    Mol Biol Cell 11:1305-13. 2000
    ..Overexpression of SMC2, a gene necessary for chromosome condensation, and a homologue of the XCAP-E condensin, does not suppress brn1, pointing to functional specialization of components of the condensin complex...

    I I Ouspenski
    Department of Cell Biology, Baylor College of Medicine, Houston, Texas, 77030, USA
    Exp Cell Res 244:171-83. 1998
    ..These features are shared, in part, by a mutation in RanGEF1, but not in RanGAP1. The yrb1-21 allele suppresses a RanGEF1 mutation, indicating that RanGEF1 and RanBP1 may be involved in the same essential function...

    I I Ouspenski
    Department of Cell Biology, Howard Hughes Medical Institute, Baylor College of Medicine, Houston, TX 77030, USA
    Nucleic Acids Res 27:3001-8. 1999
    ..This work shows that analysis of dosage effects is complementary to mutational analysis of chromosome transmission fidelity, as it allows the identification of chromosome stability genes that have not been detected in mutational screens...

    I I Ouspenski
    Department of Cell Biology, Baylor College of Medicine, Houston, Texas 77030
    J Biol Chem 270:1975-8. 1995
    ..Thus RanBP1 is a functional component of a highly conserved molecular system that affects diverse cellular processes. The availability of this gene in S. cerevisiae provides a genetic system for the analysis of RanBP1 function in vivo...
