separase a caspase-like protease, which plays a central role in the chromosome segregation by cleaving the SCC1/RAD21 subunit of the cohesin complex at the onset of anaphase. During most of the cell cycle, it is inactivated by different mechanisms. Regulated by at least two independent mechanisms. First, it is inactivated via its interaction with securin/PTTG1, which probably covers its active site. Second, phosphorylation inactivates it. It is completely phosphorylated during mitosis and dephosphorylated during anaphase. Two alternatively spliced isoforms have been described.
