analysis of the homozygous zebrafish mutant cds (cease&desist), bearing a mutation in the separase gene, reveals high levels of polyploidy and aneuploidy, spindle defects, and a mitotic exit delay in mutant embryos. Carcinogenesis studies demonstrate that cds heterozygous adults have an eightfold increase in the percentage of fish bearing epithelial tumors |

clear evidence for a non-proteolytic function of separase is provided: by separase gene deletion in mouse oocytes it is shown that separase null-oocytes are unable to either destroy chesin along chromosome arms or segregate homologous chromosomes and these oocytes are unable to complete cell division. Microinjection of wild-type separase mRNA in separase null-oocytes restores normal homologue disjunction and polar body extrusion |

generation of human cells with one hESP allele-encoding uncleavable protein and another allele harboring a single cleavage site, the cells grow slowly owing to cell cycle delay, in particular during G2/M transition, but not when it was expected, i.e. during anaphase |
