WebVirtually all eukaryotic processes are regulated by cullin-RING E3 ligase (CRL)-catalyzed protein ubiquitylation1, which is exquisitely controlled by cullin modification with the ubiquitin (UB)-like protein NEDD82-6. However, how CRLs catalyze ubiquitylation, and the basis for NEDD8 activation, remain unknown. We report the WebCullin. Cullins are a family of hydrophobic scaffold proteins which provide support for ubiquitin ligases (E3). All eukaryotes appear to have cullins. They combine with RING proteins to form Cullin-RING ubiquitin ligases (CRLs) that are highly diverse and play a role in myriad cellular processes, most notably protein degradation by ubiquitination.
