[[http://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>

A series of novel and potent small molecule Hsp90 inhibitors was optimized using X-ray crystal structures. These compounds bind in a deep pocket of the Hsp90 enzyme that is partially comprised by residues Asn51 and Ser52. Displacement of several water molecules observed crystallographically in this pocket using rule-based strategies led to significant improvements in inhibitor potency. An optimized inhibitor (compound 17) exhibited potent Hsp90 inhibition in ITC, biochemical, and cell-based assays (K(d)=1.3nM, K(i)=15nM, and cellular IC(50)=0.5muM).
