Structure, Function & Regulation of Centromeres and Kinetochores

Proper attachment and segregation of chromosomes are of key importance for ensuring genome stability, and are essential for cell and organismal viability and avoidance of human diseases such as cancer. In eukaryotes, this is achieved by the assembly of the kinetochore complex at a single site on each chromosome, the centromere.

Surprisingly, centromere identity and propagation are epigenetically regulated in most eukaryotes. Active centromeres contain a centromere-specific histone H3-variant (CENP-A), which is required for kinetochore assembly. Kinetochores are intricate reactive machines responsible for chromosome movement during mitosis, and for monitoring the fidelity of microtubule attachments prior to anaphase segregation (the spindle assembly checkpoint).

The last four years has seen an explosion of information concerning our understanding of the regulatory mechanisms responsible for centromere and kinetochore assembly and function. Detailed insights are being provided by intricate structural and functional analyses of components and complexes. The development of in vitro and in vivo reconstitution systems has revealed how different components are regulated. This, coupled with novel live cell imaging and super-resolution microscopy, has demonstrated the dynamics of components, and how centromere and kinetochore assembly are regulated within the cell cycle. However, proteomic approaches have identified approximately 200 centromere-associated proteins in vertebrates, highlighting the need for more comprehensive structural and functional analyses.

At this critical moment, it is essential to create an opportunity for integration of information from diverse approaches and systems. Our principal aim is to bring together molecular geneticists, cell biologists, biochemists and structural biologists to discuss their latest findings, define the current challenges in the field, and stimulate junior and senior scientists to address the key questions. This will be a landmark meeting and will have great impact on progress in the field.
