== Function ==
[https://www.uniprot.org/uniprot/AHA1_YEAST AHA1_YEAST] Co-chaperone that binds to the molecular chaperone HSP82 and stimulates its ATPase activity. Binding to HSP82 promotes a conformational switch in the catalytic loop of HSP82, facilitating the interaction of the catalytic 'Arg-380' with ATP in the N-terminal nucleotide-binding domain. Although not essential, it confers thermotolerance when intracellular levels of HSP82 are limiting.<ref>PMID:12504007</ref> <ref>PMID:12604615</ref>
