Conversion of a soluble protein into a potent chaperone in vivo

Molecular chaperones play an important role in cellular protein-folding assistance and aggregation inhibition. As a different but complementary model, we previously proposed that, in general, soluble cellular macromolecules with large excluded volume and surface charges exhibit intrinsic chaperone activity to prevent aggregation of their connected polypeptides irrespective of the connection type, thereby contributing to efficient protein...
