==GELDANAMYCIN BOUND TO THE HSP90 GELDANAMYCIN-BINDING DOMAIN==
-
The Hsp90 chaperone is required for the activation of several families of, eukaryotic protein kinases and nuclear hormone receptors, many of which, are protooncogenic and play a prominent role in cancer. The geldanamycin, antibiotic has antiproliferative and antitumor effects, as it binds to, Hsp90, inhibits the Hsp90-mediated conformational maturation/refolding, reaction, and results in the degradation of Hsp90 substrates. The, structure of the geldanamycin-binding domain of Hsp90 (residues 9-232), reveals a pronounced pocket, 15 A deep, that is highly conserved across, species. Geldanamycin binds inside this pocket, adopting a compact, structure similar to that of a polypeptide chain in a turn conformation., This, and the pocket's similarity to substrate-binding sites, suggest that, the pocket binds a portion of the polypeptide substrate and participates, in the conformational maturation/refolding reaction.

== Function ==
 +
[https://www.uniprot.org/uniprot/HS90A_HUMAN HS90A_HUMAN] Molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved for instance in cell cycle control and signal transduction. Undergoes a functional cycle that is linked to its ATPase activity. This cycle probably induces conformational changes in the client proteins, thereby causing their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.<ref>PMID:15937123</ref> <ref>PMID:11274138</ref>
