryotes.

Molecular mechanisms of COPII vesicle formation
Seminars in Cell & Developmental Biology, 2007The first step in protein secretion from eukaryotic cells is mediated by COPII vesicles, known for the cytoplasmic coat proteins that are the minimal machinery required to generate these small transport carriers. The five COPII coat components coordinate to create a vesicle by locally generating membrane curvature and populating the incipient bud with ...

COPII-mediated vesicle formation at a glance
Journal of Cell Science, 2011Eukaryotic cells contain a number of different membrane compartments that have specialized roles. Each compartment depends on a specific mixture of proteins for its identity and function. For many compartments, proteins arrive by way of small membrane vesicles that travel through the cell from ...

1999
Abstract Genes encoding COPII proteins were first identified inS. cerevisiae through a genetic screen for secretion defective cells and later found to be required for transport vesicle budding from the ER. Subsequent biochemical approaches allowed for the isolation of three protein fractions, Sec23p/Sec24p complex, Sec13p/Sec31p, and ...

MODIFICATION TO COPII FOR 12XX
1962Abstract : Lockheed Missiles and Space Corporation (LMSC) has the integration responsibility for the 12XX flight series. When System Development Corporation becomes responsible for the 12XX series, it will be converted to the COPII (Control for Operational Programs) System. Outlines features in the 12XX COP that must be integrated into the COPII System.
