This chapter outlines experimental and computational strategies for MS-based analysis of the ubiquitin chaperone code, including di-glycine peptide enrichment, site identification, quantitative analysis, and validation.
Overexpression of Rpt3 enhanced proteasome assembly and activity, reducing intracellular ubiquitin levels in hac1Δ, and upregulates Hac1 protein abundance, thereby ensuring proteostasis maintenance.

Chaperone-assisted selective autophagy (CASA) is a crucial process aimed at maintaining proteostasis in several neurodegenerative diseases associated with protein misfolding, including polyglutamine (polyQ) diseases. Autophagy is a critical lysosome-mediated degradation pathway, particularly essential in neurons, which...

Abstract Proteostasis, the process governing the dynamic regulation of protein synthesis, folding and degradation, is critical for maintaining cell function and organismal health. Ageing disrupts this intricate system, leading to inactive, misfolded and/or aggregated proteins that contribute to age-associated pathologi...

SUMOylation is a reversible post-translational modification increasingly recognized for its role in coordinating cellular responses to metabolic stress during aging. Emerging evidence indicates that it functions beyond a conventional modification, representing an adaptive stress‑responsive regulatory network that integ...

Abstract Maintaining protein homeostasis (proteostasis) is crucial for long-term tissue health. This requires the action of stress response pathways and protein quality control mechanisms that act within or across different sub-cellular compartments to preserve proteome integrity. Within the cytosol/nucleus, the loss o...
