Department of Cellular and Molecular Medicine, Ludwig Institute for Cancer Research, University of California, San Diego School of Medicine, La Jolla, 92093, USA
Curr Biol 15:771-7. 2005..Our results establish that the key role of HCP-1/2 is to target CLASP(CLS-2) to kinetochores, and they support the recently proposed model that CLASP functions to promote the polymerization of kinetochore bound microtubules ...

Department of Molecular and Cell Biology, Barker Hall, University of California, Berkeley, Berkeley, CA 94720, USA
J Cell Biol 163:215-22. 2003..We propose that a molecular core consisting of CENP-A, -C, -H, and Ndc80/HEC has been conserved from yeast to humans to link centromeres to spindle microtubules...
- Phospho-regulation of kinetochore-microtubule attachments by the Aurora kinase Ipl1pIain M Cheeseman
Department of Molecular and Cell Biology, University of California, Berkeley, Berkeley, CA 94720, USA
Cell 111:163-72. 2002..Our systematic mutational analysis of the Ipl1p phosphorylation sites demonstrated that the essential microtubule binding protein Dam1p is a key Ipl1p target for regulating kinetochore-microtubule attachments in vivo...

Mol Biol Cell 19:587-94. 2008..These findings explain discrepancies in kinetochore assembly pathways between different organisms and reveal a surprising plasticity in the assembly mechanism of an essential cell division organelle...
- Kinetochore protein interactions and their regulation by the Aurora kinase Ipl1pChing Shang
Department of Molecular and Cell Biology, University of California, Berkeley, California 94720 3202, USA
Mol Biol Cell 14:3342-55. 2003..Strikingly, we found that the Dam1p-Ndc80p and Dam1p-Spc34p interactions were weakened by mutations mimicking phosphorylation at Ipl1p sites, allowing us to formulate a model for the effects of phosphoregulation on kinetochore function...
