Any cellular protein that binds to an unfolded or partially folded target protein to prevent misfolding, aggregation, and/or degradation of it. Chaperones also facilitate the target protein's proper folding, translocation and assembly within cells, preventing inappropriate interactions with other proteins.

Collective term for two types of proteins that prevent misfolding of a target protein (molecular chaperones) or actively facilitate its proper folding (chaperonins). ( Figure 3-15)

A protein that facilitates the proper folding of other proteins but does not bind to their final folded form.

A protein that binds newly synthesized polypeptide chains to prevent incorrect folding during transport to protein assembly sites.

A protein that facilitates the folding of other proteins or assembly of multi-protein complexes.

Protein that helps other proteins avoid misfolding pathways that produce inactive or aggregated states.

a protein that assist the correct folding of other cellular proteins into their active conformation

Any of a class of proteins that helps proteins fold or escorts proteins or other molecules throughout the cell.

A protein that assists the correct non-covalent assembly of folding proteins in vivo; chaperones do not themselves form part of the structures they help to assemble.

a molecule which controls the three dimensional folding and transport of another molecule.
