The human proteostasis network is operationally defined by providing a comprehensive, annotated, and manually curated list of its components classified into nine Branches based on their function and localization - cytonuclear proteostasis, ER proteostasis, mitochondrial proteostasis, nuclear proteostasis, proteostasis network regulation, translation, extracellular proteostasis, and the autophagy-lysosome pathway.
The condition of having a healthy, functional proteome is known as protein homeostasis, or proteostasis. Establishing and maintaining proteostasis is the province of the proteostasis network, a highly interconnected system of over 3000 components that regulate protein synthesis, folding, localization, and degradation....

Abstract Disruption of protein homoeostasis, or proteostasis, is a hallmark of protein conformational diseases (PCDs), including Alzheimer's and Parkinson's disease. These disorders are characterized by progressive protein aggregation and cellular dysfunction, yet no effective therapies exist. Emerging evidence indicat...

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...

Abstract Sequestosome 1 (SQSTM1 or p62) is a multi-domain protein that functions as a scaffold for aggregating proteins into cytoplasmic inclusions and mediating their turnover via selective autophagy. However, p62 is more than an autophagy scaffold or adaptor protein; it’s linked with endo/exosomal protein trafficking...

Protein homeostasis, or proteostasis, is essential for cellular health, and its disruption contributes to cancer, aging, and neurodegenerative disease. Proteostasis is maintained largely by two intracellular degradation systems: the ubiquitin proteasome system (UPS) and the autophagy lysosomal pathway (ALP). Here, we c...
