| abstractText | Centromere protein C (CENPC) is a key protein that has been localized to the inner kinetochore plate of active mammalian centromeres, Using gene targeting techniques, we have disrupted the mouse Cenpc gene and shown that the gene is essential for normal mouse embryonic development, Heterozygous mice carrying one functional copy of the gene are healthy and fertile, whereas homozygous embryos fail to thrive, In these embryos, mitotic arrest and gross morphological degeneration become apparent as early as the morula stage of development, The degenerating embryos demonstrate highly irregular cell and nuclear morphologies, including the presence of a large number of micronuclei, Mitotic chromosomes of these embryos display a scattered and often highly condensed configuration and do not segregate in an ordered fashion, These results describing the phenotype of the mutant mouse embryos indicate that CENPC has a direct role in the mitotic progression from metaphase to anaphase. |
