Question

Quizplus · Accepted Answer

Proteolysis is the process responsible for cleaving the signal sequence from a protein after it has been directed to its proper location, such as the rough endoplasmic reticulum (RER). If a protein inappropriately moves back into the RER because its signal sequence is still attached, it indicates a failure in the proteolysis process, which should have removed the signal sequence.
