Abstract

Heider et al. investigate the molecular function of immunomodulatory drugs (IMiDs) and describe their target, CRBN, as a transmembrane protein (TP)-specific co-chaperone of the HSP90-AHA1 axis. By disrupting CRBN-HSP90 interaction, IMiDs lead to destabilization of various TPs as CD98hc/LAT1, which serve as therapeutic targets in multiple myeloma.
