As such, both cargoes are too large to fit into the sizes typical of COPII-coated vesicles (60–100 nm diameter). Figure 4: Basis for cage flexibility and incorporation of large cargoes.

“Our images showed us how the proteins that make up the coat are arranged and it was surprising to discover how different COPI is from, for example, clathrin or COPII coated vesicles,” stated ...

Some steps of membrane transport require the formation of vesicles coated with COPI, COPII or clathrin. The coats probably generate the forces necessary to bend a relatively flat membrane into a ...

"Our images showed us how the proteins that make up the coat are arranged and it was surprising to discover how different COPI is from, for example, clathrin or COPII coated vesicles," adds ...

that helps in concentrating the cargo at the ER and budding off the small vesicles that are consequently called COPII-coated vesicles (transport vesicles; coat protein complex II). But this knowledge ...

After folding and proper modification, cargo proteins exited the ER through COPII coated vesicles. Researchers found that in ATL-deleted cells, COPII formation was drastically reduced in the cell ...

One third of the proteins essential for life processes are produced in the endoplasmic reticulum (ER) of the cell and distributed via membrane vesicles. Sorting of proteins at ER exit sites and ...

After it fills with cargo, the pit pinches off to form a clathrin-coated, membrane-bound vesicle inside the cell, which then proceeds to its proper destination. In cultured cells, hundreds of these ...

In this case, IgA seems to unintentionally intensify inflammatory processes. The IgA-coated vesicle binds selectively to receptor CD89, which is present in certain immune cells in the gut.

"Our images showed us how the proteins that make up the coat are arranged and it was surprising to discover how different COPI is from, for example, clathrin or COPII coated vesicles," adds Svetlana ...
