... the cortical granules for their timely exocytosis is largely unknown. In Caenorhabditis elegans , the recruitment of separase, a downstream effector of the fertilization signal, to the cortical granules is essential for exocytosis because separase is required for membrane fusion. However, the molecule...

... that premature disengagement results from untimely activation of the anaphase-promoting complex (APC/C), leading to securin degradation and release of active separase. Although APC/C activation during G2 arrest is dependent on polo-like kinase 1 (Plk1)-mediated degradation of the APC/C inhibitor, early mitotic...

Schumacher; Matthew Wallenfang; Andy Golden Mutations in the Caenorhabditis elegans separase gene, sep-1 , are embryonic lethal. Newly fertilized mutant embryos have defects in polar body extrusion, fail to undergo...

...Rahul Pandey; Stefan Heidmann; Christian F. Lehner Separase cleaves a subunit of the cohesin complex and thereby promotes sister chromatid separation during mitotic and meiotic divisions. Drosophila separase associates with regulatory subunits encoded by the pimples and three rows genes. Three rows...

...Oliver Leismann; Christian F. Lehner Sister chromatid separation during exit from mitosis requires separase. Securin inhibits separase during the cell cycle until metaphase when it is degraded by the anaphase-promoting complex/cyclosome (APC/C). In Drosophila , sister chromatid separation proceeds...
