How does the nucleus control protein synthesis in cytoplasm
Protein Folding and formation of disulfide bridges. Processing of proteins begins with interaction of the newly made peptide with chaparone proteins in the lumen of the ER. Chaparone proteins are released as the protein assumes its proper configuration. For many secreted proteins (including cell surface proteins), the three dimensional structure of the protein is supported by disulfide bridges that are formed between cysteine residues. It is important to keep in mind that these bonds are formed as the protein assumes its folded structure. The enzyme protein disulfide isomerase is resident in the ER and facilitates formation of disulfide bridges.

Biochemical networks called signal transduction pathways convert specific patterns of synaptic transmissions into new protein synthesis. Ribosomal and RNA‐binding proteins are common targets of these pathways.

Protein folding in the endoplasmic reticulum Protein synthesis
The latter proteins are inserted into the lumen of the RER, carbohydrates are added to them to produce glycoproteins, and they are then moved to cis face of the Golgi apparatus in transport vesicles that bud from the ER membrane.

Free ribosomes synthesize the proteins that function in the cytosol, while bound ribosomes make proteins that are distributed by the membrane systems, including those which are secreted from the cell.

In protein synthesis the mRNA (messenger RNA) moves through the ribosome while amino acids attached to tRNAs (transfer RNAs) are brought to the ribosome.
