The rough endoplasmic reticulum (rough ER) is primarily involved in the synthesis and processing of proteins. Its surface is studded with ribosomes, which are the sites of protein translation. Once proteins are synthesized, they enter the rough ER for folding, modification, and transport to other parts of the cell or for secretion. Additionally, the rough ER plays a role in the production of membranes and other cellular components.
