| Annotation description: | Similar to ubiquitylation, neddylation requires three sequential reaction steps accomplished by the heterodimeric E1-activating enzyme NAE (Nedd8 activating enzyme), the conjugating enzyme Ubc12 and an as yet incompletely characterized set of E3 ligases (PMID:18793140). Figure 2: Inhibition of neddylation blocks spine maturation. shRNA knockdown of Ubc12 in DIV12 mouse hippocampal neurons strongly decreased dendritic spine density and increased the number of dendritic filopodia. Figure 2,3: knockdown of Ubc12 and using NAE inhibitor MLN-4924 (Fig. S2c & PMID:19360080) also reduced dendritic spine maturation. Figure 4: Neddylation is active in synapses, as demonstrated by live imaging experiments that quantified the rates of de novo growth and elimination of spines in mature cultured neurons (DIV19) treated for 8 h with vehicle or MLN-4924. Figure 6, 7: molecular characterization of PSD95 (DLG4) neddylation further confirms this process takes place at the postsynapse. |
