Rbx1 is a subunit of the related SCF (Skp1-Cdc53/Cul1-F-box protein) and von Hippel-Lindau (VHL) tumor suppressor (elongin BC-Cul2-VHL) E3 ubiquitin ligase complexes, where it functions as a component of Cdc53/Rbx1 and Cul2/ Rbx1 modules that activate ubiquitination of target proteins by the E2 ubiquitin-conjugating enzymes Cdc34 and Ubc5 |

conjugation of RBX1 to NEDD8 substantially stimulates the reaction, by nearly 2000fold, activating both substrate-priming and chain-elongation reactions. Presence of NEDD8 coordinates ubiquitin ligation assembly |

Ubc12, a NEDD8-specific E2 conjugating enzyme, is a substrate for auto-neddylation. Protease SENP8/DEN1 counteracts Ubc12 autoneddylation, and aberrant neddylation of Ubc12 and other NEDD8 conjugation pathway components is observed in SENP8-deficient cells |
