Hsp104 is molecular chaperone in the AAA+ family of ATPases that specializes in the resolubilization and refolding of thermally denatured proteins in yeast. In addition to providing high levels of thermotolerance, Hsp104 plays a pivotal role in the propagation of yeast prions, self-replicating, amyloid-like aggregates that are inherited during mitosis and meiosis. In this review, the structure and function of Hsp104 is discussed, its functional interaction with other molecular chaperones, and a model for disaggregation and refolding is proposed.
