A protein that is destined to be excreted from the cell that is making it

Question

Quizplus · Accepted Answer

Proteins that are destined to be excreted from the cell, such as hormones or enzymes, have signal sequences that direct them to the endoplasmic reticulum (ER), where the protein and the ribosome to which it is attached are transported to the ER membrane. This process is called co-translational translocation. Once the protein is transferred into the ER lumen, it can then be transported to the Golgi apparatus for further processing and sorting before being excreted from the cell.
