FunctionNEDD8_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.[1] [2] [3] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedNedd8, a ubiquitin-like modifier, is covalently attached to various proteins. Although Nedd8 has higher sequence identity (57%) with ubiquitin, its conserved K48 residue cannot form covalent linkage with ubiquitin. To decipher the reason why Nedd8 cannot be an effective ubiquitin-acceptor, we compared the non-covalent interaction between Nedd8 and ubiquitin for various E2s using cross-saturation NMR technique. However, both Nedd8 and ubiquitin displayed almost identical non-covalent E2-binding properties. The K60 of Nedd8 was not present at the E2-binding surface, but its mutation to Asn converted Nedd8 into a ubiquitin-acceptor. The N60 ubiquitin mutants also displayed a decreased ubiquitin-accepting activity. These results suggest the presence of an uncharacterized determinant for the K48 ubiquitin-linkage that is not related to non-covalent E2-bindings. 60th residues of ubiquitin and Nedd8 are located out of E2-binding surfaces, but are important for K48 ubiquitin-linkage.,Choi YS, Jeon YH, Ryu KS, Cheong C FEBS Lett. 2009 Oct 20;583(20):3323-8. Epub 2009 Sep 24. PMID:19782077[4] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
