  • ubiquitin family
  • CATEGORY regulatory
    SUBCELLULAR LOCALIZATION     intracellular
    basic FUNCTION
  • acting as an ubiquitin-like protein playing an important role in cell cycle control and embryogenesis
  • regulating cell-cycle progression (targeting of katanin for degradation during transition from meiosis to mitosis)
  • involved in protecting a subset of ribosomal proteins from destabilization
  • interplay between NEDD8 and ubiquitin pathways operating in diverse cellular stress conditions
  • NEDD8 modification potentiates parkin E3 ligase activity
  • conserved role for NEDD8 in linking cullin-RING ubiquitin ligases (CRLs) ubiquitin ligase function to the VCP pathway
  • modifies cullin-RING ubiquitin E3 ligases
  • role of NEDD8 in regulating transcription factor stability and function
  • may play an important role in the control of proliferation and differentiation of human placenta throughout pregnancy
  • CELLULAR PROCESS cell cycle, progression
    protein, ubiquitin dependent proteolysis
  • embryogenesis
  • morphogenesis
    a component
  • covalently conjugating to cullin 2 through the complex VHL-elongin B and elongin C
    small molecule
  • ubiquitin C-terminal hydrolase, UCH-L3
  • culin 1, CUL1
  • NEDD8 Ultimate Buster-1, NUB1
  • ROC1-CUL1
  • aryl hydrocarbon receptor, AhR
  • negative regulator of ubiquitin-like proteins 1 like, NUB1L
  • ubiquitin-like protein FAT10
  • Ulp/Senp protease family member Den1
  • breast cancer-associated protein 3, BCA3
  • Cullin3, Cul3
  • crucial regulator of RPL11 signalling to TP53
  • NEDD8 is an ancillary player to regulate the stability of HIF1A
  • PRKN and PINK1 are NEDD8 conjugated
  • E2F1 is a substrate for NEDD8 post-translational modification (NEDDylation results in decreased E2F1 stability, lower transcriptional activity and slower cell growth)
  • NEDD8 is conjugated to RCAN1 (RCAN1-1S) via three lysine residues, K96, K104, and K107 (neddylation enhances RCAN1 protein stability without affecting its cellular location)
  • plays an important role in the ubiquitination of SCNN1A in alveolar epithelial cells
  • NUB1L directly interacted with NEDD8, but not with ubiquitin, on the key residue Asn-51 of NEDD8 and with VCP on its positively charged VCP binding motif
  • COPS5 acts potentially as a positive regulator of IFN responses by stabilizing IFNR through antagonizing the NEDD8 pathway
  • physically SMURF1 interacts with NEDD8 and UBE2M, forms a NEDD8-thioester intermediate, and then catalyses its own neddylation on multiple lysine residues

    activated by ubiquitin-activating (E1) enzyme

    cleavage of precursor form by UCHL3 or SENP8 is necessary for function
