Background: CUL3/RBX1 Complex

Cullin-3 (CUL3) is a core component of multiple BCR (BTB-CUL3-RBX) E3 Ubiquitin ligase complexes that mediate the ubiquitination of several classes of signaling and structural proteins.  In the BCR complex, CUL3 serves as a scaffold that organizes one or more BTB (BR-C, Ttk and Bab, also known as a POZ domain) substrate recognition subunits with the RBX subunit and contributes to catalysis through positioning of the substrate and an E2 ubiquitin-conjugating enzyme.  Substrate specificity of a BCR ligase is determined by the BTB domain protein(s) associated with the ligase, though BTB-independent CUL3 ligase activity has been reported.  In vivo, the E3 ubiquitin ligase of the BCR complex is dependent on neddylation of the cullin subunit, though neddylation may be dispensable for some in vitro reactions.
