Kinetochores are macromolecular proteinaceous assemblies that are assembled on centromeres and attach chromosomes to the spindle fibres and regulate the accurate transmission of genetic material to daughter cells. Multiple protein sub-complexes within this supramolecular assembly are hierarchically assembled and contribute to the different aspects of kinetochore function. In this work we show that one of the components of the Saccharomyces cerevisiae kinetochore, Nkp2, plays an important role in ensuring accurate segregation of chromosomes. Although this protein is not conserved in higher organisms, we show that it interacts with highly conserved components of the kinetochore genetically and regulates chromosome segregation. We show that in kinetochore mutants like ctf19 and mcm21 the protein is mislocalized. Furthermore, removal of Nkp2 in these mutants restores normal levels of segregation.
