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
## **Molecular Mechanism and Rationale**
The recognition of amyloidogenic protein species by the heat shock protein 70 (HSP70) chaperone network represents a sophisticated quality control mechanism that distinguishes pathological conformers from their native counterparts through the exposure of specific β-sheet propensity sequences. This molecular recognition system centers on the constitutive HSP70 isoforms HSPA8 (also known as HSC70) and the inducible HSPA1A, which function in concert with th
