... substitution of these two arginines. We map the site of binding of Ube4b to the N-domain of VCP and show that it competes for this site with Hrd1. Finally, we investigate the evolutionary divergence of ... evolutionary divergence in the molecular architecture of VCP–Cdc48p-containing complexes in ERAD, despite conservation of the princi- ple of VCP–Cdc48p binding.

... studied the evolutionary conservation of DDIs by comparing the DDI repertoires of the organisms. To evaluate the statistical significance, we generated 1000 random DDI networks for each of the five ... DDIs between all pairs of organisms. Again, most of the DDIs of yeast, worm, and fly are shared with either E. coli or human, because many of the DDIs were taken from structur...
