Protein Information (annotations from UniProt)

Database IDHIV0000548
UniProt IDQ12834
Primary gene name(s)CDC20
Synonym gene name(s)unknown
Protein nameCell division cycle protein 20 homolog
Protein functionRequired 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. {ECO:0000269|PubMed:9637688, ECO:0000269|PubMed:9734353, ECO:0000269|PubMed:9811605}.
