Comparing 2 hypotheses side-by-side
The cellular quality control system operates through a sophisticated molecular recognition mechanism where distinct J-protein co-chaperone architectures serve as specialized decoders for exposed amyloidogenic segments that function as HSP70 recognition codes. When pathological misfolding occurs, cryptic hydrophobic stretches (5-15 residues) with high β-sheet propensity become solvent-accessible and serve as molecular barcodes distinguishing pathogenic conformers from native proteins. DNAJB6's un
DNAJB6 specifically recognizes and suppresses amyloidogenic β-sheet conformations shared across tau, α-synuclein, and TDP-43 aggregates. Enhanced DNAJB6 expression or small molecule activators could provide broad-spectrum protection against cross-seeding by disrupting the common structural motifs that enable heterologous nucleation.
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
