**Molecular Mechanism and Rationale**
The carboxy terminus of Hsc70-interacting protein (CHIP, encoded by STUB1) functions as a critical E3 ubiquitin ligase that bridges molecular chaperones to the ubiquitin-proteasome system (UPS), facilitating the selective degradation of misfolded proteins. CHIP contains an N-terminal tetratricopeptide repeat (TPR) domain that binds to the C-terminal EEVD motifs of HSP70 (HSPA8) and HSP90, while its C-terminal U-box domain confers E3 ubiquitin ligase activit

## **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
