| Biochem/physiol Actions: | 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. |
| Biochem/physiol Actions: | 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. |
