NEDDylation regulates E2F-1-dependent transcription.
The ubiquitin-like molecule NEDD8 modifies cullin-RING ubiquitin E3 ligases. NEDD8 has been shown to have a few additional substrates, but the extent to which this modification targets non-cullins and the functional significance of such modifications remain unclear. Here, we demonstrate that the cell-cycle-regulating transcription factor E2F-1 is a substrate for NEDD8 post-translational modification. NEDDylation results in decreased E2F-1 stability, lower transcriptional activity and slower c...Expand abstract
