-
-
?
cohesin + H2O
?
cohesin Is cleaved with similar kinetics and timing near the centromere and telomere. Separase inhibition of PP2ACdc55 is necessary for robust cleavage of cohesin
-
-
?
cohesin + H2O
?
-
separase-mediated cleavage of cohesin at interphase is required for DNA repair. It is proposed that the securin-separase complex might aid DNA repair by removing local cohesin in interphase cells

cohesin + H2O
?
Thermochaetoides thermophila
the enzyme cleaves the kleisin subunit of cohesin and opens the cohesin ring to allow chromosome segregation

cohesin + H2O
cleaved cohesin
-
separase is required for sister chromatid separation during mitosis
-
-
?
cohesin + H2O
cleaved cohesin
-
separase, i.e. Esp1, is implicated in the removal of cohesin which links sister chromatids in the S-phase and is postulated to be a specific protease or a positive regulator of protease against cohesin
-
-
?
cohesin + H2O
cleaved cohesin
-
separase triggers anaphase by cohesin cleavage, and triggers the release and activation of the phosphatase Cdc14 independently of its protease activity
-
-
?
kendrin + H2O
?
kendrin, also named pericentrin and specifically cleaved at a consensus site (R2231), is a crucial substrate for separase at the centrosome, protecting the engaged centrioles from premature disengagement and thereby blocking reduplication until the cell passes through mitosis
-
-
?
Rec8 + H2O
?
resolution of chiasmata in oocytes requires separase-mediated proteolysis. Proteolytic cleavage by separase is essential for Rec8's removal from chromosome arms and for chiasma resolution but not for the first polar body

Drosophila sp. (in: flies)

separase is primarily required for sister chromatid separation during mitotic and meiotic division, by cleavage of a subunit of the cohesin complex. Separase is also and perhaps indirectly important for epithelial integrity

-
auto-cleavage of separase coordinates multiple aspects of the G2/M programme in human cells, thus contributing to the timing and efficiency of chromosome segregation
-
-
?
additional information
?
-
-
Hela cells lacking separase are delayed or arrested at the G2-M phase transition. Without separase, cells also have a prolonged prometaphase. Separase is required at multiple cell cycle stages including the interphase. Its role in promoting loss of sister chromatid cohesion might be important preferentially at arms but not centromers

-
-
downregulation of PP2A(Cdc55) phosphatase by separase initiates mitotic exit. At anaphase onset, PP2A(Cdc55) activity is downregulated in a separase-dependent manner, triggering a first wave of Cdk-dependent Net1 phosphorylation and Cdc14 release. Separase is the essential trigger for Cdc14 activation in anaphase
