  "account": "Neurodegenerative proteinopathies, characterized by unique proteins, rely on shared proteostasis machinery for folding, trafficking, and clearance. The extent to which these disorders rely on common components or merely common processes remains unclear. Researchers mapped 16 disease proteins from 12 disorders onto a fixed 990-protein proteostasis network. Surprisingly, across the 12 disorders, these proteins' neighborhoods shared specific proteins more than anticipated from process composition and connectivity. This finding held true for two disorders defined by multiple proteins. Nine proteins contributed disproportionately, and only autophagy removal significantly reduced similarity. Disruption of PRKN, HSPA8, or UBQLN2 in silico reduced path efficiency, suggesting they are potential shared network vulnerabilities. In human brain proteomes, Alzheimer's disease-zone proteins displayed greater abundance remodeling in the insoluble fraction; however, this pattern did not recur across disorders. The study reveals a component-level architecture prioritizing network-derived candidates for cross-disease functional testing.",
  "summary": "Neurodegenerative proteinopathies are defined by distinct proteins whose folding, trafficking and clearance depend on shared proteostasis machinery. Whether these disorders engage common components or only common processes has been unresolved. We mapped 16 disease proteins from 12 disorders onto a fixed 990-protein proteostasis network. Across the 12 disorders, the neighborhoods of these proteins…",
