Abstract
A key player in mitotic progression is a cell-cycle-regulated ubiquitin-protein ligase complex known as the anaphase-promoting complex or cyclosome (APC/C). The APC/C is part of the machinery that promotes the metaphase-anaphase transition by mediating the ubiquitin-dependent destruction of anaphase inhibitors and initiates exit from mitosis by degrading mitotic cyclins. This review describes the known components and substrates of the mitotic ubiquitination machinery and discusses how a new subfamily of proteins that contain the WD40 repeat (the Fizzy/Cdc20p family) might activate the APC/C to allow temporal differences in substrate ubiquitination during progression through mitosis.
