== Function ==
 +
[https://www.uniprot.org/uniprot/NEDD8_HUMAN NEDD8_HUMAN] Ubiquitin-like protein which plays an important role in cell cycle control and embryogenesis. Covalent attachment to its substrates requires prior activation by the E1 complex UBE1C-APPBP1 and linkage to the E2 enzyme UBE2M. Attachment of NEDD8 to cullins activates their associated E3 ubiquitin ligase activity, and thus promotes polyubiquitination and proteasomal degradation of cyclins and other regulatory proteins.<ref>PMID:10318914</ref> <ref>PMID:10597293</ref> <ref>PMID:11953428</ref>

== Publication Abstract from PubMed ==
 +
The Nedd8 conjugation pathway is conserved from yeast to humans and is essential in many organisms. Nedd8 is conjugated to cullin proteins in a process that alters SCF E3 ubiquitin ligase activity, and it is presumed that Nedd8 deconjugation would reverse these effects. We now report the X-ray structures of the human Nedd8-specific protease, Den1, in a complex with the inhibitor Nedd8 aldehyde, thus revealing a model for the tetrahedral transition state intermediate generated during proteolysis. Although Den1 is closely related to the SUMO-specific protease family (Ulp/Senp family), structural analysis of the interface suggests determinants involved in Nedd8 selectivity by Den1 over other ubiquitin-like family members and suggests how the Ulp/Senp architecture has been modified to interact with different ubiquitin-like modifiers.
