The chaperone-autophagy coupling hypothesis centers on the critical interaction between p62/SQSTM1 and the heat shock protein 70 (HSP70) chaperone system to prevent pathological protein aggregation through enhanced autophagic clearance via chaperone-assisted selective autophagy (CASA). Unlike proteasomal degradation, this mechanism targets larger protein complexes and early aggregation intermediates that exceed the size limitations of the 26S proteasome pore. The process involves p62's multidoma
**Molecular Mechanism and Rationale**
The therapeutic hypothesis centers on the kinetic constraints governing chaperone-mediated protein disaggregation, specifically targeting the Hsp70/DNAJB1 (Hsp40) chaperone system's interaction with pathological protein seeds. At the molecular level, this mechanism involves the highly conserved Hsp70 ATPase cycle, where ATP binding induces conformational changes in the nucleotide-binding domain (NBD) that modulate substrate affinity in the substrate-binding
