The article cites a study conducted by researcher Judith Frydman published in the June 3, 2005 issue of "Cell" which shows that distinct chaperone pathways control the decision between either folding or degrading cytoplasmic proteins. Misfolded proteins can be refolded or they can be degraded by the ubiquitin-proteasome pathway. Protein chaperones are important for both processes. In the endoplasmic reticulum, two different chaperones sort proteins into folding or degradation pathways. Addressing this question in yeast with a mutant von Hippel-Lindau protein that is folding-defective and unstable.

    HAP46/BAG-1M and its isoforms affect the protein-folding activities of mammalian HSP70 chaperones. They interact with the ATP-binding domain of HSP70 or HSC70, leaving the substratebinding site available for further interactions. Trimeric complexes can therefore form with, for example,...

    Protein structures are much more conserved than sequences during evolution. Based on this observation, we investigate the consequences of structural conservation on protein evolution. We study seven of the most studied protein folds, determining that an extended neutral network in sequence space...
