Abstract excerpt
The ordered activation of the ubiquitin protein ligase anaphase-promoting complex (APC) or cyclosome by CDC20 in metaphase and by CDH1 in telophase is essential for anaphase and for exit from mitosis, respectively. Here, we show that CDC20 can only bind to and activate the mitotically phosphorylated form of the Xenopus and the human APC in vitro. In contrast, the analysis of phosphorylated and nonphosphorylated...
