Cdc34 is an essential gene for viability in yeast. Cdc34 mediates the transition from G1 to S-phase of the cell cycle by degrading the S-phase cyclin/CDK inhibitor, SIC1 in yeast and p27(KIP1) in human. Cdc34 is also known to interact with the Skp1/Cdc53/F-box (SCF) ubiquitin ligase subunits Cul1 to degrade the NF-κB inhibitor IκBα in a phosphorylation-dependent manner.
Infected cell protein 0 of herpes simplex virus 1 was shown to bind UbcH3 and induce its degradation by promoting its polyubiquination. This resulted in increased expression of an UbcH3-target gene cyclin D1 and aided in further viral infection.

Notch signaling constitutes an evolutionarily conserved mechanism that mediates cell-cell interactions in various developmental processes. Numerous regulatory proteins interact with the Notch receptor and its ligands and control signaling at multiple levels. Ubiquitination and endocytosis followed by endosomal sorting of
