Significantly, most of the LIN Es in the human genome are located in AT-rich regions of the chromosomes, far from genes, and therefore far from the DNA quality control machinery that attend to the genes'swell-being and mighthery to sniff thumanut and eliminate them.
The mitochondrial quality control machinery is affected in aging and especially in PD, thus affecting intraneuronal protein transport and degradation, which are primarily responsible for accumulation of misfolded proteins and mitochondrial damage in sporadic as well as familial PD.
As such, care needs to be taken to avoid further saturating the quality control machinery.
Remarkably, these signals are interpreted by the quality control machinery to use the ERAD pathway under normal conditions.
Misfolded proteins are generally recognised by cellular quality control machinery, which typically results in their ubiquitination and degradation.
Misfolded proteins that were destined for lysosomes accumulate in the ER, and these are rapidly degraded by the cellular quality control machinery [45].
Therefore, at least in the two investigated mutants, there is a correlation between AOX dependent respiration and elevated levels of components of the molecular quality control machinery.
Upon folding, native proteins can exit the ER by the secretory pathway, whereas misfolded proteins and incompletely assembled protein complexes are generally retained by a protein quality control machinery [1].
In the present work we show that maize TGase (TGZ) displays an intrinsic propensity to form aggregates displaying amyloid-like features when it is refolded in vitro in the absence of the components of the protein quality control machinery.
The analysis of components of the quality control machinery by Western blot detection showed that grisea and PaCox17::ble seem to contain more LON protease and HSP60 than the WT.
Intracellular protein aggregates are formed when misfolded polypeptides accumulate in the cells due to malfunctioning or overloading of the protein quality control machinery or of the components of the degradative pathway [4].
