The cell's ability to self-reproduce is a fundamental feature of life, essential for species continuation and embryonic development, as well as tissue renewal in adult organisms, including humans. Cellular self-reproduction reflects the workings of the cell division cycle machinery, whose two major driving forces, the activities of cyclin-dependent kinases (CDKs) and ubiquitin-mediated, proteasome-dependent proteolysis, are carefully orchestrated at multiple levels.
