Abstract excerpt
The Cdc6 DNA replication initiation factor is targeted for ubiquitin-mediated proteolysis by the E3 ubiquitin ligase SCF(CDC4) from the end of G1phase until mitosis in the budding yeast Saccharomyces cerevisiae. Here we describe a dominant-negative CDC6 mutant that, when overexpressed, arrests the cell cycle by inhibiting cyclin-dependent kinases (CDKs) and, thus, prevents passage through mitosis. This mutant...
