Promotion of NEDD8-CUL1 Conjugate Cleavage by COP9 Signalosome

Svetlana Lyapina,1 Gregory Cope,1 Anna Shevchenko,3* Giovanna Serino,4 Tomohiko Tsuge,4 Chunshui Zhou,5 Dieter A. Wolf,5 Ning Wei,4 Andrej Shevchenko,3* Raymond J. Deshaies12dagger

SCF ubiquitin ligases control various processes by marking regulatory proteins for ubiquitin-dependent proteolysis. To illuminate how SCF complexes are regulated, we sought proteins that interact with the human SCF component CUL1. The COP9 signalosome (CSN), a suppressor of plant photomorphogenesis, associated with multiple cullins and promoted cleavage of the ubiquitin-like protein NEDD8 from Schizosaccharomyces pombe CUL1 in vivo and in vitro. Multiple NEDD8-modified proteins uniquely accumulated in CSN-deficient S. pombe cells. We propose that the broad spectrum of activities previously attributed to CSN subunits--including repression of photomorphogenesis, activation of JUN, and activation of p27 nuclear export--underscores the importance of dynamic cycles of NEDD8 attachment and removal in biological regulation.
