E3 Ubiquitin Ligase Cereblon Complex

Molecular classification
E3 Ubiquitin Ligase, Enzyme, Protein Complex
01

Overview

The E3 ubiquitin ligase cereblon complex, or CRL4^CRBN complex, is a multi-protein assembly that ubiquitinates substrate proteins, marking them for proteasomal degradation. It regulates protein homeostasis and is involved in development, disease, and drug action. Cereblon acts as a substrate receptor, with its substrate specificity being modulated by drugs like thalidomide and its analogs, which are used to treat multiple myeloma.
