WebCdc20 is also regulated by the mitotic checkpoint kinase Bub1 in yeast (Budding uninhibited by benomyl) and its cousin Bub1R in mammals. As Cdc2 is inactive, so is APC, and hence, cells cannot enter anaphase. The spindle checkpoint includes a number of other proteins, with the list growing with evolutionary complexity.
