Evolutionary constraints on chaperone-mediated folding provide an antiviral approach refractory to development of drug resistance
Article Abstract:
The capacity of RNA viruses for rapid adaptation is exploited with an aim to explore the evolutionary constraints of chaperone-mediated protein folding. Chaperone Hsp90 is identified as an essential factor for folding and maturation of picornavirus capsid proteins. Results reveal tight evolutionary constraints on chaperone-mediated protein folding, which may be exploited for vital inhibition in vivo.

Systems analyses reveal two chaperone networks with distinct functions in eukaryotic cells
Article Abstract:
Molecular chaperones assist the folding of newly translated and stress-denatured proteins and that eukaryotes evolved distinct chaperone networks to carry out these functions. The emergence of a translation-linked chaperone network likely underlies the elaborate cotranslational folding process necessary for the evolution of larger multidomain proteins characteristic of eukaryotic cells.

Folding and quality control of the VHL tumor suppressor proceed through distinct chaperone pathways
Article Abstract:
An analysis of the chaperone requirement for degradation of misfolded variants of a cytosolic protein the von Hippel-Lindau (VHL) tumor suppressor reveals that distinct chaperone pathways mediate its folding and quality control. The finding suggests that a hierarchy of chaperone interactions can control the alternate fates of a cytosolic protein.
