The protein will first travel from the ER to the Golgi apparatus, where it will be modified and sorted into vesicles. These vesicles can then transport the protein to various destinations, including other organelles, the plasma membrane, or outside the cell through exocytosis. Therefore, it can end up in the lumen of the Golgi apparatus, the lumen of a vesicle, or outside the cell.
