Mitotic spindle morphogenesis: Ran on the microtubule cytoskeleton and beyond.
Assembly and disassembly of the mitotic spindle are essential for both chromosome segregation and cell division. The small G-protein Ran has emerged as an important regulator of spindle assembly. In this review, we look at the role of Ran in different aspects of spindle assembly, including its effects on microtubule assembly dynamics and microtubule organization. In addition, we examine the pos...
متن کاملA mitotic role for Mad1 beyond the spindle checkpoint.
Unattached kinetochores generate an anaphase inhibitor, through the spindle assembly checkpoint (SAC), that allows cells more time to establish proper kinetochore-microtubule (K-MT) linkages and thus avoid aneuploidy. Mad1 is the receptor for Mad2 at kinetochores, where it catalyzes the formation of Mad2-Cdc20 complexes, an essential part of the anaphase inhibitor, but whether it has any other ...
متن کاملMitotic cell death induction by targeting the mitotic spindle with tubulin-inhibitory indole derivative molecules
Tubulin-targeting molecules are widely used cancer therapeutic agents. They inhibit microtubule-based structures, including the mitotic spindle, ultimately preventing cell division. The final fates of microtubule-inhibited cells are however often heterogeneous and difficult to predict. While recent work has provided insight into the cell response to inhibitors of microtubule dynamics (taxanes),...
متن کاملThe mitotic spindle checkpoint
One of the most awe-inspiring demonstrations in biology is a timelapse video of mitosis viewed with high magnification phase contrast or Nomarski DIC microscopy. From initial chaotic movement comes the orderly alignment of chromosomes at the metaphase plate followed by a flawlessly synchronous splitting of the chromosomes and their gliding separation to the two mitotic poles. Enforcing the timi...
متن کاملGSK3 Regulates Mitotic Chromosomal Alignment through CRMP4
BACKGROUND Glycogen Synthase Kinase 3 (GSK3) has been implicated in regulating chromosomal alignment and mitotic progression but the physiological substrates mediating these GSK3-dependent effects have not been identified. Collapsin Response Mediator Protein 4 (CRMP4) is a cytosolic phosphoprotein known to regulate cytoskeletal dynamics and is a known physiological substrate of GSK3. In this st...
