Abstract: To be, or not to be — that is the question not only for Hamlet in Shakespeare’s drama but also for a protein associated with molecular chaperones. While long viewed exclusively as cellular folding factors, molecular chaperones recently emerged as active participants in protein degradation. This places chaperones at the center of a life or death decision during protein triage. Here we highlight molecular mechanisms that underlie chaperone action at the folding/degradation interface in mammalian cells. We discuss the importance of chaperone-assisted degradation for the regulation of cellular processes and its emerging role as a target for therapeutic intervention in cancer and amyloid diseases.

Molecular chaperones in protein folding and proteostasis
TL;DR: It is suggested that an age-related decline in proteostasis capacity allows the manifestation of various protein-aggregation diseases, including Alzheimer's disease and Parkinson's disease, which may spring from a detailed understanding of the pathways underlying proteome maintenance.
Molecular Chaperone Functions in Protein Folding and Proteostasis
TL;DR: This review focuses on recent advances in understanding the mechanisms of chaperone action in promoting and regulating protein folding and on the pathological consequences of protein misfolding and aggregation.

The proteostasis network and its decline in ageing.
TL;DR: The possibilities of pharmacological augmentation of the capacity of proteostasis networks hold great promise for delaying the onset of age-related pathologies associated with proteome deterioration and for extending healthspan.

TL;DR: The findings reveal the importance of chaperone-assisted degradation for the preservation of cellular structures and identify muscle as a tissue that highly relies on an intact proteostasis network, thereby shedding light on diverse myopathies and aging.

Protein aggregation and neurodegenerative disease
TL;DR: The most likely explanation is that inclusions and other visible protein aggregates represent an end stage of a molecular cascade of several steps, and that earlier steps in the cascade may be more directly tied to pathogenesis than the inclusions themselves as discussed by the authors.

Aggresomes, inclusion bodies and protein aggregation.
TL;DR: This work has suggested that, in animal cells, aggregated proteins are specifically delivered to inclusion bodies by dynein-dependent retrograde transport on microtubules and this microtubule-dependent inclusion body is called an aggresome.

TL;DR: It is shown that ubiquitinated DRiPs are formed from human immunodeficiency virus Gag polyprotein, a long-lived viral protein that serves as a source of antigenic peptides.

Hsp90 as a capacitor of phenotypic variation
TL;DR: It is reported that, in Arabidopsis accessions and recombinant inbred lines, reducing Hsp90 function produces an array of morphological phenotypes, which are dependent on underlying genetic variation, and that HSp90 influences morphogenetic responses to environmental cues and buffers normal development from destabilizing effects of stochastic processes.
