Exploring the binding site of C-terminal Hsp90 inhibitors

The 90 kDa heat shock protein (Hsp90) is a prominent target for anticancer drug discovery. While its N-terminal domain has been widely exploited, several lines of evidence are emerging in favor of targeting its C-terminal domain to conceive innovative drugs based on perturbation of the dimer interface. Here, we describe the application of several computational approaches useful to predict the location of the C-terminal binding site.
