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

Drug-target residence time (tau), one of the main determinants of drug efficacy, remains highly challeng-ing to predict computationally and, therefore, is usually not considered in the early stages of drug de-sign. Here, we present an efficient computational method, tau-random acceleration molecular dynamics (tauRAMD), for the ranking of drug candidates by their residence time and obtaining insights into ligand-target dissociation mechanisms. We assessed tauRAMD on a dataset of 70 diverse drug-like ligands of the N-terminal domain of HSP90alpha, a pharmaceutically important target with a highly flexible binding site, obtaining computed relative residence times with an accuracy of about 2.3tau for 78% of the compounds and less than 2.0tau within congeneric series. Analysis of dissociation trajectories reveals features that af-fect ligand unbinding rates, including transient polar interactions and steric hindrance. These results sug-gest that tauRAMD will be widely applicable as a computationally efficient aid to improving drug resi-dence times during lead optimization.
