The cellular clearance of amyloidogenic oligomers operates through a two-stage molecular recognition system where exposed β-sheet propensity sequences serve as both HSP70 binding codes and conformational switches for CHIP-mediated degradation. When amyloidogenic proteins misfold into oligomeric intermediates, cryptic hydrophobic stretches (5-15 residues) with high β-sheet forming propensity become solvent-accessible and are recognized by the substrate-binding domain of HSPA8. This initial recogn
## **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
