    ..Furthermore, kinetochore assembly and the recruitment of CeINCENP to chromosomes are independent. These results suggest distinct roles for the kinetochore and the chromosomal passengers in mitotic chromosome segregation. ..

    ..We discuss the rationale for a bipartite checkpoint mechanism in which a core Mad1(MDF-1)/Mad2(MDF-2) signal generated at kinetochores is integrated with a separate cytoplasmic Mad3(SAN-1)/BUB-3-based pathway. ..

    ..We suggest that separation is controlled by a meiosis-specific chromosomal domain to coordinate cohesin removal and chromosome segregation. ..

    ..elegans bub-1 is required both maternally and zygotically. Further, our genetic analysis is consistent with that the function of bub-1 in C. elegans is likely similar to its yeast and mammalian homologs. ..

    ..Thus, the finding that PLK-1 functionally substitutes for Mps1 in checkpoint initiation in C. elegans uncovered a role for Plk1 in species that have Mps1. ..

    ..These results suggest that dynein and Lis1, albeit functioning in identical processes, are targeted partially independently of one another. ..

    ..These results delineate an interaction between BUB-1 and MAD-1 that targets MAD-1-MAD-2 complexes to kinetochores and is essential for spindle checkpoint signaling. ..
