Cullins are hydrophobic scaffold proteins for E3 ubiquitin ligases. They combine with ring box proteins (RBX) to form the CRL complex.^[1] The CRL complex is essential in targeting proteins to ubiquitin-mediated destruction. Cullin-1 to 7 are part of the multi-subunit ubiquitin complex. Conjugation of cullin to NEDD8 modulates the activation of the CRL.

Cullin-1 is part of the SCF (Skp-cullin-F-box containing) complex which catalyzes the ubiquitination of proteins.^[2]
Cullin-2 is part of the ECS (Elongin-cullin-SOCS-box) complex.^[3]
Cullin-3 is part of the BTB-Cul3 complex.^[4]
Cullin-4A and 4B regulate various processes like DNA repair, chromatin remodeling and mitotic cell cycle.^[5]
Cullin-5 inhibits cellular proliferation.^[6]
Cullin-7 is a core component of a complex which mediates ubiquitination of target proteins.^[7]
