Genetic interactions between Ipa1 and subunits of the proteasome, the RAM (regulation of Ace2p transcription factor and polarized morphogenesis) network, the APC/C (anaphase-promoting complex), the mRNA cleavage factor, and the SCF (Skp, Cullin, F-box-containing complex) are shared by E2s (ubiquitin-conjugating enzymes) interacting with Ipa1. Negative genetic interactions are indicated by a line, the individual subunits of a complex showing a genetic interaction with Ipa1 are given in bold. The E2s that interacted with Ipa1 and have been published to have a genetic interaction with subunits of the RAM network, the APC/C, the mRNA cleavage factor, and the SCF are placed next to the line. Please note that also other E2s that did not show interaction with Ipa1 have genetic interactions with these complexes. Similarly, we omitted to indicate the genetic interactions between subunits of the proteasome with subunits of the RAM network, the APC/C, the mRNA cleavage factor, and the SCF, as well as genetic interactions between Rpn4 with subunits of the RAM network, the APC/C, and the mRNA cleavage factor.
