Which of the following is the group of proteins which are essential for the 'folding' of other proteins in a cell?
Some proteins need to interact with various polypeptides to attain correct folded shapes. These helper peptides are called molecular chaperones. Molecular chaperones comprise a great variety of proteins that are essential for protein binding and translocation across cellular compaments, assembling multi-protein complexes, preventing aggregation, and directing mis-folded and sho-lived proteins to degradation by the proteosome.
