ESP1

Separase

2180 amino acids

Cleaves SYN1, releasing sister chromatid cohesion. Required for the release of cohesin at anaphase I and anaphase II, whereas the release of cohesin during diplotene and diakinesis occurs in a separase-independent process. Essential for embryo and endosperm development. May play a role in centromeric heterochromatin structure/formation during early meiosis, non-homologous centromere association and radial microtubule system (RMS) formation. May regulate the mitosis-specific cyclin CYCB1-1.

ESP1

Separin

1630 amino acids

Caspase-like protease, which plays a central role in the chromosome segregation by cleaving the MCD1/SCC1 subunit of the cohesin complex at the onset of anaphase. During most of the cell cycle, it is inactivated by securin/PDS1 protein. It also promotes anaphase spindle elongation. A component of the FEAR (CDC14 early anaphase release) network which promotes CDC14 release from the nucleolus during early anaphase. Cleaves SLK19.

Male-specific phermone which is recognized by the Vmn2r116/V2rp5 receptor in the vomeronasal organ (VNO) and enhances female sexual receptive behavior (lordosis) upon male mounting, resulting in successful copulation.

Belongs to the exocrine gland-secreted peptide family.
