Hsp104 also remodels amyloid in vitro and promotes propagation of amyloid prions in yeast, but ClpB does neither, leading to a view that Hsp104 evolved these activities. Although biochemical analyses identified disaggregation machinery components required for resolubilizing proteins, interactions among these components required for in vivo functions are not clearly defined. We express prokaryotic chaperones in yeast to address these issues and find ClpB supports both prion propagation and thermotolerance in yeast if it is modified to interact with yeast Hsp70 or if E. coli Hsp70 and its cognate nucleotide exchange factor (NEF) are present. Our findings show prion propagation and thermotolerance in yeast minimally require cooperation of species-specific Hsp100, Hsp70, and NEF with yeast Hsp40. The functions of this machinery in prion propagation were directed primarily by Hsp40 Sis1p, while thermotolerance relied mainly on Hsp40 Ydj1p. Our results define cooperative interactions among these components that are specific or interchangeable across life kingdoms and imply Hsp100 family disaggregases possess intrinsic amyloid remodeling activity."xsd:string |
