Marine Biological Laboratory, Woods Hole, Massachusetts, USA
J Cell Biol 141:703-13. 1998..We discuss the possible biological implications of the existence of two distinct anaphase A mechanisms and their differential contributions to poleward chromosome movement in different cell types...
- Tubulin and FtsZ structures: functional and therapeutic implicationsA Desai
Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA
Bioessays 20:523-7. 1998..This structural inferiority complex has finally been lifted by two recent papers describing the structures of the alpha beta tubulin dimer and FtsZ, a protein similar to tubulin that is essential for cell division in prokaryotes...
- Roles of polymerization dynamics, opposed motors, and a tensile element in governing the length of Xenopus extract meiotic spindlesT J Mitchison
Marine Biological Laboratory, Woods Hole, MA 02543, USA
Mol Biol Cell 16:3064-76. 2005..The response to microtubule destabilization suggests that an unidentified tensile element acts in parallel with these conventional factors, generating spindle shortening force...
- The spindle: a dynamic assembly of microtubules and motorsT Wittmann
Department of Cell Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, California 92037, USA
Nat Cell Biol 3:E28-34. 2001..Here we describe the structural and dynamic properties of the spindle, and introduce the current concepts regarding how a bipolar spindle is assembled and how it functions to segregate chromosomes...

Cell Division Group, Marine Biological Laboratory, Woods Hole, MA 02543, USA
Mol Biol Cell 15:5603-15. 2004..Our results highlight the importance of two processes, chromatin-initiated microtubule nucleation, and sliding forces generated between antiparallel microtubules, in self-organization of spindle bipolarity and poleward flux...
- XKCM1: a Xenopus kinesin-related protein that regulates microtubule dynamics during mitotic spindle assemblyC E Walczak
Department of Cellular and Molecular Pharmacology, University of California, San Francisco 94143 0450, USA

- Functional analysis of kinetochore assembly in Caenorhabditis elegansK Oegema
Max Planck Institute of Molecular Cell Biology and Genetics, 01307 Dresden, Germany
J Cell Biol 153:1209-26. 2001..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...

Cold Spring Harbor Laboratory, New York 11724 2220
J Biol Chem 269:12014-23. 1994..These results suggest that of the four members of the casein kinase-1 family recognized in fission yeast, one member, Cki2, may contribute to the regulation of cell morphology...
