[[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>

-
HSP90 continues to be a target of interest for neurodegeneration indications. Selective knockdown of the HSP90 cytosolic isoforms alpha and beta is sufficient to reduce mutant huntingtin protein levels in vitro. Chemotype-dependent binding conformations of HSP90alpha/beta appear to strongly influence isoform selectivity. The rational design of HSP90alpha/beta inhibitors selective versus the mitochondrial (TRAP1) and endoplasmic reticulum (GRP94) isoforms offers a potential mitigating strategy for mechanism-based toxicities. Better tolerated HSP90 inhibitors would be attractive for targeting chronic neurodegenerative diseases such as Huntington's disease.
