evidence: Iain Cheeseman investigates the role of the kinetochore , a group of proteins required for cell division and chromosome segregation .. kinetochore. kinetochore. proteins. proteins. cell division. cell division. chromosome segregation. chromosome segregation. This core network of proteins facilitates the attachment of chromosomes to microtubule polymers -- the spindle structures that attach to the ends of cells , pulling and dividing them during cell division .. proteins. proteins. cell division. cell division. chromosomes. chromosomes. microtubule. microtubule. spindle. spindle apparatus. The kinetochore is critical to ensuring duplication without loss or damage to the genetic material .. kinetochore. kinetochore. Cheeseman is also investigating the activities of the individual molecular machines that make up this structure and how these proteins are controlled and regulated .. proteins. proteins. Cheeseman is noted for discovering multiple new kinetochore proteins within yeast , the Caenorhabditis elegans worm and human cells .. kinetochore. kinetochore. proteins. proteins. yeast. yeast.

He has focused particularly on the proteins that are required to generate connections with spindle microtubules .. proteins. proteins. spindle. spindle apparatus. He recently demonstrated a critical and direct role for a protein complex called Ndc80 -LRB- coded for by the gene NDC80 -RRB- in directly associating with microtubules .. NDC80. NDC80. Because many cancers may be driven by errors in chromosome segregation , it is hoped that Cheeseman 's studies will provide payoffs in cancer research .. chromosome segregation. chromosome segregation. Certain cancer drugs target the connection between chromosomes and spindle microtubules , and some of the major proteins in the kinetochore complex have been implicated in leukemia and other diseases .. kinetochore. kinetochore. proteins. proteins. chromosomes. chromosomes. spindle. spindle apparatus. leukemia. leukemia.
