Solution structure of the Wiskott-Aldrich Syndrome Protein (WASP) autoinhibited core domain complexed with (S)-wiskostatin, a small molecule inhibitor
Contents |
Overview
Current drug discovery efforts focus primarily on proteins with defined, enzymatic or small molecule binding sites. Autoregulatory domains, represent attractive alternative targets for small molecule inhibitors, because they also occur in noncatalytic proteins and because allosteric, inhibitors may avoid specificity problems inherent in active site-directed, inhibitors. We report here the identification of wiskostatin, a chemical, inhibitor of the neural Wiskott-Aldrich syndrome protein (N-WASP)., Wiskostatin interacts with a cleft in the regulatory GTPase-binding domain, (GBD) of WASP in the solution structure of the complex. Wiskostatin, induces folding of the isolated, unstructured GBD into its autoinhibited, conformation, suggesting that wiskostatin functions by stabilizing N-WASP, in its autoinhibited state. The use of small molecules to bias, conformational equilibria represents a potentially general strategy for, chemical inhibition of autoinhibited proteins, even in cases where such, sites have not been naturally evolved in a target.
