Kops: Chromosome segregation

Back to research groups

The Kops group studies the processes involved in chromosome segregation during cell division, with a focus on molecular mechanisms, evolution and chromosomal instability.

The main aim of our research is to understand how the cell division process gives rise to two genetically identical daughter cells. We are particularly interested in the processes that ensure correct chromosome segregation during mitosis. This is not only fascinating from a molecular perspective (how does a cell do that) and an evolutionary perspective (How has this intricate process evolved and are there meaningful differences between species?) but also has implications for health and disease. Errors in chromosome segregation are a major cause for birth defects and embryonic lethality in humans, and the most common genetic alteration in human tumors is aberrant chromosome numbers, called aneuploidy. Finally, as we and others have shown, errors in chromosome segregation during mitosis have dramatic secondary consequences on genome integrity, including translocations, deletions and chromosome shattering (chromothripsis).

Geert Kops

Geert Kops is Director of the Hubrecht Institute, and professor of Molecular Tumor Cell Biology at the University Medical Center Utrecht. His group is interested in the processes that ensure correct chromosome segregation during cell division. Errors in chromosome segregation can cause birth defects and embryonic lethality in humans and cause aneuploidy, the most common genetic alteration in tumors. The Kops group studies the signaling networks that regulate chromosome segregation, the evolution of cell division processes and the role of chromosomal instability in cancer.
