Protein misfolding and protein aggregation are causes of severe diseases
as neurodegenerative disorders, diabetes and cancer. Therefore, the cell
has to constantly monitor the folding status of its proteome. Chaperones
and components of the ubiquitin-proteasome system are key players in the
cellular protein quality control process. In order to characterize
components of the protein quality control system in a well-established
model eukaryote - the yeast Saccharomyces cerevisiae - we established
new cytosolic model substrates based on firefly luciferase and
(beta-isopropylmalate dehydrogenase (Leu2). The use of these two
different enzymes arranged in tandem as reporters enabled us to analyse
the folding status and the degradation propensity of these new model
substrates in yeast cells mutated in components of the cellular protein
quality control system. The Hsp70 chaperone system known to be essential
in the cellular protein quality control was chosen as a model for
showing the high value of the luciferase-based model substrates in the
characterization of components of the cytosolic protein quality control
system in yeast. (C) 2016 Elsevier Inc. All rights reserved.
