Coordination of COPII vesicle trafficking by Sec23
Trends in Cell Biology, 2008Coat protein complex II (COPII) is a multi-subunit protein complex responsible for the formation of membrane vesicles at the endoplasmic reticulum. The assembly of this complex on the endoplasmic reticulum membrane needs to be tightly regulated to ensure efficient and specific incorporation of cargo proteins into nascent vesicles.

Abstract : The upper portion of core from approximately 75400B to 77777B is now used by the COPII (Control for Operational Programs) System for the directory and other tables. Some functions in the system either require all of core from 10000B to 77777B or are very close to requiring the area now used for the directory.

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.

The COPII cage sharpens its image
Nature Structural & Molecular Biology, 2013Self-assembly of the COPII coat proteins Sec13 and Sec31 creates a spherical cage that drives vesicle formation from the endoplasmic reticulum. A multipronged approach now provides a convincing pseudoatomic model of the assembled cage that sharpens our understanding of the architecture, contact sites and flexibility of this remarkable structure.

p38 MAPK regulates COPII recruitment
Biochemical and Biophysical Research Communications, 2007Here, we investigate regulation of coat protein complex II (COPII) recruitment onto ER export sites in permeabilized cells. In cytosols from nocodazole treated HeLa cells we find COPII loading is inhibited. The stress kinase p38 MAPK is activated in these cytosols and COPII loading can be rescued by depletion of p38 MAPK alpha or by the p38 MAPK ...

Illuminating COPII coat dynamics
Nature Structural & Molecular Biology, 2005A FRET-based approach to monitor the assembly of membrane-associated COPII coat proteins provides new insights into how the COPII–cargo complex is maintained on the membrane during continuous rounds of Sar1p-GTP hydrolysis.

In Vitro Reconstitution of Plant COPII Vesicles
In vitro reconstitution studies enable the controllable and stepwise investigation of complicated biochemical processes. In yeast and mammals, in vitro reconstitution of COPII vesicles marked a pivotal point in characterizing the endoplasmic reticulum-to-Golgi anterograde trafficking route and revealed how vesicles mediate the selective and reliable ...Baiying, Li, Liwen, Jiang
