Regulated by checkpoint proteins such as Mad2 and BubR1, Cdc20 safeguards chromosome segregation, while its dysregulation contributes to aneuploidy and cancer progression.

The G1, G2 and spindle checkpoints prevent cells with damage or misaligned chromosomes from dividing, ensuring accurate genome transmission and protecting against genomic instability and cancer.
