    ..We propose that AIR-2 promotes the release of chromosome cohesion via phosphorylation of REC-8 at specific chromosomal locations and that CeGLC-7alpha/beta, directly or indirectly, antagonize AIR-2 activity. ..

    ..Condensin mediates chromosome condensation during prophase, and condensin-independent pathways contribute to chromosome condensation during metaphase. ..

    ..We propose that, in C. elegans, a LAB-1-mediated mechanism evolved to offset the challenges of providing protection against separase activity throughout a larger chromosome area. ..

    ..Thus, a pool of phosphatase activity associated with a kinetochore-localized nucleoporin contributes to two key events that occur during M-phase exit in metazoans: kinetochore disassembly and nuclear reassembly. ..

    ..Our results thus define a new pathway that limits the number of daughter centrioles produced each cycle. ..

    ..We propose that CeGLC-7 beta is involved in chromosome dynamics including histone H3 dephosphorylation. ..
