Function

[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.^[1] ^[2]

Publication Abstract from PubMed

Two novel series of oxazepine and diazepine based HSP90 inhibitors are reported. This effort relied on structure based design and isothermal calorimetry to identify small drug like macrocycles. Computational modelling was used to build into a solvent exposed pocket near the opening of the ATP binding site, which led to potent inhibitors of HSP90 (25-30).
