The Sec13/31 Complex is a crucial component of the COPII vesicle coat, which is essential for the transport of proteins from the endoplasmic reticulum to the Golgi apparatus. It functions by stabilizing the outer layer of the vesicle and facilitating the budding process necessary for vesicle formation and cargo selection.

Sec13/31 Complex

COPII vesicle coat is a protein complex responsible for the transport of proteins from the endoplasmic reticulum to the Golgi apparatus in eukaryotic cells. It plays a crucial role in the secretory pathway by selecting cargo and forming vesicles that bud off from the ER membrane.

transport of proteins

The endoplasmic reticulum (ER) is a vital cellular organelle responsible for the synthesis, folding, modification, and transport of proteins and lipids. It exists in two forms: rough ER, studded with ribosomes for protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification processes.

endoplasmic reticulum

The Golgi apparatus is a critical cellular organelle responsible for modifying, sorting, and packaging proteins and lipids for secretion or delivery to other organelles. It plays a vital role in post-translational modification and is essential for the proper functioning of the cell's endomembrane system.

budding process

Vesicle formation is a cellular process where small, membrane-bound sacs are created to transport molecules within or outside the cell. This process is crucial for maintaining cellular organization, facilitating communication, and regulating the distribution of proteins and lipids.

Cargo selection involves choosing the most appropriate goods for transportation based on factors such as cost, efficiency, and destination requirements. This process is crucial for optimizing logistics operations and ensuring timely delivery while minimizing risks and maximizing profitability.
