We have identified and reconstituted a multicomponent redox-chaperone network that appears to be designed to protect proteins against stress-induced unfolding and to refold proteins when conditions return to normal. The central player is Hsp33, a redox-regulated molecular chaperone. Hsp33, which is activated by disulfide bond formation and subsequent dimerization, works as an efficient chaperone holdase that binds to unfolding protein intermediates and maintains them in a folding competent… CONTINUE READING
