Required for full ubiquitin ligase activity of the anaphase promoting complex/cyclosome (APC/C) and may confer substrate specificity upon the complex. Is regulated by MAD2L1: in metaphase the MAD2L1-CDC20-APC/C ternary complex is inactive and in anaphase the CDC20-APC/C binary complex is active in degrading substrates. The CDC20-APC/C complex positively regulates the formation of synaptic vesicle clustering at active zone to the presynaptic membrane in postmitotic neurons. CDC20-APC/C-induced degradation of NEUROD2 induces presynaptic differentiation. Found in a complex with CDC20, CDC27, SPATC1 and TUBG1. Interacts with SPATC1. Interacts with NEUROD2. Interacts with MAD2L1 and BUB1B. The phosphorylated form interacts with APC/C. Interacts with NINL. May interact with MAD2L2. Interacts with CDK5RAP2. Interacts with isoform 1 of NEK2. Belongs to the WD repeat CDC20/Fizzy family. Note: This description may include information from UniProtKB.
