Target Background

Function
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.
Gene References into Functions
  1. A chemical compound inhibiting the Aha1-Hsp90 chaperone complex PMID: 28851842
  2. The work here suggests that both Hch1p and Aha1p regulate Hsp90 function through interaction with the catalytic loop but do so in different ways. PMID: 24726918
  3. Aha1 facilitates the progression of the Hsp90 co-chaperone cycle. PMID: 23396352
  4. an interaction between Aha1 and residues near the C terminus of Mal63 PMID: 20177068
  5. For maximum activation of Hsp90, the two domains of Aha1 bind to sites in the middle and N-terminal domains of Hsp90 in a sequential manner. PMID: 20159554
  6. binding of N-Aha1 promotes a conformational switch in the middle-segment catalytic loop (370-390) of Hsp90 that releases the catalytic Arg 380 PMID: 15039704
