Cereblon
Cereblon (CRBN) functions as the substrate receptor of the CRL4 E3 ubiquitin ligase, mediating protein ubiquitination and degradation[1]. Mechanistically, CRBN regulates the Wnt signaling pathway by targeting Casein kinase 1α (CK1α), a negative regulator of β-Catenin, for degradation[1]. This Wnt-dependent modulation of CRBN influences developmental and disease-relevant phenotypes in zebrafish and Drosophila models[1]. Clinically, CRBN mutations have been identified in multiple myeloma patients with extramedullary disease, conferring resistance to immunomodulatory drugs (IMiDs) and highlighting its role in drug responsiveness[2]. Notably, these mutations include a Q99 truncating mutation and an R283K point mutation, impairing CRBN-mediated anti-myeloma activity[2]. Compared with related ubiquitin ligase substrate receptors, CRBN exhibits unique specificity for neo-substrates under both IMiD-bound and unbound conditions, distinguishing its functional isoform-dependent effects[1][2]. CRBN-targeted agonists, including IMiDs, exploit this substrate specificity to induce selective protein degradation, providing a basis for experimental modulation of Wnt and cancer-related pathways[1][2]. Therefore, CRBN serves as a central regulator of ubiquitin-mediated proteostasis, bridging signal transduction, disease pathophysiology, and therapeutic interventions[1][2].
