Additional data file 1:

Species include S. cerevisiae (Sc), C. elegans (Ce), and D. melanogaster (Dm). These candidate connections included genes linked to core biological functions. New candidate members were identified for protein degradation processes, including ubiquitin-dependent protein catabolism and protein degradation via the proteasome. Additionally, candidates were linked by interactions to the ribosome, maintenance, and nuclear export. New candidate components were linked to the highly conserved RNA polymerase complex. Finally, novel associations were predicted with membrane and vesicle-based targeting proteins. These examples illustrate the capacity of the Ulysses system to reveal starting points for the study of new complexes or to orient the exploration of new candidate members of known functional units
