WebAbstract: Cullin-RING E3 ligases (CRLs) are the largest family of E3 ubiquitin ligases, responsible for about 20% of the protein degradation by the ubiquitin-proteasome system (UPS). Given their vital roles in multiple cellular processes, and over-activation in many human cancers, CRLs are validated as promising targets for anti-cancer therapies. WebThe immunomodulatory drug (IMiD) thalidomide and its structural analogs lenalidomide and pomalidomide are highly effective in treating clinical indications. Thalidomide binds to cereblon (CRBN), a substrate receptor of the cullin-4 really interesting new gene (RING) E3 ligase complex.
WebThe E3 ubiquitin ligases, based upon their structure, can be further categorized into 4 classes, including the N-end rule E3s, HECT-E3s, RING-E3s, and APC/C E3s. The RING-E3s can further be subdivided into RING-containing single peptide E3s. Cullin-RING ligases (CRLs) and its derivatives. U-box E3s. THE COMPOSITION OF CRL E3s WebOct 1, 2024 · CRLs are modular complexes composed of Cullin scaffold proteins that bind RBX1 (RING BOX1) at their C-termini and different substrate receptors at their N-termini (Figure 2a–c) [32]. In plants, CRL complexes with Cullin1 (Cul1), Cul3 and Cul4 have been described and each Cullin has specific substrate receptors: SKP1
WebThe Cullin-RING ubiquitin ligase (CRL) family, which may number as many as 350 different enzymes, has an enormous impact on cellular regulation. CRL enzymes regulate cell biology by conjugating ubiquitin onto target proteins that are involved in a multitude of processes.
