Function

[SENP8_HUMAN] Protease that catalyzes two essential functions in the NEDD8 pathway: processing of full-length NEDD8 to its mature form and deconjugation of NEDD8 from targeted proteins such as cullins or p53.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

NEDD8 (neural precursor cell expressed developmentally downregulated gene 8)-specific protease NEDP1 processes preNEDD8 to its mature form and deconjugates NEDD8 from substrates such as p53 and cullins. Although NEDD8 and ubiquitin are highly related in sequence and structure, their attachment to a protein leads to different biological effects. It is therefore critical that NEDP1 discriminates between NEDD8 and ubiquitin, and this requires remarkable precision in molecular recognition. To determine the basis of this specificity, we have determined the crystal structure of NEDP1 in isolation and in a transition state complex with NEDD8. This reveals that NEDP1 is a cysteine protease of the Ulp family. Binding of NEDD8 induces a dramatic conformational change in a flexible loop that swings over the C-terminus of NEDD8 locking it into an extended beta-structure optimal for catalysis. Structural, mutational and biochemical studies have identified key residues involved in molecular recognition. A single-residue difference in the C-terminus of NEDD8 and ubiquitin contributes significantly to the ability of NEDP1 to discriminate between them. In vivo analysis indicates that NEDP1 mutants perturb deNEDDylation of the tumour suppressor p53.
