Rough ER (Endoplasm Reticulum)        Structure of rough ER- Rough ER has a binding site for ribosomes, which is called the translocon. Although ribosomes bind to the translocon, they do so only temporarily as they are regularly released from the membrane. A ribosome binds to the RER when a protein-nucleic acid forms in the cytosol, which is another cell component. Protein is processed in the ER lumen by a peptidase enzyme, which removes the original signal peptide. At this point, ribosomes may return to the cytosol. Occasionally they stay with the translocons.                Function of the rough ER - The rough endoplasmic reticulum, also called the Rough ER, is involved with protein synthesis. The Rough ER works by producing proteins and helping them fold properly.               Rough ER is involved in some protein production, protein production, protein folding, quali...
