3.4.22.49 malfunction meiotic expression of ESP RNA interference blocks the removal of cohesin during both meiosis I and II, results in alterations in nonhomologous centromere association, disrupts the radial microtubule system after telophase II, and affects the proper establishment of nuclear cytoplasmic domains, resulting in the formation of multinucleate microspores Arabidopsis thaliana
3.4.22.49 physiological function Separase is essential for sister chromatid separation during anaphase II. Separase-mediated proteolytic cleavage of the alpha-kleisin subunit of the cohesin complex at the metaphase-to-anaphase transition is essential for the proper segregation of chromosomes. Separase is also involved in mitotic and meiotic anaphase spindle assembly and elongation, interphase spindle pole body positioning, and epithelial cell reorganization Arabidopsis thaliana
