HSP90 inhibitors can target many oncoproteins simultaneously, but none have made it through clinical trials due to dose-limiting toxicity and induction of heat shock response, leading to clinical resistance. We identified diptoindonesin G (dip G) as an HSP90 modulator that can promote degradation of...
Complex conformational dynamics are essential for the chaperone function of heat shock protein 90 (Hsp90), including transient, ATP-biased N-domain dimerization establishing ATPase competence. Biochemical data demonstrate that the intrinsic, but weak, ATP hydrolyzing activity of Hsp90 is markedly en...
