Neddylation (also NEDDylation) is the process by which the ubiquitin-like protein NEDD8 is conjugated to its target proteins. This process is analogous to ubiquitination, although it relies on its own E1 and E2 enzymes. No NEDD8-specific E3 has yet been identified and it is possible that the Neddylation … See more NEDD8 (neural-precursor-cell-expressed developmentally down-regulated 8) is a protein involved in the regulation of cell growth, viability and development. See more Neddylation is involved in the pathogenesis of Alzheimer's disease where its activation appears to drive neurons into apoptosis by initiating cell cycle reentry. Also, evidence … See more NEDD8 links itself to a protein through an isopeptide linkage between its carboxy-terminal glycine and the lysine of the substrate. The neddylation of the substrate causes in … See more doi:10.1371/journal.pone.0043391 See more WebBecause Myc:AXR1 cannot be efficiently separated from neddylated cullins in anti-NEDD8 immunoblots, we examined Myc:AXR1 abundance and neddylation using anti-Myc immunoblots. There, we found that increases in the NEDD8 gene dosage also led to increased multi- or polyneddylation of AXR1 (Fig. 7D, AXR1-N8 (2×), lane 6).
