Hsp90 co-chaperone AHA1

UniProtKB accession:  Q12449

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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.
