Background: CUL2/RBX1 Complex

Cullin-2 is a core component of multiple cullin-RING based "ECS" (Elongin B/C-CUL2-SOCS-box protein) E3 Ubiquitin ligase complexes that mediate the ubiquitination of proteins involved in a variety of cellular processes.  In the ECS complex, Cullin-2 serves as a scaffold that organizes the ELOB/C-associated recognition subunits with the RBX1 subunit and contributes to the catalysis through positioning of the substrate and an E2 ubiquitin-conjugating enzyme.  In vivo, the E3 ubiquitin ligase activity of the ECS complex is dependent on neddylation of the cullin subunit, though neddylation may be dispensable for some in vitro reactions.
