Endoplasmic Reticulum

ID #1265

In the lecture notes, it shows a picture of a protein getting translated into the Lumen of the ER and it shows how it can go to lysosomes, secretory vesicles, plasma membrane, and the golgi body. Does that mean that once a protein is translated into the ER that it cannot just stay in the lumen of the ER?

No, one of the other things I said in discussing that slide was that you can always stay where you're made. A cytosolically-translated protein can stay in the cytoplasm, and an ER-translated protein can also stay in the ER.
