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]

Publication Abstract from PubMed

Covalent modification by Nedd8 (neddylation) stimulates the ubiquitin-protein isopeptide ligase (E3) activities of Cullins. DCN-1, an evolutionarily conserved protein, promotes neddylation of Cullins in vivo, binds directly to Nedd8, and associates with Cdc53 in the budding yeast Saccharomyces cerevisiae. The 1.9A resolution structure of yeast DCN-1 shows that the region encompassing residues 66-269 has a rectangular parallelepiped-like all alpha-helical structures, consisting of an EF-hand motif N-terminal domain and a closely juxtaposed C-terminal domain with six alpha-helices. The EF-hand motif structure is highly similar to that of the c-Cbl ubiquitin E3 ligase. We also demonstrate that DCN-1 directly binds to Rbx-1, a factor important for protein neddylation. The structural and biochemical results are consistent with the role of DCN-1 as a scaffold protein in a multisubunit neddylation E3 ligase complex.
