Abstract

Provided herein are methods of identifying a test compound that induces a CRBN conformational change or otherwise alters the properties of a CRBN surface as defined herein, wherein conformational change or alteration has an effect on W380, W386 and/or W400 of the CRBN; has an effect on E377 of the CRBN; or has an effect on V388 of the CRBN. Also provided is a method of inducing a CRBN conformational change or otherwise altering the properties of a CRBN surface, comprising contacting the CRBN with such a test compound. Also provided is a method of identifying a substrate ubiquitinated by a E3 ubiquitination ligase complex comprising CRBN as defined herein, wherein the method comprises contacting the CRBN with said text compound. Also provided is a method of designing a test compound based on fit within CMA binding pocket of CRBN as defined herein, wherein said conformational change has an effect on W380, W386 and/or W400 of CRBN; has an effect on E377 of CRBN; or has an effect on V388 of CRBN.
