This hypothesis proposes that HSP70's recognition of exposed β-sheet propensity sequences in amyloidogenic proteins serves as the molecular trigger for CHIP-mediated selective degradation of pathological oligomers. When amyloidogenic segments (typically 5-15 hydrophobic residues with high β-sheet propensity) become exposed during protein misfolding, they are recognized by HSPA8's substrate-binding domain through their distinct physicochemical properties. This recognition event induces a specific
## **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
