The cell division cycle protein 20 homolog is an essential regulator of cell division that is encoded by the CDC20, a protein related to the beta subunit of heterotrimeric G proteins where near its N-terminus it contains seven WD40 repeats, which are multiple short, structural motifs of around 40 amino acids that often play a role in binding with larger protein complexes.
The cell division cycle protein 20 homolog is an essential regulator of cell division that is encoded by the CDC20 gene in humans.
