Pathological conformers expose 'aggregation nucleation' sequences—typically 5-15 residue hydrophobic stretches with high β-sheet propensity—that are buried in native folds but become accessible during misfolding. This recognition is mediated by HSP70 isoforms including HSPA8, HSPA1A, and their J-domain co-chaperones DNAJB6 and DNAJB2. Consistent with binding studies demonstrating that HSP70 preferentially binds α-synuclein at the N-terminal and NAC amyloidogenic regions (PMID 29463785), and that

DNAJB6 (HSP40 family) exhibits selective anti-amyloid activity distinct from DNAJB2, which favors protein refolding. Differential interaction kinetics between specific J-proteins and HSP70 create a 'client code' that preferentially engages with structured β-sheet-rich cores of pathological aggregates versus helical, solvent-exposed intermediates in normal folding trajectories.
