The ubiquitination process is mediated sequentially by three classes of enzymes consisting of a Ub-activating enzyme E1, a Ub-conjugating enzyme E2, and a Ub ligase E3. Ub is first activated by E1 in an adenosine 5′-triphosphate (ATP)-dependent manner t |

We then examined the effect of necdin on ubiquitin-dependent degradation of PGC-1α using Rnf34, a PGC-1α E3 ubiquitin ligase22. Rnf34 reduced the PGC-1α level, and necdin completely inhibited the reduction (Fig. 4i). In addition, necdin strongly suppressed Rnf34-mediated ubiquitination of PGC-1α (Fig. 4j). Necdin also protected PGC-1α against ubiquitination mediated by Fbxw7, another PGC-1α E3 ubiquitin ligase23 (Fig. 4k). These data indicate that necdin stabilizes PGC-1α by inhibiting its degradation in the ubiquitin-proteasomal system. |

Mechanistically, PGC1α was phosphorylated at serine (S) 636 by DNA-dependent protein kinase in response to irradiation. Phosphorylation at S636 promoted the degradation of PGC1α by facilitating its binding to the E3 ligase RNF34. |
