Monoclonal Mouse Affinity Purified E B IP
In yeast, proteolysis of G1 cell cycle regulatory proteins is controlled by a ubiquitin ligase formed by three subunits: Cdc53 (also known as CulA), Skp1 and one of many F-box proteins (reviewed in ref 2). A C. elegans family of cullin genes homologous to the S. cerevisiæ cdc53 gene has been identified (cul1, 2, 3, 4, and 5) (2). The C. elegans cul1 null mutant shows a shortened G1 phase and a generalized hyperplasia, suggesting that Cul1 may be involved in the degradation of positive cell cycle regulators (e.g., G1 cyclins as in S. cerevisiæ). These findings suggest that during evolution the cdc53 gene diverged into at least five different genes, of which some may have specialized in the ubiquitination of specific proteins (e.g., cyclins) and others in the ubiquitination of other proteins (e.g., Cdk-inhibitors). A family of 6 human cullin genes (cul1,2, 3, 4a, 4b, and 5) has also been identified. It was then shown that Cul1 forms a complex with human Skp1 and the F box protein Skp2. This complex is thought to play a role in the ubiquitination of G1 regulatory proteins as its homolog does in yeast.
