Q-bodies monitor the quinary state of the protein fold

Nat Cell Biol. 2013 Oct;15(10):1137-9. doi: 10.1038/ncb2857.

Abstract

Cytoplasmic compartments containing misfolded proteins targeted for degradation, named Q-bodies, have been identified. Q-body formation is a dynamic process that actively manages the metastable state of the protein fold through small heat shock proteins and the Hsp70-Hsp90-Hsp110 proteostasis system to promote cellular fitness under both physiological and stress conditions.
