We have cloned and characterized the Schizosaccharomyces pombe gene mog1(+), which encodes a protein with homology to the Saccharomyces cerevisiae Mog1p participating in the Ran-GTPase system. The S. pombe Mog1p is predominantly localized in the nucleus. In contrast to the S. cerevisiae MOG1 gene, the S. pombe mog1(+) gene is essential for cell viability.(More)
Shugoshin 1 (SGO1) is required for accurate chromosome segregation during mitosis and meiosis; however, its other functions, especially at interphase, are not clearly understood. Here, we found that downregulation of SGO1 caused a synergistic phenotype in cells overexpressing MYCN. Downregulation of SGO1 impaired proliferation and induced DNA damage(More)
