“…It is believed that Aβ amyloidogenesis is promoted by acidic pH [64]. As previously mentioned, mildly acidic pH also allows the disassociation of clusterin's heterogeneous aggregates, releasing chaperone-active subunits [10].…”

“…Clusterin's structure has yet to be experimentally determined, but is believed to contain three long molten globule-like regions and five amphipathic α-helices, which allow for hydrophobic interactions with its client-proteins [9]. Under normal circumstances, clusterin exists in solution as heterogeneous aggregates [10]. It has been suggested that, at mildly acidic pH [10], these aggregates disassociate and the disassociated chaperone-active subunits function in an ATP-independent manner [11].…”
