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
This hypothesis integrates kinetic modeling of chaperone disaggregation capacity with targeted enhancement of protein clearance through CHIP-mediated degradation coupling. The mechanism centers on the critical kinetic parameters governing Hsp70/DNAJB1 chaperone system performance, specifically the maximum velocity (Vmax) representing peak disaggregation capacity and the Km reflecting chaperone-substrate binding affinity. Under normal conditions, the chaperone system operates below saturation, ef
