Mutations that change the amino acid sequence of a polypeptide often result in the production of a defective protein. Defective proteins fail to function normally, most often because they fold improperly, forming an unstable or improper structure. Where does protein folding (and identification of misfolded proteins) occur, and which molecules are involved?

Misfolded proteins are identified in the nucleus, where they are bound by molecules called histones.

Misfolded proteins are identified in the Golgi apparatus, where they are bound by molecules called chaperones.

Misfolded proteins are identified in the nucleus, where they are bound by molecules called chaperones.

Misfolded proteins are identified in the ER, where they are bound by molecules called chaperones.
