    Entry into anaphase and exit from mitosis depend on a ubiquitin-protein ligase complex called the anaphase-promoting complex (APC) or cyclosome. At least 12 different subunits were detected in the purified particle from budding yeast, including the previously identified proteins Apc1p, Cdc16p, Cdc23p, Cdc26p, and Cdc27p, Five additional subunits purified in low nanogram amounts were identified by tandem mass spectrometric sequencing, Apc2p, Apc5p, and the RING-finger protein Apc11p are conserved from yeast to humans, Apc2p is similar to the cullin Cdc53p, which is a subunit of the ubiquitin-protein ligase complex SCFCdc4 required for the initiation of DNA replication.
