Proteins

Atlas Image
The N-terminal amino acids from 1-153 contains most of the functional domains consisting of the Kinetochore binding domain, Mad2 binding domain and the Anaphase promoting complex (APC) activation domain. Amino acids 129-499 contain the WD-repeat region.

Description

Size: 499 amino acids; 54723 Da. Subunit: Interacts with MAD2L1. The phosphorylated form interacts with APC/C. Developmental stage: Synthesis is initiated at G1/S, protein level peaks in M phase and protein is abruptly degraded at M/G1 transition.

Expression

It is expressed in all cells, no tissue specificity.

Nucleus

Function

CDC20 is a key player in the Spindle Assembly Checkpoint (SAC). When a cell is dividing mitotically, the Metaphase to Anaphase transition is stringently monitored by SAC. After proper alignment of all the sister chromatids to the spindle fibers during metaphase, the Mitotic Checkpoint Complex detaches from CDC20 and free CDC20 protein activates the Anaphase promoting Complex (APC) Activated APC can then degrade Securin which frees the protease Separase. Free Separase can now degrade the Cohesin molecules binding the two sister chromatids together. Upon degradation of Cohesin, the two sister chromatids are free and can migrate to the two spindle poles, thus, initiating Anaphase.

Homology

The C-terminal half is highly conserved from humans to yeast.
