Study Notes
Functions of the Rough Endoplasmic Reticulum (RER)
- Primary site for protein synthesis due to ribosomes attached to its membrane.
- Newly synthesized proteins undergo modifications and processing including:
- Glycosylation: Addition of carbohydrate groups to proteins, which affects stability and functionality.
- Protein folding: Proper folding is crucial for the protein's functionality and activity.
- Formation of disulfide bonds: These covalent bonds stabilize the protein structure within polypeptides.
- Responsible for the transport of proteins to various locations within the cell, ensuring they reach their intended destination for further use or secretion.
