  "content": "Theorist argument for 'K48/K63 ubiquitin chain balance separates causal from compensatory states in: How do ALS-linked UBQLN2 mutations affect its ubiquitylation-dependent stability and':\nThe hypothesis is mechanistically plausible because it names K48/K63 ubiquitin chain balance / stress-granule partitioning as an upstream, testable driver in neurodegeneration, not merely a downstream correlate. The stated experimental logic is: A longitudinal biomarker panel centered on K48/K63 ubiquitin chain balance can distinguish harmful mechanisms from protective adaptation. The decisive experiment is to measure K48/K63 ubiquitin chain balance before and after phase-separation modifiers in stratified models.\n\nSupporting evidence read before debate:\n- four_round_gap_debate [four_round_gap_debate]\n- Stress granule homeostasis is modulated by TRIM21-mediated ubiquitination of G3BP1 and autophagy-dependent elimination of stress granules.
