Pdf most proteins must fold into defined threedimensional structures to gain functional activity. Pdf molecular chaperones in protein folding and proteostasis. An everincreasing number of intrinsically disordered proteins and. Molecular chaperones operate by binding to stabilize an otherwise unstable structure of a protein in its folding pathway, but chaperones do not contain the necessary information to know the correct native structure of the protein they are aiding. The folding of many newly synthesized proteins in the cell depends on a set of conserved proteins known as molecular chaperones. Molecular chaperones are a ubiquitous class of folding modulators that play a central role in the conformational quality control of the proteome by interacting with, stabilizing and remodeling a wide range of nonnative polypeptides.
