Single-cell phenomics in budding yeast.

abstract：:Despite the fact that the chromosomal passenger complex is well known to regulate kinetochore behavior in mitosis, no functional link has yet been established between the complex and kinetochore structure. In addition, remarkably little is known about how the complex targets to centromeres. Here, in a study of caspase...
