Function

DCN1_YEAST Required for neddylation of cullin components of SCF-type E3 ubiquitin ligase complexes. Neddylation of cullins play an essential role in the regulation of SCF-type complexes activity. Does not act by preventing deneddylation, but rather facilitates neddylation, possibly by acting with HRT1/RBX1 to recruit the Nedd8-charged E2 UBC12 to the cullin component of SCF-type complexes.^[1]
