Cloned(Commentary)

Cloned (Comment) Organism
expressed in HEK-293T cells Homo sapiens

Protein Variants

Protein Variants Comment Organism
S1126A the mutation prevents the conformational change of the enzyme caused by phosphorylation, thereby rendering separase resistant to precipitation in mitosis Homo sapiens

Inhibitors

Inhibitors Comment Organism Structure
cyclin-dependent kinase 1-cyclin B1 Cdk1-cyclin B1 triggers precipitation of separase by phosphorylation but stabilizes it by inhibitory binding. Only separase that is first complexed by Cdk1-cyclin B1 can later be activated by cyclin B1 degradation Homo sapiens
